cool thanks

use a tyre calculator like the one at www.tires.com to figure out what size of tyre u need.

the reason why people get lower sidewalls is due to the use of a larger rim... but want to maintain stock overall diameter so as not to require a speedometer adjustment.


it's called "plus sizing"

here is the general idea of plus sizing...

Plus 1:
Increase section width by 10mm
Decrease aspect ratio by 10 points
Increase rim diameter by 1 inch

Plus 2:
Increase section width by 20mm
Decrease aspect ratio by 20 points
Increase rim diameter by 2 inches

as the pattern goes, you can figure out what you need for plus 3 and plus 4 fittings...
