JLU - Tire load rating

[CreekFreak]

My wife's JLU with 37" BFG K02s, Method wheels and Metal Cloak lift.

She is going to need new tires very soon. I'm just looking to go with K02s again due to price and availability.

So my question is, if I go from a 37x12.5xR17 D2 down to a C2 tire load rating what will I gain or lose?

She might hit a muddy trail once in a while while following me in my JTR. But 90% of the time this is just her daily.

The C rated is a slightly smaller tire because it's an OEM size for Raptors, I believe, and Ford wanted to eke out every last MPG. So consider that. I'd probably stick with the D. Either will be an excellent choice.

Cs have a less stiff sidewall than Ds. That means the C will ride more comfortably while being squishier when cornering.

Ideally she'd be able to wait for decent KO3s to come out.

K03 37x12.5R17 C won't ship till sometime next year. To second it the C will ride better than the D, a little quieter too. D and E rated tires are really for pickup trucks hauling heavy loads. A fully kitted out JLU is still below the 7500lbs to max out a C tire and warrant going to a D. However if you spend a lot of time on the trail and in the rocks the thicker sidewall of the D is definitely a benefit. Since its your wife's daily and occasional weekend warrior I would go with the C rated ones.

Thanks all! That's kinda what I thought with it being thicker. It's more muddy down south than rocky. I wanted to double check and make sure I wasn't going to be at a huge disadvantage doing a C rated tire. She runs over more screws than she does sidewall damage lol

KO2s are decent at pretty much everything...except mud. I have 37" KO2 Ds and really like them, but I don't do mud. At least I didn't before moving from CO to WA.

Mud terrain tires would likely be a better match, but they're usually fairly aggressive...loud.

I'll most likely replace my KO2s with Mickey Thompson BB ATs.

The Mickey BB AT has a lot of siping, which should make them work well in the wet PNW for you. I just don't have much time in wet pavement driving on mine to tell for sure.
