Gas Mileage 37's vs. 35's
 

Can anyone with experience tell me what to expect "mileage wise" going from stock AT's (basically 35s) to 37 Mud Tires same width?

Thanks in advance

Hard to compare them as the engine control system software for the later 37's squeezes more MPG's out of the bigger bore via the variable valve timing and updated fuel maps.

My 2008 3.7 gets 14 around town and up to 21 on the highway.

Running all stock and 38 lbs. in the tires. Regular gas.

Monitored by the Scan Guage I installed.

I have 37 mudders which came with my 03 H2 used and im getting 10.0 mpg No mods. Havent run it with ATs yet. I do have a Jeep which I went from 35 AT's to 38 MT's. Went from 15mpg to 12 mpg. Of course not scientific by any means but hope this helps.
