I’ll do anything to improve my fuel economy even by just 1mpg, but love the look of the BFG KO2’s. I have Nitto Terra Grapplers on now and while they look sick, I’m considering a Gas mileage tire since I never off road and only drive to and from work.

Your best bet for “fuel saver” would probably be a street radial for SUV/truck. The fuel economy will increase with stock size radial tires that are light unlike all terrain or mud tires. This would work great especially if you never off-road. If you ever drive in snow and don’t want two sets of tires you need to be careful that your radials can handle it.

An example for street radials with white raised letters would be this Yokohama Geolandar H/T. This tire weighs around 1lb-5lb less than the terra grapplers and has a highway tread that will pay large dividends for rolling resistance and fuel economy.

On another note I began using Lucas Oils injector cleaner in my daily driver to see if it actually works. While I have only gotten through one full tank I was still able to see a 1.0mpg-1.5mpg increase in my fuel economy. I have not done the math to see if this product is cost effective like it did improve economy.

I am no expert but this is what I can say from my experience of going from stock to oversize mud tires. Do your research on tires and make sure it is absolutely the tire you want on your vehicle for the next few years to come.

Thanks for the insight! I appreciate it!

Terra Grapplers are pretty tame. Unless those are worn out, you will never make up the money in gas mileage. I do understand filling up just a little less is a benefit in itself.

That said, you need normal P rated tires or maybe C rated. Keep it as light as possible. It isnt all about the tread design.

If your Nittos are dead, then Michelin LTX tires are pretty solid choice. Stock size they are just 39lbs.

The Nittos are only 41 lbs (stock size - standard load), so you could go spend $1200 on tires and not notice a damned thing.....this is the likely case.


So...do you have a roof rack? Remove it. Rock rails, skid plates, ect? Remove that weight. All the tune-up items taken care of? Filters - plugs - FLUIDS, grease driveline, ect.... No lift right? That absolutely murders mileage.

Another option if you have cash burning holes in your pockets...rims. Stock rims are mostly around 30 lbs each...you can find some in the high-teens/ low twenties. That weight savings should help a good bit.

With respect, I don't understand the logic behind dropping $800 on a set of tires to save $2 per tank of gas. Spend a dollar to save a dime comes to mind. Just enjoy the FJ.
