I was looking at a RoverTym 3-4" lift and possibly throwing on some 33's. I am wondering what kind of mileage you guys have experienced after the big lifts and new tires.

 

with taller tires your fuel econmy should increse a lil. Taller tires would make a higher gear ratio thus saving fuel. 33" tires on a disco would be a lot of differance, it will feel as if it don't have much power than it did. also if you are running 16 wheels you won't find 33" tire by that size, if you want 33" tire in a 16" wheel you will need somewhere around a 285/75-16. hope this helps.

 

Thanks Mike, it does help.

 

bigger tires will decrease your mpg around town since your engine has to work harder to turn bigger tires.. but your mpg on the highway will increase since bigger tires make less revolutions thus dropping your rpm's. with 33's it should about even out...
