Why are the 335i coupe's stock front tires 8 inches wide but the rear tires are 8.5 inches wide?
Does this matter when I order the 18 inch M6 replica rims? Thanks.

well, the short answer is typically more rubber on the road = more grip, and most people want that with a car with as much power as the 335. most people think that it also gives the car an aggressive look, as opposed to have 8" all the way around. also, the larger tires you get up front, the more the car tends to tramline, ie the more the car will follow the grooves in the road.

the thing you should be aware of is the size of the m6 replicas and wether or not you need to get spacers, roll your fenders, etc. someone else might be more qualified to tell you about that.

Also a 335i oversteers a lot more with the same width tyre on the back as the front, putting a wider on the rear reduces oversteer a fair bit.

Good move getting 18's living in NO. The streets are horrible. I have 19" M6 reps on my 335 but i live on the Northshore an usually take my TL into the city.

The tires in the rear are wider, 255 vs 225 for the front, hence the wider rear rim. Most M6 reps (in 18") are not staggered and are only 8" wide which makes it hard to run a 255 rear (can do 235 and maybe even 245) but I have found one place in Montreal that has them in staggered sets and a place in Cali that has them in 8.5" wide (you can probably do a 255 rear on the 8.5" wide one but not ideal). And on a 335xi, the reason you go staggered is for a more aggressive look, on a 335i, it's that and to reduce to oversteer a bit.

Yeah I would get reps if they were 8.5" wide, you can then go 225 up front and 255 on the rear no problem at all. This is what Hartge, ACS and most of the aftermarket companies use.

Thanks to all!
