There are many reasons that will answer this question. Probably the most important reason is safety. That’s the short answer; road safety. Other reasons include how proper tire pressure can help with gas mileage, increase the life of the tire, and could help prevent blowouts. Damage can occur if tires are inflated too much, as well as underinflated. Checking the air pressure is an easy chore; But, if you aren’t sure what number the pressure should be, the proper psi is stamped on the sidewall of all tires.
When to Check
RV tires come with a recommendation of inspections every 90 days. Checking the tires to see if they need to be replaced and inspecting the wear of the tread should be done every three months to ensure safety. However, many do not wait that long. In a way to practice the adage, ‘better safe than sorry’, many will check the tire’s pressure and tread before heading out on the open road. Here are three tips for keeping up with proper tire maintenance.
- When you check the tire pressure of the tires on the vehicle, don’t forget to check the spare.
- With an RV that has a gross vehicle weight rating (GVWR) of more than 10,000 pounds, the front tires should be replaced when the groove is worn down to a 4/32” depth.
- Many tire companies recommend tire rotation every 5,000 miles.
