i seriously dont think nitrogen in tires is an improvement. from what i know its only useful for temp changes. it does not fluctuate as much as air. also the air is mostly nitrogen anyways. also it leaks out slower than air, but thats it. not worth paying $20 a tire to fill it. but then again, i could be wrong..........

Agreed, might as well check it every week or two and fill as required.

Well, if you stay in 2 wheel drive, you could cough up the coins for a gearvendors OD to slow RPM down some, might help some but it could get really ugly if you forget and slap her in 4 wheel drive....

Put a fart can on the exhaust... easily an extra 2 mpg gained. Then you can join the street racing scene ha
