Run Flat Tires Wear Quicker, Cost More Than Regular Tires

A popular new tire that is becoming standard on a growing number of cars is generating hundreds of complaints.

Many drivers say it has a flaw, and when they try to replace it they run into another problem, reported 5 On Your Side's John Matarese.

The new type of tire is supposed to never go flat. If you run over a nail, you can drive all the way home.

However, many owners of these tires are unhappy.

Tom Lehn says the tires are the worst feature on his new Toyota Sienna minivan.

"You can see it's worn all over, but especially at the edges. It's wearing faster than expected," said Lehn.

Lehn bought the run flat tires to keep his wife and kids safe, so they wouldn't be stranded by a flat.

Then he learned that the tires can cost twice as much as a regular tire.

"It was $275 for one tire," said Lehn.

Tire shop owner Dan Brogan is not surprised by the high cost.

He said run flats are costly to produce because of the special hardened rubber sidewalls they require, which allow them to keep going with no air.

And that tougher rubber won't last as long.

"You can't have everything. A tire that runs flat and lot of mileage out of it, you can't have both," said Brogan.

But some car owners don't buy it, and have filed a class action lawsuit against Toyota and Dunlop tires.

The suit claims Sienna minivan tires last only 10,000 to 20,000 miles, and have to be replaced annually at cost of $1,300 or more.

Toyota and Dunlop won't comment on pending litigation, but Toyota dealers say the tires should last 30,000 miles in normal use.

Despite their price, run flats can still be a good feature if you do a lot of interstate driving or commute through a rough part of town.

That peace of mind might be worth $250.

i personally dont like them either, but what do you do if your car doesn't come with a spare tire.... 6 series and such....

They are never avvailable, special order, and most palces are sold out.... my firend payed $400 per tire for his six series. had no choice.
 
Well I think run flats are a good thing, the problems with ride quality seems to have disappeared with the new 3er! They also mean the car has more room and stop you getting stranded somewhere! Also, when all car companies use them (I think they will) the cost will come down! It's only because it's something new that it's expensive!

It isnt new, and all companies are going to use them...
 
I bet that by replacing the RF tires with normal ones the ride quality will increase significantly no matter what car we are talking about.
 
I hate them. You have all mentioned some reasons, and they are crap performance tires!
 
I know many BMW onwers that changed their run-flats to proper tires.
M5 dont use flat-tires at all, guess why...

That's why the 3er's suspension was designed to run on RFTs... it hasn't received the complaints the 5er has.

Personally until the technology is ready, I'd get normal tires and have a can of mousse in the trunk. that should solve the problem for now. Eventually the cost and availbility will be better.

how will the can of mousse solve the problem? that is for after the puncture.....if you are going along a motorway at 100mph and your tyre blows out what do you do....think oh ill get the mousse out and repair it (when you have recovered from the accident of course or if you dont get injured get killed while repairing the tyre next to the motorway...) or you just spend that little extra bit of money for tyres which mean you dont lose control of your car ay 100mph with a blow out....and can continue going for a few hundred more miles until you get home then change it? i know which one i would rather have.....
 
Doesnt matter if you drive Run-flats or no run-flats, you can get a puncture with all kind of cars.
I was once driving an old Golf on the freeway, driving 120km/h and got a puncture on one of my tires. But it was no drama at all, maybe I was lucky but nothing happen, I just parked the car and fixed the puncture while big trucks was passing me and that was the only drama for me that day.
 
Predominantly BMWs I think, 1er, 3er, Z4, 5er, 6er and so on.

I personally am dead against run-flats (the chances of a puncture are far, far higher than an outright blowout) and modern electronic systems are well up to the task of keeping a car stable in the event of an occurence of the latter.

The problem comes in on distance driving: run-flats can only travel 80 km at 80 km/h and in South Africa or Australia thats just not far enough because the distances between small towns can be far greater than that. So after 80 clicks of driving and your run-flats are shot, then what? You're stuck, that's what. Run-flats just don't cut it in Africa or other wide-open spaces.

Give me the additional get-you-there security of a pukka spare wheel anyday.
 
well it depends on the manufacturer of the run flats......this is just one manufactuer who is being complained about...i have seen other run flats on some site which are capable of running flat for far longer than 80km....
like just me said he was passed by lots of lorries on the motorway.....the amount of people that get killed on the hard shoulder of the road....

Well if you get a blow out, you are screwed. I'm not saying it won't happen, but when was the last time you got a blow out. I was talking about a puncture (nails and screws) which slowly decreases the air pressure.
Even if you have tires that can run further than 80km, it still doesn't solve the problem. So let's say a tire can run 200km, then what? In a country like SA when you go cross country, the distance can be much greater than that. PLUS these tires aren't readily available at Joe's tire shop. Sometimes it takes days to order them, and this is the States. Safest solution is to have a spare in the boot and sacrifice trunk space...
 
Im not sure if the benefits of these tires outweigh the drawbacks. But here in OZ BMW uses this as quite a significant feature when marketing the cars. Every salesperson we spoke to explicitly mentioned these tires as a feature of the cars on more than one occaision.

They do everywhere... it is a good technology but the problem is that people aren't ready for it. Until these tires become readily available (which i'm sure a lot of BMW salesman don't mention), this technology is just not good...yet.
 
I guess you have to start somwhere though, and Kudos to BMW for leading the way. :usa7uh:

These will be standard fit on 100's of models in just a few years.
 
There is a reason BMW is one of the first to start the run flat trend. BMW's had been critisized in the past for having less space in the rear seat and in the trunk than Mercedes and Audi. Without a spare tire they could increase the space at least with 40-50 lt more.

True... but the whole run flat techonology did not start with the E90 though. I think it might have started with the 7er, if not then the 5er. And those were options that the owner could choose. Therefore, I'm not even sure if that was the reason why BMW went with it. It could very well be possible that the tire manufacturers had something to do with it and that BMW wanted to be the first ones that start using it commonly.
 
I was thinking of putting RF tires on my car! I have 16' rims. So you guys say no to me, right?
