Wheel Width Advice

I am going to buy M6 reps in 19" but am going to stick with 225 front and 255 rears. Some vendors have advised that they think 225 on 8.5 and 255 on 9.5 will be too stretched but looking at the AC SChnitzer site I see that they list many times these very same fitments for their wheels.

Why do ACS list these as Ok and yet some vendors say not to go with these sizes? I am definitely not going the usual 235 and 265 route as I have done that before and it changed my gearing in a big way.

Comments invited please.

Both parties are correct, it's simply a matter of interpretation. Below is link that will hopefully answer your questions:

http://www.tirerack.com/tires/Spec.j...YR9RE050AXLRFT

The M6 rep vendors are saying that the sizing you want will look stretched. They are absolutely correct. But will they fit? Yes, they will. If you look at the 225-35-19 size tire, it will fit a rim width range of 7.5-9". The 255-30-19 size tire will fit a rim width range of 8.5-9.5". This is the reason why ACS says it's OK to use the following tire sizes.

For the best "fit", you would want to use the measuring rim width that the tire was designed around.

I think it up to you what you want. I remember running 255 on some 8.5 rims and the tire was straight. its a one inch diff. I dont see it looking that weird or being unsafe. IMO

It looks weird. The rim appears to stick out beyond the tire.

You could run 225 and 255 on 19s staggered. However, like others have said, the tires will pretty much be stretched out. If you look at what 1WickedE90's posted, 225 will fit 8.5 just fine without being too stretched. But with 255 on 9.5" wheels, you're at the limit of what the tires can be stretched out to. Thus you could run those sizes, but I would personally go with 235 front and 265 rear.

hahah I found a thread with two images, one front and one rear, that you're looking for.. You made that thread... lol here you go:

http://www.e90post.com/forums/showth...hlight=255+9.5

Just in case you were wondering, the offset doesn't matter about the wheel and tire setup. Those are 225 on 8.5 and 255 on 10. Although it's 10" in the rear, you can see from the front, that's pretty much how the rear will look as well. If you're okay with that look, then you can get that setup

Thanks James. I wqs wanting pictures that show just how stretched the tyres are.

Does anyone offer 9j wheels?

What difference would going non staggered ie 8.5j all round, make to the handling of the car?

I really want to order these asap but will not be going 235 and 265.
