New tires

[nikhsub1]

So what is the B, C, D ratings mean? Hardness of the rubber? Speed rating?

Sidewall stiffness/plys

Always have a budget in mind, and with tires, think big! I've been a Toyo boy forever. Yes the MTs are a heavy tire, but the RTs are similar to stock weight, and Toyos wear like iron providing you rotate them. Figure somewhere in the neighborhood of $1400 or so.

I have had my RTs for almost 30,000 and seen to still have half tread. Road noise is not bad and ride fairly smooth. Only complaint is a bit slick on wet roads however it’s a truck.

Tire rack has the stock c rated tires for about $1100View attachment 146043

Thank you

I just switched to e rated tires and can’t feel any difference. I would expect about $1200 out the door at America’s tires. By the way 4th set 41,000 miles all c rated until now, hopefully I can get a little more out of the e tires.

You only last 10k per set? I’m at 11k and my tires look new.

Like I tell my wife Smiles per gallon. The mountain roads eat them up. My quickest set of tires was on a new f250 with BFG long trails, 7000 miles but she was a big ol girl.

The load range C, D, E used to indicate the number of plies used to construct the tire and gauge it’s capacity. Since tires are now using less but stronger plies the system is now just a listing of the capacity rating and max air pressure. The load index number is an actual number in pounds that the tire can hold at the max weight. The load index 113 on the stock BFG’s is 2535 pounds, most E rated tires are 121-125 so 3197-3638 pounds. Generally the higher the load range or load index the harder the rubber, thicker the sidewall, and heavier the tire. I prefer to stay on the lower side of what’s available for the actual weight of the truck, but there aren’t many tires in the stock C load range in 315/70R17. Discount tire only shows a Toyo Open Country M/T, Toyo Open Country A/T III, and the BFG AT KO2 in C load. They show 11 tires in D and 24 tires in E. In the 35x12.5R17 there is only the Goodyear MT/R available in C, but 3 in D and 29 in E. Looks like my tire choices are very limited. Since I’ll be doing 20K miles per year on the Raptor using it as a daily driver I’ll stick with the stock size.

The problem is Brodozer F-250’s, when everyone first started lifting them the tire companies realized the need for heavier duty AT and MT tires, so kind of all the sudden all of the larger sized are only available in E or maybe D rated. Rather than making both a C and an E, most companies standardized on the heavier E rated tires. I see many with Jeeps running E rated tires for the 35”+ sizes, so hard and heavy tires capable of supporting 12,000+ pounds of diesel truck on a 4,500 pound Jeep. I can’t imagine that a C load rated tire wouldn’t be better on the trails, with more flexible tread and sidewalls to grab obstacles better. People drive them and don’t complain about the ride, but on my 2005 Nissan Titan going from a stock tire to an E rated BFG KO made it ride terribly. On my Bronco the D rated tires wore better but sucked in the rocks as they were too hard. I went back to a C rated MT/R and was much happier.

It looks like yours were over inflated to wear out the centers like that, or they weren’t rotated.

This is Raptor 101; the C rated KO2 is Raptor specific tire or it was in ‘17, an iteration of the same rubber with more compliance in mind.

These Toyo A/T III have a 50K mileage warranty. I haven’t searched to see if anyone here is using them and if they work well on the Raptor.

Wow someone's got me beat. 28,000 miles on my truck and my second set of BFG's are already bald.
