Run-Flat Tires vs Non Run-Flat Tires
I have the OEM bridgestone Potenza re050a tires (rft), but I want to buy a new set of tires to install in the future.. The OEM tires have about <10k miles left on them, so I would like to plan for the future maybe even some BBS rims to match.
Did some research, and mostly people would agree that regular tires will out-perform rft? Is this true? How come? To clarify "out-perform", i mean, wet/dry traction, road noise, and comfort. Also what non run-flats fit these attributes? Thinking about some good 'ol sticky tires for all-purpose wear. I am not driving in the snow or when the weather gets icy. Need some opinions? Thanks Last edited by Pyscho_Powers; 11-01-2010 at 08:09 PM.. |

1st off rft's are heavy compared to non rft's. Also if you get a leak or slightly puncture it, it is not reccomended to fix. Most shops won't even try to do it. And rft's are expensive! hope that helps.

I have Continental ContiProContact SSRs, and I actually like them. I think a majority of the people here despise RFTs. One thing is certain though, there are not shortage of RFTs v. Non RFTs threads!

Consumer reports on the trade-offs. Google will give you more results. Why I switched was because I wanted to go with a high performance summer tires and a dedicated winter set. Also, as many people have found, run flats are comrpomised by their design in absolute performance. And while new run flats are as good or better than old high performance tires, when compared with conventional high performance tires of the same make, they are not as good. Edmunds found this out comparing Pilot Sports run flats with non-runflats here (though they claim the wet traction difference was by design): http://blogs.edmunds.com/strategies/...rformance.html

If you want a good winter performance tire, I'd recommend the Dunlop Wintersport M3 or D3. For summer, lots of folk seem to like the Michelin PS2 (also available in RFT) or the Conti DW. And for an excellent all season tire, I replaced my OEM RFTs on my 128i with Conti DWS and have been very happy with them. And IMHO, the main difference between comparable (i.e. performance, touring, winter, etc.) RFTS and non runflats is the non runflats' softer ride, larger selection and significantly lower price.

I like the precision of RFTs. Standard tires are too soft in the sidewall and claw quite a bit. I realized this after the switch. If you're going to switch to regular tires, go for a really sticky setup or you'll notice the flex even more.

1) On my M3 I had Michelin High Performance Tires for the Summer and a winter wheel set 18"x8 also with Michelin winter tires (no spare in the M3 only a compressor to pump air plugged into the cigarette lighter - never used it). 2) On my Z3 I have the Bridgestone RFT in my opinion they suck and actually again in my humble opinion caused 2 rear wheel cracks after only 18,000 KM (~11,000 Miles). One wheel replaced by BMW the other one I am still working on to get my money back. Bottom line My winter set is going on the car now yes you guessed it with Performance Michelin Winter tires. When the summer wheels (Type 296) go back on the car they also will have Michelin Performance tires and yes I will carry a BMW portable compressor in the trunk just like I did with my M3. RFT ,,,, bw gone! here you go my 2 cents, hope it helps PS my wife's car also has Michelin on both the summer and winter sets

Just took off my oem 17 with rft... Now running oem 18 on non rft...
What a difference in ride quality especially hitting bumps. Now just got to worry about a spare. |

wet/dry traction and noise are the same. comfort level on non-rft is MUCH better. Michelins and Contis are probably the best tire (summer tires for summer use), but in my opinion they are way too overpriced compared to Korean brand tires. I am happy with my Hankook V12 for $550 that i paid for them

Of course, in the almost 20 years I've been driving I've never had a flat tire. It figures in the car with no spare, that's when it might happen. lol
