Look at that nice, fresh tread: Feeling much safer with new Continental Tires on my car
I may have mentioned once–or a least a hundred times–how much I love run flat tires.
That’s because winter is a tire killer. This winter left our roads filled with potholes, patches and cracks; add to that years of neglect, and they’re a mess.
And it is precisely because of these roads that run flat tires are so great: Even with a full blown hole in your tire, you can drive 100 miles on a run flat (that happened to me; keep reading).
THE QUICK READ: Run flat tires have evolved to be less expensive, more comfortable on the road and to fit all cars. They are safer than regular tires because they can drive up to 100 miles on a flat. The Continental Tires tested here are no exception: The ride was comfortable, pricing is better and the safety factor can’t be beaten.
But potholed roads are also why run flats get a bad rap: they are known for a rough ride, especially over potholes. While SUVs or sedans with regular air-dependent tires can glide across small potholes easily and bigger craters are simply a fun ride, run flat tires hit every pothole as if you’ve hit a huge metal object, jarring the car making you think you damaged the car even if you didn’t. So when I needed new tires, it was a hard choice: Run flats, or regular tires? Luckily, vast improvements in run flat tire technology made the decision and easy one.
The Pothole That Ate My Front Tire
Reason #1 to love run flat tires: A blow out is no big thing
Last fall, I had a tire blowout while driving 70MPH on a local freeway. I hit a pothole, and the tire pressure monitor light came on, so I knew something was wrong. When I got home I saw this: A huge hole in the side of my tire.
This is my actual tire after hitting a pothole on the highway. I still replaced it with run flat tires, but this time Continentals, which have a smoother, more comfortable ride
A blown tire is a big deal: the driver may lose control of the car, the car becomes extremely difficult to control, and driving on it can ruin the wheel rim. Very often, a blown tire leads to a traffic accident because the driver loses control. I didn’t experience any of those things. Just a light on the dashboard.
Confessions of a Cheapskate: Learning Why Tire Tread Matters
Safety at a price? Why run flat tires (used to be) known for a rough ride
Run flats have a reputation for giving a rough ride. They are typically installed on performance cars—cars with a sport suspension designed to be very responsive to the driver and the road. Also, run flats are made from more rubber, less air (they do require air, but much less than typical tires). Think of them like this: run flats are like leather-soled shoes, while regular tires are like rubber-soled sneakers: One is hard on your feet and the other is easy.
Like a good pair of leather shoes, run flat tires can be pricey. The Continental Tires I tested out are priced at about $250 each installed–at least that’s what I paid when I had to buy one last year, but I thought that was a bargain because I paid $400 for a tire at the BMW dealer two years before. But I may have overpaid twice; Tire Rack has the same tire for about $220 each.
Tire blowout = new tires. Choosing run flats and hoping it’s the right choice
But of course, I needed a new tire. I needed four new tires really; it was time. I’d had a conversation with Continental Tire not long before I was offered a set of tires to review. To me, reviewing tires might be like reviewing oil or spark plugs: would I be able to tell the difference between old and new?
But I’d recently been schooled on some of the important aspects of tire performance and safety, so decided to give it a try. Continental sent me a set of tires.
I took the tires to my local Mavis Tire Discount center where I had them installed and balanced. Note: they installed them for about $100, but if I’d bought the tires there, the installation would have been included in the purchase price. I’m pretty sure I’m in the minority of customers who actually bring their tires in to be installed, but if I’d ordered them online, this would have been my installation option since I can’t do it myself.
I don’t change tires and you shouldn’t either
Reason #2: Conquering a snowy road
Despite being all weather tires, these Continental run flat tires managed to get me out of the driveway, something my old tires coudln’t do
It was time to test drive these new tires. But… it snowed. A lot. A whole lot. For months. And months. Test drives would have to wait a while because my rear-wheel drive car is impossible to drive in the snow.
Or is it? Maybe it was the tires on my car that made my car so hard to drive in the snow? So, I gave it a try. And, voila. Here is a photo of my car at the top of my driveway; you can see the tracks of the car on the driveway. My old tires were NEVER able to make it up the drive in the snow, even when they were new. So, chalk up another win for Continental, and also, a feeling of freedom in knowing that tires DO make a difference: with the right tires you’re not captive to a snowfall.
New tires and snow are a good mix: I got more traction on the road (and little snow stuck to my tires!) with a new set of Continental Run Flat tires
But still, my car isn’t great in the snow; it’s that rear wheel drive thing, which means you have very little control of the front end of the car and the rear wheels can spin and spin. Also, these tires are all weather tires, not winter tires, and what that means is I shouldn’t really drive in the snow with these tires if possible, so the car stayed parked in the garage most of the winter.
