Hey guys, I purchased a 2012 Silverado z71 LT last Saturday and it already came with a leveling kit and mud grip 33's and the tires I have just about determined are about 60ish lbs each, and I was wondering if I go with the Atturo X/T 33x12.5x20 and replace the stock wheels (18's) with maybe some lighter XD's (if possible) and get a few more MPG's. Currently getting 11.7mpg

Thanks,

What would you suggest then?

I'd like to keep that agressive look. I'd really like KO2's but I can't seem to find a 33x12.5x20..Might still decide to go with them and settle with 33x12.5x18

Pass on those tires ASAP. Go with the KO2s. I had the trail Blades and they didn't last as long as I expected.

Yup. Atturo makes some junk tires. Many of theirs only last 10-20k miles. Any money saved by increase in mpg would be spent on tires. BFG KO2 is an excellent tire. Personally I have run Hankook Dynapro ATM on 5 trucks now and never gotten under 50,000 miles per set.

Or you could go with the Nitto trail graps. I got over 55 k on mine before I switched to Goodyear Duratracs, and actually got better gas mileage than with the duratracts which are a smaller, lighter tire. Still can't figure that one out.

11.7 mpg in a 1500?

you must have a 2500 with that gas mileage.

I had a '11 1500 on 33's and got 15mpg all day and i thought that was bad. 17mpg on highway tires
It's definitely a 1500. I am thinking that it is the tires for sure though. I have a friend that gets 15 with his 33's on 20's.

I don't have a lead foot so that isn't the problem..

What would be equivalent on the 33x12.5x18 on the KO2's? I don't know how to really read numbers on them.

you will rub with anything larger than a 33 with just a level. and it means they measured the actual height while mounted on a 10in wheel. the height would be different on a 8.5in stock wheel.
