ok I think I get it.

Man I should have paid more attention in math class. So is there an area where the 1st set of measurements ends in millimeters, and inch measurements begin?

For example:

285/75r16
(then next size up is)
33/11.5/16

Oh...... don't you love the new guys. <img src="/forums/images/graemlins/scared.gif" alt="" />

Tks again,
