All wheels are rated for maximum load & inflation pressure. These ratings
must be compatible with the tire ratings. It is dangerous, for example, to mount
a tire rated at 3,000 pounds on a wheel rated at 2,000 pounds. If ratings are
not marked on the wheel, check with the vehicle manufacturer & the wheel
manufacturer for proper identification. Don’t automatically assume that the
wheels are suitable for the tires, particularly if you are buying replacement
tires.
Two other situations require the same careful inspection. One is buying
trailer tires & the other is buying radial tires to replace bias ply tires. In
both cases, careful matching of tires & wheels can prevent serious issues &
add to your RV enjoyment.
