Yup, with the right sized tyres :)
Run a 245 on the rear, and they will fit with a roll and slight pull, possibly even a 255.
Fronts will need more like a 225 and a couple of degrees to tuck under, and a roll and pull :)

if you put 42 et you can run 265 with no rubbing. so 255 on +30 is fine.  what wheels btw

Maths is slightly off there dude.

et42 with a 265 sits about 7mm further in than a 255 on a +30, the tyre is spread over the whole rim so for width changes you need to half the difference in tyre width as it changes at both edges :)

So 265 et 42 is roughly equal postiioning wise at the edge of the tread to  (42 - ((265-255)/2)) =  255 et 37 :) Make sense?

But then it depends on the shape of the tyre wall too - some are more \'rounded\' than others.

To the OP: You will have to do archwork, but it should be restricted to just a roll and possible small pull.
