Duratrac LT315/70R17 or LT35X12.5R17

Are these basically the same?

I'm looking to toss these on my 2012 JKU.

Well, doing the math

315/25.4=12.40" section width
12.4 x .70=8.68" sidewall height
(8.68x2) + 17" rim = 34.4"

So, yeah, it's close. It's probably the same tire. I used a calculator, so I carried all the trailing decimal places.

Load rating is probably different. 35 LT will probably be E rated. The 315's will probably be D.

I would say they are comparable, but not the same tire. As mentioned, the 35's tend to be E rated for load, where as the 315/70's can be C, D, or E, rated.
Sometimes the two are near the same price, other times the metric sized tire can be considerably less $$$. Rarely is the inch tire the cheaper option. Perhaps there is a premium on the image of "35's".

According to GY, the load ratings are the same, though the info on their site is sketchy for the 35, and tiresize.com doesn't list it, at all.

The 315 DR is .4" shorter than other GY MTs in 35 (e.g. MTR), and I'd think that would be true of the DT, as well.

Typically, the dimensions of a 35 is slightly taller than a 315 and a 315 is slightly wider than a 35.

They pulled those sizes for comparison in the KO2's and got a couple photo's here: https://www.wranglerforum.com/f27/315...2-1616601.html

In the KO2, you can actually get the 315 in a C rated tire which is a great match to our weight with JK.

I just purchased a set of LT315/70/17's and they are E rated. Standing them next to the 35x12.5x17 TOYO Open Country MT that I took off it is very difficult to see any difference. According to TOYO website they are 35 x 10.5 in measurement. They are several dollars cheaper than the 35". I switched over to the 315 to see if they drive better than the 35. I found that the wider tires tend to try to run up the sides if the "ruts" in the asphalt that is the result of 18 wheelers driving on the heat softened pavement in the south. I haven't mounted them yet, tire dealer wouldn't mess with deadlock rims so I have to do it when I get time... lots of time. I took me most of a day to get the ring off the spare without stripping screws off in the rim.

35's/315's are pretty much the same thing, if anything 35's are just a tiny bit taller, and the 315's are slightly wider, but you should not notice the difference unless you have them side by side, i haven't have any side effects as a result of the tires being a bit wider, for example I went from 315 KO2's to 315 Nitto Trail Grapplers a few months ago, the Nittos are perhaps 1/4" taller which is nothing, but 3/4" wider than the KO2's, and my Jeep drives the same as before, i do feel the weight difference for sure though, and even more than that, the MPG loss, (2mpg less). No issues with the Jeep tracking the road crowns with 315's, and i still do 80-90mph with one hand without sweating, for instance, at 31psi:

I'm running a good amount of caster, 5.3-5.4* (also running an Adams 1310 front DS, i don't know if you can run this much caster on the stock DS, but i haven't have any issues so far in 2 years running it this way), and also my toe settings are bit on the max side, 0.16-0.17*, no issues so far with tires wearing down in a weird way, i have almost 5k on them, so it's time to rotate, and i'll keep my eyes on them like a hawk, if i start seeing toe abnormal wear, i'll have it realigned, but so far so good, this toe settings is something new i'm trying since i've the front lifted 1" a few months ago

Here is my alignment sheet, lifted 3" in the front, 2" in the back

Hope it helps.

I don't think the Duratrac even comes in a 35x12.5x17?
