Default Re: e46 M3 Tire Sizing Thread

Just grabed some te37s from one of the other forums. (F) 18x9.5 and (R) 18x10.5
I'm thinking about going with PSS (F) 245/40 (R) 275/35. Let me know if I'm on the right track. Thanks.

So.. the thread lists an 8.5" rim as an acceptable width to run for a 225/45r18 tire, but reading through googled posts, generally it is said that this combo is stretching it a bit?

Am confused..

225 is a little narrow for an 8.5. But stretch, in this situation, is a word used loosely. Google image it, you'll see.

HEy guys,

Great thread; Basically what I've taken from this is to to achieve a non-rubbing, ' M-like' and over steer prone set up the following sizes should be ideal:

19 x 8.5 et 35, 235/35/19

19 x 9.5 et 22 265/30/19

(apex ps-7)

Anyone running this here?

gotcha thanks. It is a bit narrow..

Is there -any- aftermarket wheel that is 8 and 9" wide? All the various wheel choices, and nothing in stock size?

how about all rears all around? 255/40/18 all around

Would also like to know if a 245/40 and 275/35 is a good combo, more for track use

According to the info on the first page of this thread, that works well. That said, most would prefer a square setup for track use.

If you're doing a track setup, square makes sense so you can rotate them and get more life out of them.

Question Re: e46 M3 Tire Sizing Thread

The biggest differences are between those sizes, 225 to 235 or 255 to 265. This is because you need to go a sidewall ratio (e.g., 34, 40 ,45) lower to accommodate the increase in width.

If you only go from a 225 to a 235, you're only going 10mm wider but losing a lot in diameter that is not made up by that increase in width.

Going from 225 to 255 makes sense (mathematically too) because the decrease in sidewall (45 to 40 for 18" rims) is made up by the 30mm increase in width that makes the overall diameter between a 225/45 tire and a 255/40 the same (basically).

235/265 combo is very fast, the CSL runs it. It's not comfortable, not much cushining, but the car will be a tad faster.

245/275 is more popular because it's more rubber (for both width and comfort), but still a tad faster than stock 225/255.

255/285 is a good combo for those with turbos or s/c s who need the traction because of the extra power. A stock or close to M3 with 255/285 would feel sluggish.

I think the problem for people is understanding that 235 is not bigger than 225. Yes 235 is a bigger number, but matched with the 40 sidewall compared to the 45 sidewall that the 225 uses, it's a smaller tire.

I haven't even mentioned what different combos can do to DSC and speedometer, but Ian addressed those in the OP which you should read.

Hi there.

I wanna ask..
I have 4 apex arc-8s 9.5 ET35 and a was thinking of putting a 1.2 spacer rear.
Is it bad to put staggered tires on square set up?
I like the concave of the 9.5s that's why I bought them like this. I was thinking of putting a wide stretching 235/40 front and 265/35 rear.
Don't want the 275 rear with 245 front.
I don't know if I can do 245/40 f & 265/35 rear..???
I don't track the car it's only for weekends and street use.
What do you suggest?
Thank you for your time
