Tire load ratings and construction

    I am about to buy a new set of tires for my Yukon XL 3/4T. Factory specs indicate a load range E tire (LT245/75R16). My understanding is that the load range E is a 10 ply and rated about 3,050 lbs at 80 psi.

    Besides plowing I also haul a heavy travel trailer at times (about 8,000 lbs) and have the heavy duty tow package.

    As I look at different tires and consider going to a little wider design (LT265) I see that many tires are rated as a load range D tire but can still carry 3,000 lbs at 65psi. I assume these are an 8 ply tire.

    My question - is the D rating at 3,000 lbs sufficient or should I stay with a tire that is E rated due to construction and psi rating?

    I was considering the BF Goodrich All-terrain A/T but they don't have the E rating in the LT265/75R16. Bridgestone Dueler A/T does have the E and I am leaning that way.

    Regarding your question, I had the same situation on our 2003 Dodge Ram/Cummins, and I went ahead with the 3000 lb 8 ply tire and had no problems.
    This ply rating is an old cotton count rating they used years back which is not 100% accurate anymore.

    On the sidewall of the tire, it will state the acutal ratings.
    Example: LT 245 75 16E Cooper M+S
    Tread: 2 ply poly + 2 Ply Steel
    Sidewall: 2 ply poly

    This means that this is a 4 ply tread tire with a 2 ply sidewall, even though, it is a 10 ply rated (E) tire.

    Some of the heavier duty tires will have a Tead: 2 ply poly + 2 ply Steel + 2 ply Nylon. Now this would be a 6 ply tread tire. I know that Goodyear makes these and call them severe service tires which are uses by folks who drive county gravel roads daily out here.

    Hope this helps you out.

    I made the decsion to go ahead and get the standard 245/75R16 E Bridgestone Duuler A/T Revo tires. The narrower tire will probably do better in snow any way and I won't have to worry about the load rating.
