Tyres... How Wide?

[arm85]

Hey guys its about time to replace my front tyres now i love the look of really wide tryes, ATM i have 255/35/18 on the rear, can i put 265/35/18 or even275/35/18 on the rear will they be too wide or will the 255's on the front be too wide for the fronts? and more importantly will it negatively affect the handling?

Also on the front at the moment the profile is 40 will it matter if i swap my rears the profile will be 35? thanks any imput would be appreciated.

Thanks

what size rim do you have? get hold of a tyre sizing chart or speak to a tyre shop, ask them what the limit is for width on that size rim.

there is a rule of thumb that suggests you should put the narrowest recommended tyre possible onto a rim if you want it to handle as it stiffens the sidewalls.

but you've said you want the look so if you can put up with going slower, feeling more bumps, tramlining and the extra cost go right ahead.

just j/k - it's up to you but there is a down side to wide tyres.

as for the profile, as long as the rolling diameter (use the tyre size chart to find out) is the same it makes no difference. i think there is a legal tolerance with rolling diameter - about 15mm from stock from memory.

as for fitting your car it depends on the offset of the wheel, ride height etc do a search and you'll prob find a discussion on what fits an R33.

sorry yeah rims are 18 x 9 all round so any one got an idea on what is the widest i could go on front and rear without affecting the handling

I reccomend 235/40/18 on the front and 265/35/18 on the rear although 9" is a little wide for the front.
