i have an 08 335i coupe with 18 inch runflats--has anyone replaced their run flats with regular tires and noticed any difference in handling--has any one put on wider rims with regular tires and noticed any difference----if so how wide of a rim--thanx
does the ride bother you? just curious Considering BMW dialed in your car's suspension and was designed to work with runflats (as you already know).... you could probably expect a softer ride, and probably 'less-connected' as well, since the sidewalls of a standard tire are not nearly as rigid... just call me "Mr. Obvious"
RunFlats Ditch the Run flats and get Michelin PS 2, Goodyear F1 Asymetric, or Bridgestone RE050A Pole Position - Non run flat Version. There is another tread on this forum (started by SHYATT) with some good information.
Replacing run flats w/BBS CHs+Potenza RE-01Rs So what did you decide to do? My 2007 335Coupe/Sport suspension w/run flat Bridgestones and the 5 spokes looks/feels fine; slightly jiggly but so what.... It's just that the OE 18"ers don't "grab" me. So.... I just received a new set from Tirerack of silver BBS CH's (fronts 18x8.5s; rears 18x10s), w/OE size RE-01Rs, fitted with TPMS sensors; ready to mount. Having trouble bringing myself to fitting them on, even though I can't really send them back. Tire rim bumpers offer less protection = bad. BBS look = good. RE-01Rs = good. The two together = GOOD+. Not worried about using spray goop for nail holes, etc. - have done it before and it simply washes out when you get the tire repaired. Also, BMW sells a jack/tire changing set and one could haul around a mini-emergency spare. Truthfully, I figure if a tire gets destroyed it's going to mean a flatbed trip to the tire store no matter what (I purchased the Tirerack road hazard plan). Wheel sets look terrific...in my garage. Why didn't I buy OE tires for the after market wheels? BMW book says RFTs are not to be repaired, and the price is outrageous in my book...hence my decision to go with RE-01Rs. Fingers crossed no matter what, as here in Northern Virginia potholes are not unknown. Does anyone have this wheel set on your car? Tirerack's "Conner" told me they sell hundreds for BMWs; all with no hassles. Your experience??
i did nothing and will wait till run flats show wear and will replace with goodyear f tires and keep bmw rims
