Does anyone know if you change your tires to a larger size, ie 28" from stock 26", if you have to modify the clutch due the the effective gearing change to larger tires. Or does 2" have no effect on the gearing. I had a old truck that I went from 33" to 35" tires and it made the transmission have to shift alot to compensate when going uphill. Once I changed out the rearend gearing to 4:11's the problem was solved. Any ideas?
