Looking to extend Mileage and lower RPM 83KZ1100

90 is as tall as you can get. 150 is too wide I believe.

The RPM will drop by whatever percentage increase in diameter the larger tire has. I can almost guarantee it could not be more than a couple of percent change.

I actually meant 140 , tire.. Dam phone keyboard.. But I thought the same thing the difference would be almost nothing.. But figured I'd ask.
