TIRES
Tires are available in a variety of load ratings and sizes, and if the tires you currently have cannot
handle the load, it may be possible to replace your tires with tires of higher pound capacity. Keep in
mind, that the ultimate capacity of the tow vehicle is determined by the weakest link in the system.
This could be the tires, wheels, suspension or brakes. The maximum ratings are molded into the side
of the tire. The sidewall of the tire shows maximum and minimum inflation pressure for that load.
Be sure you also know the load and inflation pressure ratings for your wheels as well. Often, these
are stamped on the inside of the wheels, but if not, your dealer can help you find out what they are.
Never exceed the maximum load or inflation pressure of your wheels. Driving on under-inflated tires
can cause the tires to overheat, which leads to the breakdown of the tire’s internal structure. Improper
inflation also can reduce your ability to control your vehicle. Tire blowouts occur more during
summer months than any other time of the year. Properly inflated tires last longer, run quieter, grip
better, increase fuel mileage and safely support and control your vehicle. Check your tire pressure
once a month and each time before you take a trip with your truck and camper. Use a quality air
pressure gauge to check the pressure. Do not under-inflate or over-inflate your tires. Inspect your
tires for uneven or excessive wear. Look for bulges, cuts, or blisters on the sidewalls. When you’re
traveling, do as professional commercial drivers do: inspect your tires regularly and check and adjust
cold inflation pressure every day that you travel.
CAUTION Individual wheel position weights must not exceed the maximum tire load capacity.
Maximum tire load capacity can only be achieved utilizing the maximum allowable psi as listed on
the sidewall of the tire.
