Tire Circumference

2409 Views 9 Replies 8 Participants Last post by  mrcaptainbob
I have a '74 Wheel Horse B 80 that has a snowblower on it. Now in '74 the B 80 only had a 4 speed on it. In an effort to slow it down, I thought I would put some 22x7.50x12 tires on it in place of the 23s. Then I measured the circumference of the tires. The 22s are only 1 3/8" smaller than the others. This isn't going to make much difference in speed, is it?

I've got an 8 speed that I will put in it next year, but don't have time right now.

22 vs 23 diameter

(23-22)/23 = .043, which is less than 5% difference.
