(z4m) Csl tyres advice please (particuarly track goers)

[Beedub]

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

Extra grip will not necessarily be generated by a tyre that is 10mm wider as it is more to do with chassis geometry than a minimal increase in tyre width. The choice of tyre make is more important than upping the size although if you have your heart set on wider tyres then it is possible to fit 245/275 front and rear. I actually went DOWN to 225 on the front of my Z4MC to try and improve turn in but unfortunately wrecked the car at Castle Coombe before I was able to evaluate the change ( and I also learnt what I have said above after the event so it more than likely would not have made a difference ).
