what are your thoughts on running 285s in rear with stock front fitment?
I'm not sure why mb put 255s on our cars but I'm thinking of just st going max wide I can go on the rears and maybe use a spacer combo for the front to compensate?
only reason i want to keep front stock size is I can't find a tire that has a 25.2 in rolling diameter like the stock rears and found a 285/30/18 that has the same rolling diameter as the stock setup.
say a 12-15mm spacer in front and an 8-10mm out back?
Your going to run a 285 on the stock 9 inch rear?? Yea going to feel squirmy. And then a 10mm spacer to take the stock rear et to 44 with the 285 yea I'm thinking def no. At least not without rubbing
I don't know, you can look up the specs at TireRack on section width and tread width and compare to other tires.
yes u can under specs and u can play with all the different diameters to get the ratio you want.
used it alot for my e55 to get a really tall tire to help put the power down and get it just right in the top of 3rd gear just hitting the end of the 1/4 mile to not shift.
Im running 275's on stock wheels and it is just right. I do feel it is a little more squirmy than 255's though. 265 must be a perfect size for a 9 inch wheel but I personally like a chunkier look.

Right. I know, thanks. That's what I said. I use it all the time to figure out which tires can fit. I was saying that I don't know the answer to your question, and to look it up versus other tires. I think it's a 'normal width' 285 but it depends what you're comparing to, which I have no idea.
Just saying that they fit for me. In answer to the original question.
I ran 285 M/T Street Comp rears on stock 18s for about a year and a half...no spacers...no rub...no issues And I didn't feel that they were any squirmier than stock...

275 MPSS on stock 18s with 2" drop works good no rubbing or anything. Barely a 5mm gap between tire and fender though.
I can vouch for this. I had 18s on my 09. Same rims. When I ran factory rubber size I had a 12mm spacer up front, and a 10mm in the back.
Then, I took the spacers off, moved the 255s to the front and put 275s on the rear. Looked like a hot damn, gripped up much better too. Even though I had LSD when pulling out of one particular corner at my local track I always had to lay off a bit or I was just shredding. With the 275s it hooked up much better.
