I'm not aware of an "E" rated 315 BFG. The KO's are a sturdy,quiet,well built tire. BFG just can't seem to make them round. The majority of them seem to take 7-10 oz. of weight to balance. I may just end up with them someday when the camper goes.

 

I am happy with my M/T 315's with my camper and hauling my jeep. I run 50psi and don't notice any wandering or other ill effects.

 

If they are required to sell a tire that is no lower then whats on the truck from the factory for said truck, then how can they sell a D rated tire when Dodge has it listed on my door sticker 265/17-E as the tire required for the truck?

 

The E rated stock tire has the same weight rating as the D rated in the BFG's. It is about weight rating, the letter rating is just a reference. Interesting that your truck lists the tire size specifically, my 2006 door sticker has both the tire size and the weight rating listed, signifies one, the other, or both are acceptable.

Also, the door sticker is a reference of what was on the truck when it rolled out of manufacturing. There is actually, or should be, the weight reference somewhere, that is all the DOT looks at - weight capabilities.

 

Ditto with everyting above. I have been running the KM2's since Sep and tow a 10,000 5er. Less bubble on the sidewall than the stock E rated when I tow. Like they said above, they are the same max weight load as the E rated tires that came stock with the truck.

FYI - got mine at Costco for a good price. They seem to run the $60 off any set BFGs, which include the mudd and all-terrain almost every quarter.

 

That was a typo, I meant to type "D" but I guess i was thinking about E's..

 

I have no idea, I guess it depends on the tire, but what I look for is for one tire that's appreciably different than the others, you can tell right away the "hot" one needs air. (Given a balanced load) Same thing with wheel bearings- I just get a baseline and take note if they get hotter.

 

I run "D" rated tires on my truck and have had no problems. Granted, I do not tow much at all. I have read on this forum that a "D" rated tire will give you a softer ride. I have 33x12.50x17 Pro Comp MT and have about 30k miles on them. I probably have about 10-15k miles left on them if I had to guess.

 

The only weight ratings showed on my door sticker is the max axle weight with 265/70/17-E tires. The other 2 stickers show tires size and air pressure based on passengers and there luggage. How many plies does your D tire have 6 ply? I'm all most sure its less then what E tires have. Anyway you can run any tire you like but I feel my life and that of my family's is worth more then the few dollars I could save by buying D tires.

JMHO

 

All tires these days are a ply rating.. radial tires don't have the same number of plys a bias tire does... so E's are a 10 ply rating, but may have only 2 plies...

 

Yep. I've bought tires before and the salesman (a tire GUY) sez "They're a 10-ply tire." Read the sidewall, dummy. I can.

 

I ran the BFG 315 AT/ko tire on my 05 and never had any problems towing 6k.
I ran Mickey Thompson tires in the same size with the same D load range for about 6k miles, and took them off. Even though they had a similar weight rating, the sidewall flex was apparent in these. Hiway speeds and towing tag of 6k and 28' long, when I would pass a semi and catch the turbulence the little movement in the trailer would start a reaction and before I knew it I would be white knuckle trying to keep the truck in a straight line.
My 07 has stock equipment, as that works the best

 

I have BFG A.T. 285-70-17's on my 06 with 30k on them and regulary tow 21k-23k trailer(every weekend). I keep them at max psi and rotated often, no problems so far.

 

I went from a bfg a/t d rateing to a dick cepek e rateing and that cured my Death Wobble...Finaly

 

I've run D rated BFG tires on mine for over 100,000 miles.

BUT, just because it is rated to carry the same as an E tire doesn't mean it is as good. The sidewall on some tires are so weak it feels like you could stick your thumb throught them and I've seen videos of D tires on the dyno with the sidewall wrinkling under the torque. I also had a BFG blowout on the highway that had a cut in the rubber on the sidewall. No plies were affected, just rubber, and it blew.

I finally switched to Toyos and what a difference from BFG! The 285/75 is one stiff tire. Also interesting is the difference between the Toyo 285/70 and the 285/75. The 75s are WAY stiffer and both are E rated.

I've decided that a real truck needs a real tire. The main reason for running the D rated ones was that they were available and E was not. That's not a good enough reason anymore, regardless of how many pounds it can carry. I got my 315s with a set of H2 wheels and loved their performance off road.
