Confusion about Regearing??

[Rob Slade]

Currently I am running a 31" super swamper with 3.73 gears on my 1995 X. Since I have the '95, I have the older OHV engine with the 160 horsepower. I have noticed a signifigant decrease in gas mileage from my old set of 30" tires. My question is, will I see any advantages in going with a 4.10 gear in terms of gas milage? Since the stock tires were 235/75/15's with a 3.73 gear ratio, the current actual gear ratio is about a 3.55 with the 31" tires (according to www.4lo.com). Would the 4.10 gears with the 31" tires equal the power and mileage of the 3.73 gears with the old 235/75/15's?? Sorry if this sounds confusing.

The way you are now, you should be getting a little better highway mileage than before. The city may be lower though. If you havent had your speedo gear changed to match your new gears and tires then you may be getting better mileage than your miles are indicating. Your new tires could be a lot heavier than the old ones, which would use more fuel. Lots of factors at work.