Reason #3: Spring’s bumper crop of potholes bring more bounce than ouch
But then, spring sprang! Or rather, pothole season sprang.
And here is where the test drive gets really good: a good, rough road test. If you’re behind me on the road you’ll know it because I’m the one zig-zagging around potholes and slowing to a crawl over them, except when I don’t see them and it’s too late.
And…. for the most part, driving on pothole-filled roads was fine. [Scratches head, puzzled. What?!?]
Yes. Even when I hit a pothole (or a few), the car bounced slightly, if at all. The Continental tires gave a much smoother, softer ride than my old tires, even a bit bouncy. And still, like run flat tires should, they grab the pavement around corners, at stop signs, in traffic and when driving serpentine around all those potholes, giving my car the ‘sporty’ drive feel it should have.
What to look for in a new set of tires
If you’re thinking of buying new tires, what would you like most from new tires? A softer ride? More control at the wheel? Shorter stopping distance? New tires can help with all of these. A good set of tires should provide (as these Continental tires do):
- Reasonable stopping distance: even if you slam the brakes you should be able to stop without hitting anything and without losing control of the car.
- Comfortable ride: a rough, jarring ride, the feeling that every bump or pebble might unhinge the car from its joints, and loud road noise can ruin the experience of a nice car or improve the ride of an older car.
- Safety, even with a blown tire: And to me, this is most important, even if I have to replace the tire. Because the safety of my family and the person behind the wheel matters more than anything else.
- Consider purchasing insurance. Yes, you can get tire insurance on some brands (Continental included), and it might be a good idea if you seem to have tire damage every year. If a tire is damaged, a road hazard warranty program will cover the repair of the tire or a credit toward a new tire (which all depends on the circumstances and the amount of wear on the tire). The coverage is inexpensive–$10-$20 per tire, but usually limited to a year of coverage.
OK—when I said before I thought it would be hard to review tires, I was wrong; it was pretty easy. The key is to know the car well and to be able to tell the difference between how the car drives with the new tires versus how it drove with the old ones. And when you have a really good set of tires, you’ll be really, really glad.
Disclosure: Continental provided a set of run flat tires for my review; I was not compensated for this review and all opinions expressed here are my own.
Clarification: An earlier version of this story used the term ‘inner tube’ to describe a type of tire that holds air. While inner tube technology is still used in many types of tires, more commonly car tires use pneumatic inflation systems that trap air between the tire and the wheel rim. Run flats use this technology too, but require a lot less air, thus allowing tires to function safely when completely deflated.

My friend Craig Fitzgerald pointed out that the softer ride of these new tires may also be due to the increased thickness of these tires versus my old ones, and that’s a good point. Still, the new tires are pretty thin and even on my own car, I didn’t notice the difference until I looked at the photos side by side.
While runflats are good, they’re not really suitable for larger, heavier vehicles, and with so many people buying crossovers these days, it’s going to be a while before we see runflats for things like the Nissan Armada or the Toyota Sequoia.
But I agree, being able to keep driving (on smaller cars) is fantastic, and they literally could be a lifesaver.
Thanks for the input Karl! The technology is changing, though. BMW and Infiniti are stipulating run-flat tires as standard equipment on all their cars and trucks. This allows for greater passenger safety and eliminates the weight and cost of spare tires. We expect to see more of this in the future, and also, improvements in run flat technology!
I cannot disagree more with Author. Run flat allow you drive for 50 miles but tire is unrepairable. I have to change 3 tires in span of 2 years for my MB GLC300. Gave up on these and replaced with regular tires.
Here is the scam. Auto manufacturers do not include a spare or tools forcing you to replace them for every flat 😕
I have had 3 flats in last two years. We have driven about 10 miles each time except this last time. Drove home, about 5 miles…no problem. Parked in driveway for two days, and it was completely flat!
Went to drive and started to go wop, woo, woo. Ended having it towed not wanting to break anything else.
Could I have still driven it another 5 miles to mechanic to get fixed. Would like to know for next time.
How do Pirella runflats compare to continental
I have owned 4 BMW during my life. A 3 series, a 550i, a 750li, and just purchased a 650i GC. The run flat tires are the absolute worst tires I have ever own. They don’t last long and you are lucky to get 15,000 miles out of them. They are very expensive costing about $500 each. The ride is extremely rough and you are never comfortable driving the car because you are constantly looking out for potholes.
