I am back. I had a 05 Rocky Mountain Edition TJ and traded it in 9 months later for a 350Z. After 4 years I sold the 350Z and just bought a 2010 2 door Sport auto. When I had the TJ I put 33 inch Thornbirds on it and it looked incredible but the gas mileage went from 18 to 12 MPG. It also had no power. Trying to avoid that this time.
I am looking to go with an aggressive looking 33 by 11.5 inch radial tire. I will put on a 2 inch BB if it looks like it needs it with the 33's.
My question is strictly about gas mileage and power. What would be a good aggressive looking tire that is lightweight and will not sap a lot of power or gas mileage? A hard compound is good to as it will be used mainly on the beach with some light wheeling. It is my daily driver and I have a long commute.
Also would having 18 inch wheels weigh less overall than 15 inch wheels as there is less tire? What type of wheels weigh the least steel or aluminum?
It is good to be back in a wrangler. Thanks for the help.
JK's don't need to be lifted to run 33's, but no matter what you do wheel/tire wise, putting more rolling mass on the Jeep will affect the mpgs. If you update your speedo to the corrected size you will get a more accurate reading. Unless you swapped speedo gears in your TJ your odo was off, thus giving you erroneous #'s for calculations.
Alloys are lighter than steel, and each wheel/tire is going to vary quite a bit in how much they weigh. If you are that worried about it, you should spend some time on the tire sites like 1010 tires, and tire rack and find out what each weighs to help you narrow down your choices.
I did correct the speedo on the TJ and verified it with GPS. It was a legit 12 MPH. The Thornbirds are almost 100 pounds each. Cool if it is a second vehicle. Thanks for the tip. I did not know tire rack listed the weight of the wheels.
"I'd look at a "highway" tire, like a mild A/T or A/S, like a Michelin LTX or similar"
Thanks but looking for an aggressive tire just not quite as aggressive as the Thornbirds.
I a looking at MTR, Nitto Trail Grappler etc.
Troy, The Nitto Trail Grappler is very aggressive looking tire that is very quite running down the hiway.While your looking,check out some Good Year Dura Tracs. Just watch the size and weight of the tire you buy. With auto/3.73 I'd not go over 32".........
My set up is a 2" bb with 285/75R16 Cooper Discoverer S/T, pretty aggresive for an all terrain, on 16 x 8 Procomp alloys. Most of my commute is 45-55 mph and I usually average 17.5 - 18 mpg with the 6-speed and 4.10 gears, I have no complaints about power. They handle nice on the street and handle the trail pretty well also. I have 35k+ on the tires and should be able to get another 15k-20k miles out of them.
