Gas Milage/wear/ride difference in these two tires?

[Peytons_Titan08]

Looking to get one of the following:
33x12.5x18 Toyo Open Country M/T
325/65/18 Open Country A/T

Is the gas milage that different? What about ride and wear? Thanks

Not sure about the gas mileage difference, but you should get around 40k miles out of both sets of tires. And as for the ride difference, it' not bad at all, I'd say the difference between the two would be equivelent to the difference between going from stock tires to ATs at the most.

There will be a decent difference in gas mileage since one is a 33 and the other a 35, and the 325 is 13" wide as well.

Toyo M/T 33x12.5R18LT 33.0" diameter 75 lbs.
Toyo AT LT325/65R18 121R D/8 34.5" dia. 75 lbs.

As far as gas mileage, since they are the same weight, that's a push unless you went with wider/heavier rims for the 325s.The larger diameter of the 325 will raise your overall gearing. In theory this might actually improve your gas mileage, but with a Titan, it can also lead to torque convert not locking when it should, and later shifting, which would use more gas, and the larger diameter gives you less apparent power.

For an 18" rim and a 33" Toyo AT, I'd get the LT285/65R18 125S E/10, only 57 lbs, and 32.5" diameter, or a LT275/70R18 125S E/10, at 55 lbs, and 33.1" diameter.

For the Toyo M/T a LT275/70R18 125P E/10 at 66 lbs. and 33.6" would be better, although still a little heavy.

I have Toyo M/Ts in a 73 lbs. 33.5" diameter and they are definitely not as smooth or as quick at acceleration as my aftermarket, 58 lbs. 32.8" dia. BFG AT KOs were. Plus I lost a little bit over 1 mpg compared to the KOs, (2 mpg compared to stock 44lbs. 33s).
