All wheels are rated for maximum load and 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 and 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 and the other is buying
radial tires to replace bias ply tires. In both cases, careful matching of tires and wheels can prevent serious
issues and add to your RV enjoyment.
