That is interesting that they are under 65lbs. It is really ridiculous how Ford is making 35s available from the factory in any Bronco model, the Raptor and the Super Duty Tremor, with 37s coming on the Raptor37 and likely the Bronco Warthog, yet, Jeep tops of at 33s.The optional 37's for the Raptor are 37x12.50R17 load range C. The tires are already in production, in stock and should be available for order next week. My local Discount has my order standing by and will process it next week. These new KO2 37's weigh just 64.8 pounds!
With tires like the KO2 now available with light weight, low noise and 3MSP winter rating, it should be a no brainer to offer 35 AND 37 on the Rubicons. I put 37KO2s on my JLUR no lift for a few days and had no rub and little change in performance. With a lift anything less than a KO2 37 looks silly on a JLUR.
P.S. I'm no KO2 fan boy - I actually don't like it off-road, and bought them simply because they were the only light tires that I could get in 37s after waiting for a few weeks on DC Extreme Country.
The fact that the even the 392 had 33" tires top is silly.
