It's almost as good as the quick-lube "Here is your air filter, notice it has dirt on it (even though it's a month old) - we should replace it for $80".

"But isn't the purpose of the filter to collect dirt?"

"Duh ok we'll put it back"

Didnt happen to me.

Nitrogen is a huge sham/waste of $.

That is silly. If one goes bananas is means they did not install it properly. Had this happen to me when I replaced my last tire. Took it back to them and they just replaced the whole sensor. They apologized for me having to come back and admitted they had screwed up and just replaced it. No problems since.

There's Nitrogen in Oxygen.....The worst "lets see how many suckers we can make money off of" scheme to date for cars. Air is free. Why would you want to pay money for only part of it. People are dumb. OP I hope you got the answers you needed before this thread goes feet up.

There's nitrogen in the air. And Oxygen in the air. But when you put Nitrogen with your Oxygen then you get Nitrous Oxide which I would not recommend putting in your tires. Unless you want more horsepower - fast and furious style.

Wow! The BS from the dealers is amazing. My BMW dealer refused to repair a nail in a run flat and said they could not be repaired just from a phone call to them. Then they told me to drive it with a flat to them so they could replace the tire. I took it to a tire shop and they fixed it. They said if the inside sidewall is broken down (it was driven on flat) it could not be repaired but not my case and true, I found it flat in my garage and did not drive the car. Also the last two BMW’s I owned had run flats that I got rid of soon after I got the car. I bought wheels and tires from Tire Rack. If you ae looking for inexpensive tires that meet the cars ratings the Hancook Vetus V12 are a really good choice. I had them on my 135i and the rear tires were about $160 each. I then bought a used BMW Mobility kit off e-bay. I also bought a tire plug kit just in case.

Great post. i hope EVERYONE reads it. So much bad info about repairing RFT.

[Cyberdemon]

Regarding repairing RFTs - generally if the car sits on the sidewall, it will cause damage to the bead. It may be repairable but is not advised.

If you get a slow puncture and get it patched right away, you may be OK.

I had a puncture in my RFT which they repaired twice, but wouldn't hold because it was so close to the edge of the tire they had to try to patch it on the curve inside the tire and it would not hold for more than a few days.

Some shops will also fail to repair high performance run flats or any high performance tire simply for liability reasons. They don't want you to have a blowout at high speeds and potentially sue them, it isn't worth the $15 they make off repairing the puncture.

Most tire shops will not try to repair a run flat unless the manufacturer recommends repairing them. Most manfactuers do recommend repairing them. Some do not. Perelli is one of the ones that does not. Liabilty issues.

Did you mean damage to sidewall? I've never met anyone that would attempt a repair on any tire that was anywhere but in the tread.

I mean if you get a puncture and the tire sits on the sidewall flat for an extended period of time, it is recommended to NOT repair it. There is a chance that having all of the weight on the sidewall has compromised it's integrity.

IE if you come out to a car that's sitting flat, it's not advised to repair it.

If you can get the tire repaired while it still has air in it (and keep it inflated IE a slow leak) then repairing it should not be an issue.

I don't have a M235 but I do have an 06 330i that originally came with runlets, I hate them with a passion, they don't do anything well. I switched at 50,000 miles to regular tires, joined AAA so I could get a tow if I had a flat and I am now over 204,000 miles so 154,000 miles on conventional tires. You could not pay me to go back to run flats. BTW I have used AAA twice, not because of a road failure but because I wasn't paying close enough attention to the wear on the inside rear tires and wore through because of the camber. I felt stupid the first time I neglected to pay attention and then turned around and did it again about a year later. I drive 30,000 miles a year so I go through a lot of tires anyway.

You got to love the scare tack ticks some people use to try to keep you on run flats.

Getting back to this topic.....
Any of you guys think there is a REAL safety improvement running runflats??? for example..... running over a significant size Stone/Pothole at 100m/h... regular tires might desintegrate while the runflats won´t???
Last afternoon I managed to avoid 3 potholes, but not the fourth so my tire is gone... threads are out, it didn´t loose any pressure, tough (safety plus).
RF are about $100 over regular tires here.

The problem with runflat tires is their lack of repairability. Some places will not try to repair runflat tires due to design and safety reasons, some will. Discount Tire will repair any regular tire for free, however, depending on the damage.

RFT have the advantage with pothole survivability with the thicker sidewalls, but ride/comfort suffer and so does the wallet. I personally prefer regular tires as the sidewalls communicate more to the driver than RFT. RFT provide false confidence with high turn-in speed but when they roll i find it unnerving how the tires react.

I had the RFTs on my 135i for about 3-4 months before I made it my mission to bald them out and replace them. It was like a brand new car with non-RFT tires!

[OpenAir]

Is it me or do RFT's also make the care "bounce", for lack of a better word. These are my first RFT's and they seem to rebound, bounce, something...it's getting old. Was also thinking about some 17's with AS3's

Just made the switch from run-flats to Michelin Pilot Sport A/W3's. Yes... it changed the handling. Made it better in driving dynamics AND improved the road noise and ride.
Waiting for the temporary spare to arrive to place in the trunk. Can of fixit flat for the time being...just in case.

THANKS to all in the forum for your advice.

Where did you get a spare?

Where did you put it? I mean - where does it fit?

[tencazzo]

Guys, I want to get rid of Potenza RFT so what do you about used (4000km) Michelin Piot Super Sport VS new Hankook VENTUS S1 EVO2? Are PSS so much better over Hankook even if they are used?
