Yep, I realize that. You are spot on with the weight carrying, too. The C rated KO2 easily exceeds the GVWR of the JLUR.It's not the added physical weight of the E tire that makes the ride harsher than with the C, it's the overall stiffer structure of the tire that doesn't offer enough give when rolling over imperfections. The E rated tire is meant for a vehicle that's capable of carrying more weight than our wranglers.
Only having experience with the C rated 285 and now 315 ko2's, I too have been hesitant to stray from the C's. That was one of my reasons for not jumping up to the 37x12.5 ko2, which has a D rating. I'll admit, I'm still curious whether the D will feel noticeably stiffer, or will the added diameter, from the 37 over the 315, offset that? I may have to take the plunge to find that answer.Yep, I realize that. You are spot on with the weight carrying, too. The C rated KO2 easily exceeds the GVWR of the JLUR.
I just mentioned the weight in light of a conversation I had with a BFG rep when I was shopping for my tires. He said the difference was mre in the way it was constructed (specifically, he said people think of plies but that's not the difference). He pointed out that the weight of the tires wasn't that different because with other tires usually an E rated version would be much heavier and ride much worse than the C. He said the E in the KO2 rides very similarly. I haven't driven it, so I can't speak to that. The BFG rep claimed there was no significant difference in sidewall puncture resistance, either. I wanted the ride/handling to be as close to the stock 285 KO2's (C rated) as possible, as well as the slightly lighter weight. I've found the sidewall puncture resistance to be quite good, so far.
Yeah, was waiting for someone to throw this out there. It's an important consideration for sure. I've got the Ridge Grapplers and love how they ride. I don't notice much road noise at all, no more than the stock Rubicon tires. I'm running 26-28 I believe. In the summer I was heading up to the cottage pretty much every weekend with the top down and it rode great (84 miles/135km mix of highway and rural).Shouldn't one take the tire pressure into account for smooth ride not just tires along?
I run 37s KO2 D rated on stock rims and they are fantastic. Silky smooth at 85 mph and pretty unstoppable when aired down. Barely lose any ride height at 14 psi.Only having experience with the C rated 285 and now 315 ko2's, I too have been hesitant to stray from the C's.

So, the D rated 37 ko2's aren't that much rougher of a ride than the stock C rated 285 ko2's? Thanks for the valued input!I run 37s KO2 D rated on stock rims and they are fantastic. Silky smooth at 85 mph and pretty unstoppable when aired down. Barely lose any ride height at 14 psi.
I have to run 28-30 psi cause any more and my stock rims aren't wide enough, i lose contact patch, and the handling gets squirrelly
Rides much nicer than original 33s. Big part of it probably because bumps are smaller in comparison to the 37sSo, the D rated 37 ko2's aren't that much rougher of a ride than the stock C rated 285 ko2's? Thanks for the valued input!
Sweet, that's great to hear! Thanks again for the reassurance!Rides much nicer than original 33s. Big part of it probably because bumps are smaller in comparison to the 37s
Do you have any lift on your JLUR? Was wondering if you hit the fenders with the KO2 315's.I have the 315/70/17 KO2s and they've taken me everywhere I want to go and really are great on road. Their weakness is in thick mud and deep snow.
These are the C rated ones, I have a feeling that the 35" E rated ones might be a little bit of a harsher ride.
Keep in mind that the Bridgestones tend to run a little small, mine should be 34.4" but when I measured them at 34 PSI they measured in just a hair below 34"
