I tried in vain to search for this as I have to believe its been discussed before but I could not come up with anything. So, I am looking to get a 2014 Rub X Unlimited and putting a 2.5 to 3.5" (TBD) lift kit on it with some sort of 35" tire. Most of the tires I am considering KM2, TOC, DT MTR (please don't debate here) come in both metric and standard sizes. Dimensionally, price,etc. they are basically the same. What would be the be the benefit one way of the other?
When I was looking I rarely saw the same tire come in both 315/70R17 and 35x12.50R17 at the same time. I saw that one tire would come measured one way and a completely different tire measured the other way.
It really doesn't matter what system they use to describe the approximate size of the tire. The two sizes are basically the same, but vary slightly from one tire model to another. As long as it's the size you want you should focus on everything else about the tire that matters to you.
^^^ Yes, type of tire, Brand, and style, based on your Wrangler usage factor, is the most important. In other words, are you going to use it mainly on the pavement, or off road rock crawl, mudding, in the sand, back in the woods, and or a combination of all of that. So it's based on not only what you want, but more on what do you really need.............
Pmetric and metric sizes are exactly the same, just different. LOL.
Keep in mind not all 35" tires are actually the same size. (or 305/70/17). Tire Rack have actual measurements (not on the vehicle though). A BFG KM2 is 34.8". A 35" MTR is 35". We're not talking much obviously. But my 305/70/17" KM2, basically a 34", was 33.5" on my Jeep. Great tire, not saying anything bad about it. Just FYI.

Most 35" tires barely break the 34" mark in actuall tire size. PitBull Rockers are one of the few.

If you find a tire that has both "315" and "35" measurements take a look at load range/speed rating I bet one of those is different like these kooks for example the 315 are D rated and the 35s are E rated.
2012 Crush JK Rubicon. Teraflex 2.5" coil w/fox shocks & 1" rear TF spacers. TF monster front and rear track bar. 315 75r16 duratracs on level 8 zx wheels. LOD armor lite mid w/engo 10000s. Lots of other goodies.
I'm aware of that, but not that much difference. Most of the variance is due to how it sits on any particular vehicle. A 12.5" unmounted tire should measure pretty close to 12.5". Otherwise call it a 13" wide tire.

The MTR's with kevlar are 315 70 17, load range D and the 35 x12.50 17 are load range C
Pretty close in size, the big difference I see is the load rating.
Any input between the D and C load range on these tires ??
LT (Light Truck-35x12.5-17) tires have always been the tires designed for Pickups, Jeeps (a Jeep is neither) and SUVs due to the higher loading capability and higher CG of these vehicles. The LT-metric (315/70-17) are metric equivalent that the industry created to satisfy manufacturers need for global standardization. The globe is metric. In the past only P-metric (Passenger) tires existed and this extended the solution across the board.
Some LT-metric still have passenger like bias (less plies lower, max air pressure, tougher beads) as requested the OEMs to improve ride quality. Sometimes they are identical but other times they are not. This varies by tire manufacturer and even by tire size because an OEM may use that tire size. Just compare all of the specs for the LT vs the comparable size LT-metric and pick the one that best fits your needs.
It's best to have choices.
