So the Grand Cherokee eats gas but its soo much fun to wheel.
I have a 86 4 cylinder 5 speed 4.10s going to try to get the best gas mileage out this as i can.... Any ideas thinking 205s and lowering it maybe...

Nothing wrong with that. Give it a go.

I had a 2.5 5-speed MJ. Got ~26 mpg. Had no power though so it had to go.

My 2.5td xj had 195 tyres (tires) when I bought it with standard 3.73 gearing, pretty nippy acceleration.
Way too low though.

Soo i have some 31s i can get for my new daily would those affect my mileage to bad with the 31s and 4.10s

everything bigger is going to affect your mileage.

just depends on what your definition of bad is

Well my grand gets 17 on the highway i want to pull atleast 22-25

rackem

if you want 22-25 mpg...

dont put 33s on it.

i dont think it will ever happen with that.

Well.... no really... :P I thought 35s might get to the 30s

My 87 average 21 mpg stock on 235/75-15's. With the 2.5, AX-5, NP231. The only time I checked the mileage so far with the 33's it was getting 18 mpg, still with the stock 4.10 gears. It needs 4.88-5.13's with the 33's imo.

Driving habits help like when you see a red light coming up down the road,Don't be in a hurry to get up to it and stop just slow down and coast up to it.Taking off from a stop be easy with the gas pedal act like you have a egg under it.

But it's just too much fun beating the snot out of the pedals.the look on people's faces. Priceless...
Especially ones on their phones not paying attention.
