C55's What size/brand tires for 80-100% traction?
I'm talking about from a dead stop or from a 20mph roll, let's see some reviews? I plan on getting forgestars in 18's, lighter wheels also mean less traction.
the pirelli p-zero's that came with the car were up in smoke when i wanted them to be just by flooring it. on my michelin ps2's, they hardly give. i think they're the best, right before street slicks.
Granted I'm putting out 366 torque to my rear wheels, so they break loose pretty easily.

i'm coming up on a year for my new tires on february 11. my front ps2's look brand new still, but i rears are getting a little low. i think they should be gone again in february (i got new tires for my birthday, february 11
so i'm thinking about getting ps3's in the rear. i get them at dealer cost anyways.

Sure, I changed my suspensions too but the grip is just phenomenal!

ohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh hey i know you! you're the guy that did the full engine swap! yea. anyways. i still think you should've got a blower. but you have what, 440hp? do street slicks. it's the only way you're gonna get what you're looking for.
If not
PS2 or other extreme performance tires should do.. Factory OEM tires are crap and remember, they are old..

If you're on a tighter budget, I would recommend the Dunlop Sport Maxx TT. I chose these as replacements for my summer tires on the C55 after I wore out the PS2's. The track testing from Tire Rack certainly suggested that these tires were pretty damn good for a high performance summer tire. With these tires, I was only 0.3 seconds off my pace at Mosport recently. I was very impressed.
However, for those who want a more "extreme" high performance tire with lots of grip (and less of longevity), you can consider either one of the following: The Dunlop Direzza Sport Z1 Star Spec, or the Bridgestone RE-11.
Last year, I put the Star Specs on my 135i and they were indeed very impressive on the track. Dry grip was phenomenal, and they are "wider" than their track width numbers suggest. This year, I put on the RE-11's, and my laptimes decreased some more on multiple tracks. Both are pretty hardcore, but if you want ultimate grip for a street (non-R compound) tire, they are pretty good bets, in my opinion.
Bottom line: you can't go wrong with the Michelin Pilot Sport PS2's if budget is not an issue. The only negative thing I can say about them is the outer shoulders are relatively soft and wear relatively easily with track duty. In my opinion, the Dunlop Sport Maxx TT has been an excellent replacement tire on my C55 this year, as I have not noticed any signficant difference on the street or the track.
If ultimate grip is what you are after for a street tire, then either the Dunlop Direzza Sport Z1 Star Spec or Bridgestone RE-11 would be awesome. They just have very low tread wear ratings.
My experience only applies to street and lapping on a track/road coarse. I have little experience with drag racing, so take my advice with that perspective.

Been running the dunlop direzza star specs for over a year now and I like them alot.
25 series would be funny looking... saw a Eurovan at Pasco BugJam last weekend that had 20 series tires in the front... there was no sidewall whatsoever.
I get no rubbing at all. I have Mandrus Millenniums 18x8.5 front 18x9.5 in rear they were on the car when I bought it. Not sure of offset, might detail car this weekend, if I do I will see if there is an offset stamped in them.

As far as size. I run 235/40/18 front and have run 265's rear, but the rubbing is too much under full compression to deal with. Yes, I have rolled and modified the fenders as much as you can do without welding and paint. The section width of 265's z stars is just too wide. I went back to 255's yoko's no problem. Again I'm running -1.8 camber all around with 9.5 sl55 22 spoke rears. The rims and tires are actually for sale/trade for stockers with a couple hundred....
as an example proper offset for an 18x8 wheel in the back on a W203 C class is 32 on an SL it is 25
I believe my 18x9.5 are 35 and factory SL 9.5 are 27 I believe
aren't your slk wheels wider in the back? and there's a guy on here with i think o4' sl55 rims (yenno, the ones with tons of spokes) and he has 265's in the back and 245's in the front. it rubs in the front.
