What is the difference between a 14 ply and a 16 ply truck tire?
Truck tires typically come in two load ratings: G and H. Load range G is a 14-ply configuration, while load range H tires have 16 plies. The heavier-rated tire will usually add between 700 pounds and 1,000 pounds more load-bearing capacity per tire (see “How Much is Too Much,” next page).
Is R or D better on trailer tires?
A radial tire flexes more than a bias tire, giving it better ground contact, traction, stability, and tread wear. A radial tire will normally run cooler than a bias ply tire, especially when the tire is under a load. A tire that runs cooler will last longer. For those reasons I would recommend an R tire over a D tire.
What the difference between a 235 80 and 235 85R16 tire?
Can 235/80R16 Tires be Used with 235/85R16 Tires on the Same Trailer Although they are similar in width, the 235/85R16 size tires are going to be almost an entire inch larger in diameter than the 235/80R16 size tires.
