I ordered a set of nitto terra grappler at's and told the salesman I wanted load range "E" well I get my tires and there "D". I called them and they said that Nitto doesnt offer "E" in 315/17/16 and I should go with another company or a smaller tire. Well a smaller tire is out of the question, I am sticking with the 35s and nothing bigger. I now have 305/70/16 nittos load range "E" they are great tires just balled. I plan on towing a gooseneck loaded to 18K and maybe more but mostly less, around 10-14K. My question is will my "D" rated at 3100 lbs be OK or will I need to send them back and go for the "E" at 3400 lbs.
Thanks I see what he was saying now. What is the % of the load on the axle of whats on the trailer. I seen somewhere it said an average of 20%. I know that there is variables and all but is that an acurate average? If so 20k at 20% would be 4k on the axles which would be well under the 6800 mark
To answer you question NO. I put a set on my f-350. Tread wear was terrible. The tire store tried to talk me out of them but I wouldn't listen. They were wore out a 40,000 miles. I replaced them with BF Goodrich Rugged Trail TA. They now have close to 80,000 on them and look like they will last another 10 or 20,000. My next set I was planning on getting Goodyear Wrangler Silent Armor.
One of our company trucks had good years on them and they wore out in one year, about 20k miles. 40k sounds like good wear on a tire to me but I know that a set of BF goodrich would last alot longer. I am more worried about the load range than the life of the tire at this point. Thanks for the input though.

Your load range "D" tires are rated at 3,195 pounds weight capacity @50 PSI. That means if you pump them up to 50 PSI, you can have as much as 6,390 pounds on the rear axle without overloading the tires. If you have 6,390 on the rear tires, you'll also have around 5,000 pounds on the front tires. That's 11,390 GVW.
You don't say which pickup have, but I'll bet the GVWR is a lot less than 11,390 pounds. So those tires are probably all you'll ever need for your pickup unless you severely overload the pickup. However, if you have a 2005-up F-350 SRW, your GVWR could be as high as 11,500, so you'd need to be wary about overloading the pickup over the tire limits.
When towing heavy, the CAT scale is your friend. Get to know one. Don't get caught overloaded.
A gooseneck utility trailer properly load balanced to 18k gross trailer weight will have around 3,600 pounds hitch weight. If your ride is a CrewCab PSD 4x4, then it probably weighs over 8,000 pounds before you tie onto the trailer. 8,000 plus 3,600 hitch weight is 11,600 GVW, or slightly overloaded for a 2005-up F-350 SRW, or severely overloaded for a '99-'04 F-350 SRW. So in that case you may definitely be at or over the weight limit for those tires. Again, get to know a local CAT scale.

Its an 01 F250 long bed extra cab 4x4. I am in the works of fabing up a transfer tank that will hold apprx. 70 gals of fuel. I plan on fueling up before leaving out loaded so that will add to the weight of the bed. I dont know what diesel weighs a gal. but water is 8 lbs a gal I think. That would be 560 lbs extra in the bed. That would be all I would cary in the bed. So from what yall are saying I may need to send the D back and get the E. We dont have any CAT scales around here but I have seen them, Do they charge you to use them? Does anyone know where some are at in the middle ga area.

I really don't give a rat's a$$ about the D or E rating. The actual lbs/kg weight is what matters. My 9.00R16s are Ds and 3480# rated. All the 235/85R16Es are only 3042# and quite a flimsier sidewall. Quite frankly, I don't understand why the letter classification even exists.
Here in BC Canada, the commercial highway scale stations keep their scales on 24 hours even though they are only until 4-5pm. Have you checked if they do the same down south?

The M/T is 3860# rated. Need a 8-10" wide wheel. I think it might be difficult (and/or costly) to find a wheel rated for that. Stock Ford steels are 3045# rated, but many aftermarket wheels are rated for less

OK The terra grapplers are rated at 3197lbs, I called the store I got them at and I can send them back for a different set. The problem is that the other set that they carry (in a 315/75/16) is Hankook MT and they are rated at 3858lbs but tread life is said to be 30k miles which is good for a mud tire but my truck rarely sees mud. Which would yall go with the Nittos at 3197 or the Hankooks at 3858 with less tread life. I need to make a desicion asap because I have ordered a set of them and I need to know to cancil or not. What does ford recomend lbs wise on the F250 anyway? THanks for the help!
