BF Goodrich KO2 - C2 vs E2 load rating, ride quality affected?

[NASSTY]

There was some discussion in another thread about these - I was really curious about them too, but they were significantly more expensive than the KO2. Would love to hear from someone running them, and especially about the height (if they actually measure out the same as the KO2). The tread was reported to be a bit narrower.

The load range C KO2's cost $17 more (each) than the Goodyears on TireRack.

Just wondering why? The beadlock / beauty rings are symmetrical so they shouldn't change the balance. Could be missing something here though as I haven't owned beadlocks prior to this.

Weight is weight regardless of symmetry. Discount balanced them without the rings and nuts and when I drove it, it was unbearable. Made a u-turn and they rebalanced them with the rings and nuts and they were about a 1/4 ounce off on every wheel from the previous balance.

I've had both KO2s C and the E load range. The Cs definitely road better and I will never use a E on the Raptor ever again. I get 60,000 out of both. If you run low tire pressure with the E they don't last long at all. BF Goodrich will tell you the same. So to get good mileage out if the E range you have to run around 50 psi for them to last and you notice a bounce on frost heaves and feel it in the steering. I run 40 psi on the C range and Noooo complaints

Correction on what I last said. I replaced mine aroud 50,000 some thousand miles but I could of gotten close to 60

On Gen 1s right? I noticed that the tires (going from a Gen 1 to 2) are not going to go that range on the newer Gen 2 Raptors. Different tires.

Yes Gen 1. The Gen 2 come stock with KO2 load range C also. Stick with the C range

Yep, I will have to replace them before 40k but yes I noticed the Gen 1s last a long time. Another thing the Gen 1 was better at, the exhaust sound and tires.

What tire pressure are you running? I maintain at 40psi. If any lower you end up getting less tread life

Thank you!

What nuts? Do you mean the trim ring bolts?


I’ve never seen 1/4oz make a 65lb tire unbearable.......
