Ok the math is killing me to but just because I needed to figuer it all out so here it is. And yes I have a touch of OCD at times
32's: Cir=100.48" Rev. per. mile=630.57
33's: Cir=103.62" Rev. per. mile=611.46
35's: Cir=109.90" Rev. per. mile=576.52
and 1 mile = 63360"
So 33's will: Get you 1 extra mile for every 32 mile compared to 32's
and 35's will: Get you 1 extra mile for every 10.67 miles compared to 32's
and 1 extra mile for every 16.5 miles compared to 33's
sorry but I had to redo the math for my own sanity. lol...
