Ride height and different tire sizes: Difference between revisions

Comments from people who have changed tire sizes:

*I ran a 100-80 and 130-90 (instead of 100-80 and 120-80) and the difference in new tire vs worn tire took more getting used to than the ~~8mm~~ height difference ~~(in the rear)~~. Same when I switched from that to a 100-90 front from the 100-80. Spend a few miles getting used to it and you will be fine.

*I rode with a 100/80 front and a BT45 130/90 rear, then a 100/90 front... not a whole lot of difference that couldn't be attributed to the new tire feeling IMO.

Line 28:

But wait, you say; there are sidewalls on the top and bottom of the tire. This is immaterial for calculating ride height, as the extra diameter above the axle does not affect the height of the bike. Only the distance from the axle to the ground affects the change in ride height.

Remember also that tire sizing is not an exact science, even between different tires from the same manufacturer. So, a 120-width tire may be 118mm or 123mm. The few millimeters won't make any noticeable difference.
