Hi, if I go up from 32x11.5x15's to 33x12.5x15, will it make a significant difference to my gearing?
Anything will help, but what sort of change in revs can I expect if I'm currently doing 2,300rpm @ 110km/h?
Cheers

measure the circumfurence of each tire and use this formula
(circumfirence of 32" tire) divided by (circ of 33" tire) times 2300
this will tell you the RPM at 110 kph

V8,
I think you'll probably find they'll "tram line" a bit more which can get annoying. I recently went from 35x12.5's to the 33x12.5 and had hoped this feeling would go away but nope, so figured it has to be because of the width. Did wheel alignment still no change. Tyre bloke told me should have gone for the 32x11.5's. Don't understand how that 1 inch can make all the difference but hey,
Cheers
Matt
