Both E rated, side by side pics.
I was at DT this morning doing the upgrade from 285/70/17 KO2, i wasn't aware of a side by side comparison between both versions, so i asked my local DT store to put them together for a couple of pics.

I went with the 315/70/17 given it's a couple of bucks cheaper, and a little lighter too.

The one in the left(shoe in pic), is the 35x12.50x17, the one in the right is the 315/70/17, they're both KO2
315/70/17 weights 62 lbs, 35x12.5x17 weights 66lbs, other than that, they're pretty much the same height and width unmounted, at least to the naked eye.

Width, not the best angle, but the 315 is just a smidge wider, though you can't see the diffence because the camera angle, difference 1/8" or less if any

Height, the 35x12.5 is perhaps 1/8" taller

Can you measure the actual height when you have them on your jeep

Yep I did that yesterday soon after they were on. 33.5" mounted on 17x9 wheels.

Glad someone noticed the "Lack" of difference between 35 and 315. Knowing this, getting 315's is a no-brainer now when I get an upgrade this summer.

Im just worried about Discount Tire saying that they "Cant" install a 315 on the stock rubicon wheels. :mooning:

I had inquired of BFG re the differences a while back. Per BFG: First, the 315 has a slightly different angle on the mounting edge to allow for a narrower rim. Second the 315 has 4 lbs less rubber in the perimeter. Third the 315 can be used in dual tire applications, such as a dually truck.

I am so glad I came across this thread. I will be choosing the 315's on Stock rubi wheels.
