e46 M3 Tire Sizing Thread

[liam821]

This may have been asked already, but has anyone run 285/35-18 on a 18x10 et25 rear wheel? With stock alignment and minimal lowering will it fit?

I'd get a second opinion, but it should fit.

So I'm running stock 19" Style 67's (all stock everything suspension wise, except old tires which are 235/265 Conti DWS06 All Season)... and it's new tire time... old not mileage due to life (and Covid) interference... I may just roll the dice and try to get my money out of these shoes (if I have 15k on them since 2016 I'd be shocked)...

But I'm thinking about sizes... it seems like I can go 235/275 and be at like 80.0 (8" front) and 80.1 (9.5" rear) in rolling diameter according to the OP's stats and calculations...

liam821 Have I read that correctly? If I'm not going to see tons of miles on the tires I may as well fully utilize the tread out back, is my reasoning... I've since put ECU and TCU tunes (and probably new rear struts) on the car, which should help.

Any thoughts? Thanks Gents,

maw1124 Sorry, just saw this, I think the reason why the first page recommends a 235/265 is it keeps the stock stagger ratio. I'd think running a really big rear tire and a small front 235/275 would cause understeer at the limit.

Yes I ran the 359 wheels. I ran 255/35 in the front and 285/30 in the back. It was a very flush setup It rubbed very little in the back but not much. The fronts I had to camber in a little bit.

Cool. THANKS. I wonder how a 245/40-19 275/35 would fit. Not as wide, but slightly taller.

Have you tried this setup yet? I really want the 359m black wheels for my car. Id be less aggressive with the tire size though. 245/275 would be the biggest. I haven’t been able to get a straight answer as to whether or not they’d actually fit.

I knew a local forum member running a 275/30 PSS tire on a 19x10 ET27 wheel lowered on Bilstein coilovers with stockish camber, and the paint on the inner rear fender lip was partially rubbed off. Pretty sure an ET25 with a 285 will rub unless it has a good amount of camber.

I'm currently on 19x9 et28 with 245/35 and 19x9.5 et19 with 265/35 and on willtheyfit.com the only difference for the rear was the inset. I have zero rub.

Anyone know if I will have to roll the fenders with 359M wheels in this configuration? lowered on coilovers

I think you'll find that the Michelin's are the best tire you can put on the e46m3, period. If you want more performance, get Cup 2s, but for the best all-around not going to drive in the snow Pilot Sport 4Ss can't really be beaten.

Great info Liam! I finally signed up for the new forum, great to see you (virtually). And I love my Goodyear Eagle f1's as well, but Michellin's are great.

Do you happen to have pic of what it looks like?

I took a few, I hope it helps.

I have 255/40 and they look square, no stretch. 255 is the max recommended width for an 8.5 wheel. Plenty of e82 people use 255/35 size with their rear OE wheels which are 8.5

Anyone running 255/35-18 0n 18 x 8.5?
What would the tire look on the wheel?
