Thread: Tire E rating vs C rating

  1. #1

    Default Tire E rating vs C rating

    Whats the exact difference between an E and or C rating tire? What would be fine for a WK? Thanks. I can get a great deal on GF's but they are c rated, not e rated. Thanks.

    E rated means its 10 ply vs. c rated which is 6 ply, in my tires at least. You would want e rated for a heavy truck or something like that. C rated is going to be alot more smooth ride and not be as rough.

    I am running E-rated tires with no regrets. I actually like the firmer ride.

    I happy your happy with them. My point is also, is it really needed? A Hummer H2 runs d rated bfgs from factory, so a WK doesnt seem any bigger or heavier that that. Just curios if E rated is really needed?

    Not necessarily needed, but is it bad to have a sturdier or stronger tire? Besides the the E-rated tires were less expensive than the c-rated ones in my case.

    Yeah...my Duratracs were cheaper and more available in an e. I do mostly city driving and find the ride quite comfortable...and I also like the added piece of mind of the extra layers.

    I dont want this to happen again :

    An E rated tire is built to handle the work and the weight that a 1/2 to 1 ton truck will put them through. They should last forever on a WK but might ride a bit rougher. Unfortunately most of the sizes both stock and lifted for WKs are E rated but it would not stop me from buying the tires i want. Its not NEEDED its just whats available in most sizes wk owners want. If you want stock size BFG AT KO the closest you can get is a 245/70/17E.

    You have to look at the manufacturer web site for the tires. Alot of companies will offer standard load and E range tires so you can choose what you want.

    I dont think the ply of the tires has anything to do with your pic, i think thats an issue with that tire specifically or a defect.

    Most general tires that will fit the WK w/o a lift are NOT E rated tires. You still should not have any issues especially with a good name like General tires. I plan to get Grabber AT2 or BFG AT in the fall.

    Is this for your gf's WK? Just get the C, its cheaper, and it rides better (I would be assuming she wants something more cushiony than a stiff ride we might prefer), and she won't care or know the difference.

    You don't need E rated tires. FWIW, that's what we have on the CTD Ram.

    Rather surprised you've found they are cheaper than the C rated tires, I've found the opposite to be true in my search for CTD tires.

    I actually have a question as well.

    Where do XL tires fit in? Are they simply like a C+, and the SL tires are C?

    Ok, so if I have the choice of a E rated (10 ply) and C rated (4 and/or 6 ply) I should go with the C rated because its smoother (and lighter).

    Tell me if its true : For a specific model/size, a "C" rated (or lower rated) tire will have a much more rounded sidewall at the bottom (where the tire is in contact with the ground) than a "E" rated tire. Or there is not much difference ?

    Nice. I have pics of your jeep. I bet those Load E BFGs will last for freaking ever too! The E is usually a compound made to with stand the weight of a 3/4 to 1 ton truck so they are made to wear longer. I cant wait to get a set. Its been years since ive had BFG ATs and i really miss them.

    Where did you get them? Ive only been able to find them in the $200 each price range and i want 5.

    I put E rated Duratracs on my Wrangler - No issues except I think the tires are a bit heavier. Tire dealer said E's were easier to get.

    Discount Tire. That price sounds about right, I only got 4, I left my old Firestone Destination MT as the spare.

    I had E-load BFG AT KOs, ran them for a few winters then gave them to my fiancée who is currently running them on her XJ. They still look brand new (tread wise) lol

    I had a set of BFG KO's (E) on my WJ and got 120,000kms on them. Now with my new WK I put the 265/70R17 load range E's on it again.

    I find it quite rough, I would have gone with C's if I had to do it again as it is my daily driver. it didn't seem this rough on my WJ.

    Our roads suck around here as well which doesn't help.

    Tire shop accidentally gave me a set of E-load BFG All-Terrain 265/70/17's instead of the C-load. There's a $20 per tire difference, so I'm keeping them. What pressure should I be running? Kinda freaky looking at my EVIC and seeing 50 psi, even though the max tire pressure is 80.
