Estimate on MPG after 2.5" Lift and 33"s?

Hey all,

Just wanted to get some insight from others. Getting a 2.5" spacer kit and 34" (really, a high 33") Nitto Terra Grappler ATs on my 2011 Sport.

Any experience with how much I can gas mileage drop I can expect? I believe it's at about 18 city and 21 highway right now.

Also, will I require any regearing on a 2011 Sport S?

Any insight would be appreciated!

-R

I have an 08 Rubi with a 2.5 budget lift and 33's. I get 15mpg pretty consistently.

If you have the auto with 3.73, you'll be running at around 2K RPM at 70 (1834ish) a little lower at the standard 3.21.

You can just fill out the charts here and see. (I ain't good with maths)
Gear Ratio Calculator

If you drive around town quite a bit, your city MPG may suffer. Same if you're running a wider tire. (That's probably the biggest drain going from a pizza cutter 32 to a 12.5 -33")

Need? No.

Want? Probably. Depends on whether you have an auto transmission (will probably badly want a regear) or a manual transmission (will probably just want a regear).

My stock 13 KJU with auto & 3:73 gears was getting 18ish before. After TF leveling kit, 17x9 DCIIs & 33" Cooper STTs I'm now getting between 15-16. I figure the extra width contact patch on the road, the extra weight of the tires and the extra air resistance fom the lift is the cause. You can expect some loss in MPG but its worth it.
