What is a good load index for tires?
The higher the tire’s load index number, the greater its load carrying capacity. Choosing a tire with a lower load index than the original equipment specifications means that the tire will not carry the load capacity of the original. Most passenger-car tire load indexes range from 75 to 100, but some are higher.

What does SL mean on a tire?

Standard load tires are manufactured mostly for regular passenger vehicles that are used for average, everyday driving and don’t need to carry or withstand heavy loads. Since they’re the most common passenger tires, they’ll either be marked with SL on the sidewall or nothing at all.
Are all LT tires 10 ply?
LT tires are usually 8-ply (Load Range D) or 10-ply (Load Range E). Passenger Tires usually have a 4-ply or 6-ply equivalent sidewall. The performance trade-off of this added weight is a harsher ride, less fuel efficiency, and less responsive handling.
Which is better 6 ply or 8 ply tires?
Actually the 6 ply will last longer than the 8 ply. The reason is the extra size of the body plies in a trailer tire will actually produce more heat while rolling than a 6 ply rated tire. I definately recommend radila and not bias ply construction. Radial tires wear much better.