If you do hit a pothole it feels as though your entire front end was snapped in two. The first time that happen I was so afraid that the pothole caused major damage. I no longer hesitate to change my tires to run flats. The ride is much more enjoyable and I don’t have to drive so defensively looking for potholes.
Check out the BMW forums, the far majority, 85%, hate run flat tires.
Yes, BMW loves to put low profile run flats on their cars; that’s what I had on mine. My new tires are thicker and have more cushion with a much improved ride experience. Also, I bought tires at a discount retailer for less than half the price of the dealership, about $200 per wheel installed and balanced. It pays to shop around!
Most of the problems (and added performance) being described here are the result of low profile tires – not run flat tires. Low profile tires have very short sidewalls. So they provide little cushion when driving over rough roads or hitting potholes. A low profile tire is far more prone to being cut by a pothole than a normal aspect ratio tire which have enough sidewall to cushion the blow.
But taller sidewalls flex more laterally when cornering giving the car a squishy feeling on turn-in. That leads to understeer through the turn.
Run flat tires have something like a donut around the inside of the rim. If the tire looses air the car’s weight flattens the tire until the tire’s carcass rides on the donut. The donut takes up a considerable amount of space in the tire which is why they use less air. But there really is no benefit in that alone.
My wife’s C300 doesn’t even have a place for a spare tire. She just hit a pothole at highway speeds and popped one tire and nicked the sidewall of another. Replacements were $180 each (just the tire). We got two tires (Michelins) for well less than $500 out the door. I kept the one serviceable tire. I’ll get a rim at a junk yard and have the tire mounted as a spare.
I didn’t buy tire insurance though. These tires are warranted for only 30k miles. The insurance is only 12 months. If she gets a nail I’ll mount the spare and plug the tire myself. I’ve been doing that for decades. If the tire is too damaged to plug she’ll just drive it home flat. It’s trashed anyway.
Run flats are more expensive but they do offer a worthy peace of mind, especially for young and female drivers (not that all women are incapable). I like the idea that if my wife gets a flat in a bad or desolate area or late at night or in bad weather, she isn’t forced to stop wherever she is. She can drive almost normally and get herself to someplace safe.
Plus an instant flat at highway speeds is something most inexperienced drivers just don’t handle well. The dramatic pull to one side followed by the strange handling characteristics almost always results in a spin or even flipping the car on its side. A flat in a run flat tire is practically a non-event. My wife didn’t even know until the warning light came on. She’d have surely known with a conventional tire. But then she probably wouldn’t have even got a flat with a conventional tire. Six of one, half dozen of another.
I’ve been doing tires for 10 years run flats with crake ur rims everyone
Run flats are like the convenience store of tires, you pay alot for what little convenience they provide. It’s like doing your weekly grocery shopping at 7/11. Except it’s far worse than that, please see Steve’s description above as he has described the run flat experience perfectly. Based upon her last comment, the author may have increased the aspect ratio of her new tires over the old ones. If that is the case,she did not do a fair comparison.
Run flats are horrible tires. They do blowout and leave you stranded until the tow truck comes and tows you to the dealer or a repair shop. Plus they bubble. We’ve replaced 3 tires in two years.
Most everyone one want the freedom of there own spare.
Ever automobile should have a space that fits a full size spare tire.
If you have to pay extra so be it.

I have a BMW X3 M series, 19″ tires and wheels. (40K miles on it so it’s not struts). Second set of tires now. The run flats are GoodYear that are about $400/tire, give or take. Absolutely the worst riding tires I have ever had, with one exception which I’ll go into going forward. Every little pothole, expansion joint rattles the entire car. I’m embarrassed to have people ride in my car as it jars their teeth loose at every little to big pot hole or whatever. I’m switching to regular tires with a pump and sealant.
My last car was a year old Lexus GS350. I bought from an out of town dealer because it had everything I wanted, but was a 200 mile drive from home to pickup & trade. I drove that new purchase home and changed the run flats when I got home. The WORST riding/handling tires I had experienced. New non run flats made the car a dream to drive and handle, and I lived in an area that encountered a fair amount of snow each year. I had AWD.
Lastly, in the last 30 years I haven’t had a flat or a blow out on any car I’ve had and I change cars every 2-3 years, and drive typically 15-20,000/year. Up until the Lexus and then the X3 I always ran standard quality tires-no run flats. Bridgestone, Michelin, continental and Pirelli. The whole run flat concept IMO is another opportunity to save the manufacturer money, and who pays as always for hat shortcoming? Of course, the consumer.
