Stock (for my 99) was a 225/75. So anything over that will result in incorrect info on odometer. A 225/75 is a 28x9..

Your at a 14.5 percent increase in tire diameter and your speedometer reads like 17 percent too slow... So 50 turns into 60 mph! The one thing I'm not totally sure of is does that 14.5 percent increase in size throw off your mpg by same percentage. If so you'd go from 20 mpg to about 17, which sounds more accurate... But like I said, idk if thats the correct math..

Haha 35's on 3.55's.. Careful
Anyways, at 35" you are at 19.25 percent over stock and your speedo runs about 24 percent slow. So when speedo says 50 your at 38 mph... And when speedo says 65 your at 50...
I'd guess and say your at about 13 mpg...

Fuel economy also really depends on where you live. If you live near flat roads with 45mph speed limits you are going to get better fuel economy than someone that lives near huge hills with 35mph speed limits.

I get about 11 mpg all city driving, which is about 180 miles before the gas light comes on, and it's KILLING ME! I've changed the plugs, the air filter, cat-back exahust, and upstream O2 sensors. I'm going to flush the whole cooling system this weekend because it's disgusting, but I don't expect it to increase my MPGs.

My xj is bone stock. Anything else I should look at to bump the MPGs? Tires are always at the proper rating so that's not it either. Pretty stumped here.

fuel injector? maybe try running some BG44k or Techron or seafoam.... might have buildup of gunk...
