Just bought some wheels for my M37x awd. 20x10.5 +25 all around. I know fitment might be tight but am I going to be fine with stock size tires (245/40/20) ? Or i should go with smaller tires lile maybe 255/35/20?
Thanks for your help

Hey man, look in the FAQ in my sig for the wheel size thread (towards the top). There is a site there you can use to compare the stock size (wheels and tires) with the sizes you're thinking of running and it'll break it down for you on what will change in terms of fitment. Great site.

I am interested in this as well. I would prefer to run a little wider tire maybe 275 wide instead of 245. Has anyone attempted to run the OP wheel specs on their M?

just put my tires on. Front pokes out a little but manageable. Rear seems to be fine. Coilovers are going on soon. I'll post some pics shortly.

If you're going to run 275/40, I would suggest less aggressive wheels

You should just post photos for now just so we get an idea how it looks. :)

Personally i want to run a thicker and less stretch of a tire so it will help with the road imperfections and also reduce the likelihood of a tire failure.

Are those CV7's? Looks amazing! Is there a difference in stock offsets or suspension clearance between RWD and AWD? These cars are misleading... I've seen +45 offsets look identical to these +25 :gotme

I am in the market for some aftermarket wheels, I will be lowering my Q with the Eibach springs and using the stock tires 245/40/20. My concern is the wheels I am looking at are 20x9 (like stock) but has a 25mm back spacing vs. the stock at 43mm. Can anyone with experience chime in and let me know if this would look okay, I don't care for my wheels / tires to stick out past the fender. Thanks in advance!

You're gonna be fine. Look at the pics I posted. My wheels are more aggressive and they fit. Go for it
