On our rear Goodyear 26" Front Runner, I measured rear tire circumference = 81.5",
I calculated front circumference: 3.14 * 26 = 81.64"
calculated is close to measured = good!
On our front Goodyear 28" Front Runner, I measured rear tire circumference = 90.0",
Then I calculated front circumference: 3.14 * 28 = 87.92"
2" different than measured = huh???
I will use circumference numbers for a % tire slip display I am still considering for our lil Lakester, so I don't like the discrepancy.
Has anyone actually put a tape measure on 26" & 28" Front Runners???
