I doubt you'll notice a great deal of difference tbh... but it'll help make your speedo more accurate fitting wheels/tyres that dont reduce/increase the rolling radius of the wheel a great deal.

 

so 275s wont rub the arches then .theres not much difference in price between 40 and 35

I have 285 30s on my 18s and get no rubbing..( I have stock UK suspension) depends on the offset and right height tbh, I know Kev O. got rubbing on his arches at those sizes.

 

cheers m8 thanks for the info

only thing is ive have two nearly new 40 profile for the 8.5 fronts will this make any difference

If your speedo is like most of us it's already about 10% over anyway. Upping the size would go partway to compensating.

 

Going from /35 to /40 will up your speedo by 4.2% taking out some of the error...

if the question was , which pair to go for I must say I really liked the patterns on the new se but as I never heard of them I'd go for the used mich ones ;)

 

265 is a bit narrow for the rear, Im ruuning on 285/35/18s and I'd say 275s are the best hassle free option if you dont want to have probs with rubbing etc ;)
