hi everyone, im swapping my tyres some some ultra ssessantas, im going with 235/35/19 265/30/19, i believe alot of peeps are running 245/275. just wanted to treble check that the 245/275 definatly dont rub at all, has anyone used these sizes at the track where extreme cornering is envolved?? no rubbing in those circumstances either? ive currently go 235/265 combo and it seems as big as youd want to go but if i can get away with the larger setup then ill go for that.

someone please chime in, ive done a search and theirs alot of recommendation but ive seen nothing relating to using these wider tyres on track?

so basically to cut my b/s short will the wider setup rub in the extremes of use?

cheers peeps
 
I'm on 275/30/19 rear, and swapped my fronts today to 235/35/19. No rubbing whatsoever. Other are running 245 fronts or up to 285 rear, apparently with no problems.
 
cheers shunt, hoping some more people will chime in here, before i go for the larger size is just want to be 100% possitive the 245/275 setup wont rub at the extremes of usage (track usage), this is holding me up from ordering my tyres!

anyone else?
 
I ran 275/30 and 245/35 PS2's for a week and thought that the 275's ruined the high speed handling. So much so that I took the 275's off and sold them. There were, however, no issues with rubbing. 265/30 and 235/35 is a good combination, I would think the 265's would work well with the 245's as well but I haven't tried it personally.
 
think im going to stick with the orginal CSL sizes, which is 235/35/19 & 265/30/19, i suppose if its good enough for the csl its good enough for me!

Just remember that the 265 rear will not protect the tyre at all from kerbing - doesn't matter how careful you are YOU WILL scrape them at some point.
 
dont wana tempt fate but im very careful when it comes to kerbing, more to the point, because this is my w/e toy i never leave it anywhere by kerbs, my Daily driver does those tasks!!

bmw put these tyre sizes on the CSL so they must be optimal for the rim if you get me!

I'm on 245/35 and 275/30 and have never had any rubbing issues. The only time mines been on the track was at vmax but you can push the car really hard on the bends and it's fine. The 235/265 combo really look a bit stretched over the wheels when i've seen them.
 
235/265 here, but I do get rubbing on the front inner arches (well, until I modified them). However, that's because the car is wound down so low on the Clubsport coilovers to reduce the centre of gravity...

Sounds like 245/275 will be fine with moderate lowering and/or standard suspension. :)
 
235/265 for me. Can't see much benefit on going bigger other than more chance of collecting a nail on the road. Thought about 275 rears to give me more rear grip but never did it and stayed with the original CSL sizes.
 
As above. i'd stick with stock sizing.

that said most the CSL boys run the rears on the front!!! 265 all round! Seen it at the ring numerous times. looks shite!
 
I'd recommend swapping the tyres left to right after a few thousand miles (or wherever you think they've used half their tread) as you'll probably find that due to the amount of negative camber the cars run on the rear, you'll have 0mm on the inside of the tyre and 4mm on the outside.

With asymetric tyres you have to flip the tyre on each rim, but with directionals you can simply swap the wheels from side to side - and save £7.50 a wheel too :thumbsup:

I'm still planning on trying 275s on the rear & 245s on the front - on original 18" wheels of course.

directionals would then be pointing the wrong way surely :?

reversing fast isnt much fun...

Doh, of course. So you still have to flip them on the rims, then swap them left-to-right. Doesn't save £7.50 a corner then :thumbsdown:
 
I run 245/35 and 255/35.

More grip at the front - less at the rear and circumferences almost identical to the Z4M OE (gearing correct).
