Morning,
Will try to keep this as simple as possible.
Doing the investigation of new tires. I was completely convinced to go with either Duravis or XPS LT tires . My rig GVWR is 12.7 loaded with 6k axles. So by the book I should be using ST tires which have a carrying capacity of 3500 each vs 3000 on LT.
Several questions.
If my rig has a GVWV of 12,700 why are there only 6k axles?
Does keystone subtract the pin weight from what the tires/axles should carry?
Would I be over stressing LT tires with the weight above?
Also concerned with what I have read about 65 mph and overheating on ST's
I know all the discussion on LT vs ST, but the above questions are my main concern. As always I am probably over thinking this, but we still have 9 months to go and it occupies my time.. :-)
I would rather run LT's closer to their Max load capacity, than ST tires with a larger margin. They cost more for a reason. Many will state ST are designed to take the sidewall stress of the tandem axle. Well commercial HDT run the same tires on all axles, drivers and trailers. There are no ST's in big trucks.
