I have looked at that, but it seems tires any larger in diameter than the OEMs (33inch) weigh another 10-15# each!? If I had the (scarcely) available 6-speed manual, taller tires would certainly help, as 6th in the manual equals 4th in my automatic. A manual swap is still on the to-do list.
Do you slip-shift? That will save you clutch wear. I only use(d) the clutch when starting and stopping. The rest of the shifts I just modulated my right foot to hit the next gear...
I've been reading your topper project. Nice work!
