Hi

A quick question have a set of 8" x 16" alloys to swop with the 7" X 16" ones on my P38. The problem is my tyres are new 235x70x16, and the knackered ones on the 8" rims are 255x65x16.

Will my tyres be okay ?

Cheers Ian

Maths gentlemen Maths 8" = 25.4x8 = 203.2mm or 20.32cm which gives you rim width.

285/75 = 285/4 x3 to give you tyre width so 285/4= 71.25x 3 = 213.75 or 21.375cm tyre width. They'll fit but I think I'd fit wider tyres as they'll look a bit weird having the rim almost as fat as the tyre..

wait, 285 is the tyre width in mm anyway, isnt it? so the rims will be 20.32cm wide, and the tyres will be 28.5cm wide, wont they?
