(yeah) Hello Michael, I run a 3.0 rear axle with 235.60.15 (26") rear tires, runs about 3000 RPM at 70 and works well with no overdrive. Just wish I had a taller 2nd gear... When I commute regularly I get about 18-19 mpg. I have a 2.8 gear set I may try but for now it works. Remember I have a short rear tire, better to choose a shorter and lighter tire and adjust your gear ratio to match instead if cramming a large heavy tire in there.
