What's your fuel mileage on 33s?

I lifted my DD and put on 33-12.50-15s. I only noticed a loss of about 2.6 mpg. 16.9 mpg down from 19.5mpg. What are you guys running 33s get?

I'm sure something isn't right and am ruling things out as I can.

Re: What's your fuel mileage on 33s?

I guess I should say I'm running a manual and axles from an automatic, so 3.55 gears. I did my mileage test never using 5th gear. This next tank I will use 5th when I can. Also my mileage was a mixture of in-town and county highways where the speed limit is 50.

13-14 in town and 18-19 hwy. 285/75-16 and 4.10s. I'd do 65 on hwy. Any faster and the mileage plummets. Don't expect good mileage trying to keep 80mph. Also how correct is your speedo?

Switching to 355s and 33in tires it puts my speedo ALMOST exactly where it should be, according to my GPS going 50 my speedo says 52

Re: What's your fuel mileage on 33s?

I got 15-16 driving from WA to CA all highway at about 65mph. Although I was towing a small trailer with my motorcycle on it and the back loaded with stuff (I am also loaded down with winch/bumpers/tire carrier/full size spare). So may have been slightly better unloaded. 2000 4.56 33s with speedo corrected.

Re: What's your fuel mileage on 33s?

I calculate by topping off tank, estimating mileage based on google maps between gas stations , and then top off again, and divide. I dont trust the speedo, etc. I dont bother for short drives, but anything over 50 miles, I do that.

I was getting about 12-14 mixed with 4.10s and a 5 speed and it wasn't near enough gear.
