Anyone use Run flat tires?

BATMANs · 28 July 2008

Just got a set installed and sure enough, I had a nail puncture over the weekend.

Tires looked and felt like it was underinflated, but i was able to drive it home.

I was wondering it these tires and be repaired or are they toss aways once you have damage?

I hear conflicting stories on this matter....

WTF? run flats on NSX?:tongue:

RPM217 · 28 July 2008

No repairs would ever be done by a legitimate tire shop. Once the run flat feature is utilized, it's the trash heap. They ride harder, louder and don't handle as well, but if you need the trunk space, or don't carry a spare, they'll allow you to drive home safely. I know many people who switch from run flats to regular tires, but not many who do it the other way around.

Apparently depends on manufacturer. Some tires will say so right on the sidewall to replace and not repair.

I heard that the tire can be repaired, but the speed rating is no longer guaranteed......as if.....

I would say that statement applies to standard tire depending on where the puncture is located. But I'm not sure if that would apply to a runflat.

all tires with punctures at or near the sidwall should be recycled....

I believe the issue about replacement is due to the nature that the flat tire will be driven on for 50 to 100 miles. The duration they say it'll help get the driver to safety. In that amount of time and mileage, the heat and wear is what I'm sure the manufacturer is worried about and want the tire to be replaced.

My take is:

So regular tire, you get a flat and know about it fairly quickly. Pull over before any damage is done and generally HAVE to put on the spare or call for help since it's not safely drivable, rendering the wheel useless as flat but useful for repair.

Run flat, you get a flat and I'm guessing won't really notice about it for a long time or you drive it to the nearest safe location or tire shop which could be far away potentially. By that time, the wear and tear has "destroyed" the tire.

Doesn't it say so on the sidewall of the tire or in the documentation? Manufacturer's website?

My understanding is that most run flats are intended to be used with a tire pressure monitoring system, so that you DO notice it right away... no?

Also keep in mind that one of the most common tire problems is a slow leak caused by a puncture on the tread (not in or near the sidewall). I don't know whether this is considered repairable or not; the NSX owners manual cautions against using any repaired tire, but I've known people who have done so (and the standard caution noted above applies, regarding speed ratings).

I have an m6 and 645---Both have run flats. Both Have a system that monitors the pressure. BMW and most places wont repair, patch or plug RUN FLATS....The Integrity is lessened after a flat...I was blowed 450.00 tire with 98 percent thread...TRASH. I found someone to repair both (25.00). However, I only drive for 2 - 6 miles before it was changed. The more you drive the more the integrity is effected. 2 years later both are fine. Their is more road nose----just a lil and if I was to take a curve at 90 mph plus, it sways a lil more then normal but not noticeable to someone who never drove the car before. If I was in Germany---I would change it for I am sure I would run the car up to the 155 gov speed (US) . If you drive your car 1000 miles a year---Save your money...
Also you can go to Pep Boys, AutoZone, Etc....and put on the tire pressue caps that change colors if you running low....10.00 a set....

I run them on all my other non RUN FLAT cars.....

Cheap But Works

I just use regular tires and keep an pair of inflator cans in the trunk to help me limp to the nearest service center. My car is modified to the point where the oem spare in pretty useless.

Yeah, when they're oem tires from the factory. lots new cars with or without runflats now come with a dash tire pressure warning system anyhow. But there are times, like Batman here, who run the runflat for the sake of having a runflat.

I should mention that the RFT are on the GTO, not the NSX.

GTO doesn't have a spare wheel.

So there is a possibility that if I repair it and drive across to LA from SF that this may be the last time ya'll hear from me.

Wonderful!

I ran into this same problem recently while shopping for an Odyssey van.
All Touring models up to MY08 came with run flats and I've read horror stories about them and how people would take them off.
I chose to get an EX-L model so I wouldn't have to be concerned with them.

BATMANs · 30 July 2008

Will this work in case I get a flat with the RFT?

KooLaid · 30 July 2008

That stuff is nasty. It's liquid glue in a can. Gross stuff to clean off when they need to change your tire later on.

I've used slime TUBELESS in my sportbike tire and it worked for the entire 8000 miles till I wore it out. That's what I keep in my nsx now but it requires an air pump and possibly a few attempts at airing it up to make it seal. But it works and works great.

That fix a flat stuff seemed to melt rubber when I put it into my bicycle when I was little.

All i have is an inflater, no spare, no jack, nothing. I ran over a sheet rock screw and luckily it went flat in the garage. The MFR did not recommend run flat tires, just the Pzero Corsa's or Rossa's...

So a tire plug kit and a portable pump is suffice for the long trip?

only good enough to get you to a tire shop that can supply another tire. I would travel a long distance like that though.
That is when you run into the problem of not many places carrying those kinds of tires and even tougher in the right size.

Anyone use Run flat tires?
