For 'street driving' you're fine. Its better to have a stickier tire in the rear than the front (if you have to have unmatched tires) in my opinion as I'd rather push a little than spin unintentionally.. not that either should happen so long as you don't drive like a maniac.

Edit: FYI though.. R888's are not a general purpose tire.. unless you're putting down some serious horsepower and really really need it I would avoid that tire as a daily driver tire. They're going to wear fast, and in rain/etc they're pretty slick.. and they likely wont' heat up as fast as your Star Specs so you may have a loose rear end until their warm.

Double Edit: I should also mention that a true r-compound tire generally does not give you much audible feedback. So if you're a guy who throws his car into corners and off/on ramps pretty aggressively and then waits for the squealing before easing up.. you're going to have a bad time as the tire won't make much if any noise before letting go.

Thanks Marcus. Not many know but im in the midst of building my car at the moment (spare block in hand). Im still in the middle of a 6766 &7168 with a qsv and tubular mani. I want as much traction possible on the street and the r888's fit the bill for the rear. I wont be taking corners for the time being as I've had my fun with that already..

For those running 17s in rear I've been informed to try a 11.5 wheel for 315/35/17 and it should alleviate most of the cornering issues

To 95silverM: All of Marcus's post is full accurate information. You would be wise to listen to him.
I dont see that you are FI. Stay with the Star Specs. I am loving my set now on my other car as much if not better than the RE-11's. The Dunlops are great street tires, perfectly suited for any HPDE as well.

Track compound tires can be scary. I have not spun out on my track only BFG R-1's (yet). They barely make a sound when they are stressed. You have to really concentrate hard and pay attention to the smallest things when you are pressing competition compounds to their limits. They give almost no warning when they are going to loose grip.

Use R compound in the street only if it's absolutely necessary.

Bumping this thread back to life.

I'm currently in the market for 18s.. Most likely Apex Arc-8. I'll be going with 18x9.5 et35 up front. My question for you tire/wheel gurus is what size in the rear? 18x10 et25 or 18x10.5 et27?

I plan on running 255/35/18 and 285/35/18 front and back respectively. Or 265/295 depending on my tire choice and what's available. I would like to run Nitto NT05 but 255 is not available. So I would be left to run 265/285.

Anyways, what are your guys recommendations for the rears? My fenders are cut and sealed so I will not have to do any fender mods. Should I go with 10.5" just in case I decide to go with 295 in the future? I know m5chas ran 295 with a 10" wheel. Feel free to chime in

You and I are pretty much in the same boat in terms of finalizing what tire size to run on 18 inch wheels. I also ended up with the same debate of 255/285 or 265/295 and after seeing 295's on a M3 it pretty much sealed the deal on which rear tire size to go with especially with Boost! I'm currently running an 18x11" wheel and awaiting my tires so I'll definitely have some feed back soon on that tire size.

What's your offset on the 11" wheel? I wouldn't mind running 295 but I don't want to run that much neg camber to make it fit with a 10.5" wheel

Edit: nvm found your post above with your wheel specs

This has alot of good info...http://www.m3forum.net/m3forum/showthread.php?t=428513
I'm still undecided atm what I'm going to get but most likely ARC8's 18x9.5et35 up front and a 18x10.5et27 rear with NT05 265/35/18front and 285/35/18 rear ...295's have my interest.

Thanks cw! Found the thread last night. May have to try 265/285 combo with same wheel specs as you mentioned.

It's funny the 285 is cheaper than the 265 on nt05 from Discount Tire Direct

Honestly I'm not sure of my offset i bought my wheels a while ago and been through a few sets but never gave these up. I'm getting them refinished so once I get them back I'll report back my offset. As a side note onlinetires.com has the nt05's cheaper than discounttire

Got me confused with someone else...I have been limited with my 380mm brembos...won't fit on the 18" APEX ARC8's and I dislike the EC-7's. So sooner or later I'm going to be getting new 355mm brakes and ARC8's.

you might want to keep front rotors 380 mm / 19" wheels
rear rotors 355 mm / 18 " wheels


I dont think a 11" will fit under e46 M3.

Cw, I'll be getting rid of my oems once I get arcs. Do you need tires for the mean time before you go 18s? NT05s. In your specs
