Tire and MPG question

For the guys who upgraded from stock 245/75/16 to 265/75/16, how much of a hit did your mpg take?

I know that tire weight is a big factor, but how much mpg can i expect to lose going from 245 to 265s (32lbs/tire to 45lbs/tire)?

This tire in the p rating is only 41 lbs so you will be fine

http://www.treaddepot.com/tire/352290.html

Of course if you go with an lt or load range e it will be heavier

If your worried about weight you can also look at the cooper at3 which also comes w a treadwear warranty and is only 38lbs

http://www.treaddepot.com/tire/90000002692.html

I run this tire went with this due to the weight and treadwear warranty.

Both are great tires


I would go with the p rated version and you shouldn't loose much at all

Just picked up a set of A/T 2 a few weeks ago so far I'm very happy with them. they are quiet on the hwy and only noticed a small decrease in Mpg but I went from 265/75 to a 285/75R16 LT.

245 to 265 will cost you 1 or 2 mpg. My 265x75R16 are 11 lbs heavier than my 245x75R16 and I lost 2 mpg. I just switched back to the lighter tires since I do mostly highway.

Thanks for the info. What tires were you running (245s and 265s)?

I went from stock 265/75/16 Dunlops on steel wheels, to 265/70/17 Hankook Dynapros (P) onto Toyota alloys on my 2013 4 cly. MT 4X4. So far (haven't been through a full tank yet) it seems like a good 3-4 mpg hit. Truck is quite sluggish up hills and on mountain roads... but, again, it's a 4 cyl and was a bit sluggish to begin with. If it were my daily driver, I would certainly return it to a 245 tire size (not the Dunlops).

I didn't even take a hit like that going to 285/65r18

Yeah, probably has more to do with my 4 cyl. and the drive up to my mountain cabin... doubt it would be as bad with a regular commute.
