My Ride: 2008 535xi
I have a 2008 535xi with 18" staggered wheels with runflats. I need new rears, but the fronts are OK. My plan is to go to all non runflats. However, now I only need rears. I am going to get Yokohama S-Drives. My question is this: Is is a big deal (safety, etc) for me to have the Yokohama S-Drives (non-runflats) on the back, and the Dunlop runflats on the front? I really dont want to buy 4 tires if I only need 2 at the moment. I would imagine that I will replace the fronts some time in the middle of next year. 17" winters wheels and tires are going on the car in 2 months, so winter performance is not a concern of mine.
Thanks.
Thanks.

Why not? It's your car. Whether you will be pleased with the result is questionable.

to answer your question though, i dont see a problem, providing you are running them F/F or R/R. not placing one tire in the front, one tire in the back. visual asthetics (sp?) will be the only downside.

I was in the same position last week, and I could get just the two matching rears, RFT, for $840.
I was able to get all four non RF, for $925.
Kinda a no brainer.

Conventional wisdom says not to use two different tire types on the same axel, which you are not. As long as you are not really pushing the car you should be okay.

You're mixing tires (even front to rear) with very different handling characteristics -- IMHO the result under normal driving conditions isn't likely to be noticeable ... BUT, I suspect that spirited driving and emergency handling will be compromised.
I wouldn't recommend it!

Member v_therussian does mix RFTs and nonRFTs with RFTs in front and non-RFTs in back. He has seem to manage OK even when driving hard in the twisties on our meets. That is probably a result of the fact that he's a very good driver.
But I believe that if he were to keep his ride (he's selling it) he would be wanting non-RFTs in the front.
