Tires and MPG

Just bought a 2000 Wrangler Sport and was hoping to get some input on what would be the best tires for road performance/gas milage. I won't have this jeep off road for now and it is my daily driver. Any ideas? Thanks!

I had 31's and was lucky to get 16 mpg during the summer and 13 in the winter-
When I needed to replace them I had a set of 215's around and now I can get 20 mpg...

That said it's a 4 banger auto and I drive more by the tachometer than by speed (slow and steady saves the wallet). Depending on your setup and driving style these numbers will change.

I liked the look of the 31's but I couldn't afford to replace them and the gas money is nice to have

your best bet would be some A/T tires. i would say 30x9.5x15s or 235/75r15s. These are stock or close to stock size. The bigger the tire the heavier it is means more gas. BF Goodrich All-Terrain T/A KO BFGoodrich All-Terrain T/A KO
Or Goodyear Wrangler Silent Armors are good. Goodyear Wrangler SilentArmor
I have had both and either one is very good. I would say the BF Goodrich are the most popular though.
I have the goodyears on mine and they are very good on highway and light trail riding. Also very good in Snow.

215/75R15s i believe are stock size for Jeep Wrangler SEs. These tires are small but would give the best gas milage.

Thanks!

I should have added that its a 6 cylinder. I'll check into the tires you recommended. I'd love to trail ride but the reality right now is getting to work with the best milage possible.

I'd stick with a good narrow well-siped 30" snow tire aired up to 33 psi (to minimize the footprint), all terrains are not the best choice the conditions you'll be facing this winter. All terrains have a bigger footprint which makes them more prone to sliding and spinning on icy roads.

Tire weight and wheel weight, are in the mix I'm sure. Pick up some light centerline wheels if you can find them on sale.

I have a 99 Sahara 4.0L with 30" BF Goodrich All-Terrain T/A KO's. I've put 30,000 miles on them and they still have excellent tread. I don't do much off-roading but I do drive 30 miles one way through Minnesota and Wisconsin winters. Excellent tire in the snow and I still get 18-19 MPG in 2wd (obviously a little less in heavy snow and 4wd). Also, they don't roar on the highway like some AT tires.

I have a 2000 Sahara with 33" X 10.50 bfg all terrains and get around 12-13mpg on the interstate. Depends on traffic and wind. Jeeps are like refridgerator boxes in the aerodynamics dept. I feel confident in saying I get around 15-16mpg on the highway runnin 55-60. I wish I had a 6 speed!
