Had a tire slashed a couple weeks ago. Can only hope it was a neighborhood kid who was bored and not someone mad at me.... I had a nice set of 4 evenly worn Yokohoma H/T 265/75/16s and was really happy with them. A new one is $200+ installed and short on funds at the moment so in my haste I bought a 265/75/16 tire for $65 on fleabay and a local shop will mount and balance for $10. Well it got here and its only a 7 ply tire. Think its safe to run in the meantime? I won't be towing with this truck until I get a 10 ply back on but I figure a 7 ply and put it on the rear and should be okay? What do you guys think. I only drive the truck around town for errands for the most part.
Here is the one I bought. Still has the dimples on the top so its basically new.
Tires generally aren't rated in plies anymore. Instead they have load range ratings. F-350s generally have load range E tires, which corresponds to the old 10 ply rating. But there are a lot of load range E tires now with less than 10 plies.
So the question is what load range is the tire you're asking about? If it's load range E you're golden. If it's D you're probably OK too. If it's C I wouldn't suggest loading the truck down too much.
I didn't do a whole lot of research on the LT vs P thing but what I did read seemed confusing. And from what I read P does stand for passenger and is a metric measurement?? Supposedly Ps could be a C or D rated tire.... it all sounds sketchy to me but I already forked over the $$$. I am going to run it in the rear for now. I figure its better than the dry cracked all-terrain tire with basically no tread on one of the 6.5 inch steelies I have for a spare.
I will buy a new yokohoma within a couple months and I won't tow with the truck until that time.
Well I generally run the tires at 50 psi all around since I was getting even wear and I hardly tow so didn't need max load. I read on the lower weight rated tire the psi will be different for the same load capacity. If the tire is only rated for 1700lbs vs 3000lbs for a load range E so what roughly 56% of load capacity of the E tire. I am not sure what PSI to run it at but should probably be closer to the max side of 1700 since the sidewall on the E tires are much thicker even though with the PSI in them I am not using the full 3000lb capacity. Or at least I would think. Feel free to correct my logic.
I need to check what the max PSI on the tire is. Its cold out in the garage though.
