Changing tire size
Cant wait to see faces of SUV drivers You're right, there is no comparison. From the Oregon department of Energy: The cost of producing ethanol varies with the cost of the feedstock used and the scale of production. Approximately 85 percent... Yes, no, maybe. Your 'perceived' mileage will go down because of the increase in diameter, but the actual mileage might go up depending on your gearing. I went up 2" and my mileage stayed almost exactly the same 'if' I forget I have a 5th gear or overdrive. If I use overdrive, my rpm are too low so the engine lugs and just drinks gas. If I stay in 4th, my mileage stays virtually the same as before which is a respectable 23 US mpg in my CJ7. If my gearing had of been slightly different or if I re-geared, my 5th might still be useful and my mileage might have gone up but... The manufacturers seem to match tires and gearing to get the best mileage and power. Mike 86-00 CJ7 Laredo, 33x9.5 BFG Muds, 'glbutt nose to tail in '00 88 Cherokee 235 BFG AT's d745
