e46 M3 Tire Sizing Thread

[maupineda]

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

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

Hi All...another burning question. The car I’m about to purchase has 285/30/19 Pilot Super Sports(new) on the rear. Am I okay putting 245/35/19 Pilot Sport 4S on the front?

Yes, Super Sports and Sport 4S are within a stone's throw of each other.

Found a post by Apex Race Parts showing 285/30/18 squared on 10" wheels, et33 front and et25 rear. They stated the car was on Ground Control coilovers.

Thanks Liam(EXTREMELY envious of the Phoenix Yellow)...so I’ll be a newbie next week, 02 TiNa, convert, manual w 63K, and will be adding new rubber. So what tire size is your personal recommendation ?

haha thanks! Yeah, like r4dr said, you should figure out the rim width first. Once you get your car let us know.

I'd guess 8.5" front and 10/10.5" rear. But knowing the wheel width is essential to picking what size tire.

Don’t know just yet. Set to look/buy next week. Currently has 245/35/19 front and 285/30/19 rear.

Cup 2s will also wear down before your eyes.

Cb3319 , what width are the wheels?

[Cb3319]

AND wheels are 19” SSR GT3s.

[Cb3319]

Titanium Ag, that is.

Michelin Pilots vs Toyo Proxy XL...any experience?

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.

Ahh - this ruins my idea of putting my old 255 19s rears on my CSL wheels.
