DURATRAC TIRE HELP! Advice 315 70 17 for JKU 2.5 BB

I have posted some other threads recently, and have gotten Great Feeddback! This Forum is awesome.

From feedback on tires so far I am leaning toward getting 315 70 17 Duratrac Tires for a 2014 JKU.

I have bought a 2.5 Teraflex Budget Boost, want to 17 wheels on it and 5100 Bilstein Shocks.

Now just need to get tires!

Only thing is I have gone over and over threads and every tire has its good and bad qualities, and then size is an issue for $ that may have to be put into the jeep for future mods to compensate for tires.

So I wanted to ask, does anyone run 315 70 17 Duratrac Tires on JKU? If so whats your setup like?

Do I need to regear or with that tire am I good with the 3.73 gears? Do I need an air intake mod or programmer with the 2.5 Budget Boost w/ shocks? I just dont want to break the bank for future mods to accomodate the bigger tire for appearance of good tires but damn the bigger tires look awesome on the 4 door models.

I was steered toward the Duratracs, cause of great reviews, and the fact the tire is lighter and is not a true 35 at the 315 size, measuring 34.4 and w tire revs of 604 per mile....They are classified as D tire though.

I was weighing getting 33s before but honestly in my opinion they looked small on the 4 door models with a 2.5 lift. The MTZ were rated very high, but I thought the 33s looked/measured smaller w/ the lift in person. I looked at the BFG K2s and they were rated high with great reviews, and you can get them in a 34 basically, but only thing is I heard that they have a tendency to hydroplane in wet terrain.

All recommendations and input is much appreciated! Thanks for all feedback!

Get the 315's and call it a day. If you get the 33's you will regret it. No need to regear w/ 3.73.

Hillcrester Thanks,

Thats a great thread! A lot of good info..

I am really leaning towards the 315s

Would anyone know if I needed a programmer or air intake with them?

Depends if you have an auto or manual and if you care about your speedo being off 3-5 MPH.

Thanks, I have an automatic...Does the air intake help with the mpg, is it necessary?

I had heard the programmer will be good idea for the tire size but not necessarily a necessity..

For an automatic it helps with the shift points which will help with MPG's. It also helps with correcting your speedo which effects your odometer. You can also correct TPMS, set other things like day time running lights, blinkers, etc. They are good to have for an auto. For a 6 sp they are less useful.

Happy with my 315/70/17 DuraTracs on RR wheels. Hasn't affected my city MPG, but cost me a couple on the highway, compared to stock wheels and tires. I have a RC 2-1/2" lift and OME HD springs w/ 10mm spacers on front because of the additional weight of the bumper, bull bar and winch. I run the stock tire/wheel combination in the winter. I have an AEV Pro Cal to adjust the speedo and tire pressure when changing.

That setup looks amazing on yoru Rubicon. I think I am set on getting the 315 Duratracs. Only thing is I bought a TF Budget Boost, so I will using that to compensate for the bigger tires. Is your Rubicon automatic?

I think I will get the TF Budget Boost, Bilstein Shocks, Superchips Programmer and 315 Tires.

Thanks for the advice, do you have any recommendations for the type of Programmer to get?

The AEV ProCal is pretty popular.
