10.5 rim front

Hey guys, need some wheel advice..

I want to run a square setup of vossen cv5 20 x 10.5 offset 27 all around, the rear fits fine but I'm not sure what I can get away with in the front .. Im also lowered on h&r springs...


Any help would be appreciated ..
Thanks
Vince

haha... I like that

I have seen people run 18 x 10.5" wheels squared with 275/35/18 tires. I don't see how it makes any sense to run 20 x 10.5" wheels square. It's probably possible but your 20" tire sizes are severely limited. A 275/30/20 will be too tall for the front, a 275/25/20 doesn't exist (to my knowledge) and the sidewall would be ridiculously short, a 255/30/20 will be waaaay stretched, a 265/30/20 might work. Overall just a silly pointless endeavor IMO. 20's suck on e9x M3's. The car is not set up for a wheel larger than 19". Porsche 991 and Nissan GTR work with 20's because they are designed for a larger overall diameter tire. Note that the aspect ratio on the 20" wheels put on the above listed cars is equivalent to 19" tire aspect ratio on the M3. There is a loss of performance if the tire sidewall gets too short.

thanks slicer, the reason i asked is because i'm running vossen cv5 20"x9 and i'm using a 17mm spacer in the front to bring it flush to the fender, just by looking at a 17mm spacer it looks like it can accommodate something wider than a 9 width...

you make very good points as to the other components that would stop this setup from working properly..

The car definitely has room for wider wheels (I run 9.5" and 10" front wheels) but when you go with 20's you don't have decent tire options. With 18's or 19's you can run 245's, 255's, 265's. or 275's in the front. With 20" wheels you are pretty much stuck using 245's or 255's. Running really wide wheels with those tire sizes is pointless and in fact I would argue negatively impacts performance. 9" is about as wide as I would go with 255's. 9.5" is ok but unnecessary.

But if looking at 19" wheels, a 10.5 should be able to fit no problem, especially considering the additional tire options? Specifically, a 19x10.5 et15 for the front.

A 10.5" wheel does not fit in the front with "no problem". It's a pointless fitment IMO. What are you trying to achieve? Do you want to be able to tell your friends you fit a 10.5" in the front?
