Tire Safety

DOT Date Code 1303 with Sidewall Cracking

How much do you know about your tires? Do you know when they were manufactured? Do you know what size tires you have? Do you know the load and speed rating of your tires? Do you know what the tire pressure should be on all of your tires? Almost every answer to these questions is listed right on the tire.

For example, the date of manufacture is shown right after the DOT markings, and is shown as a four digit number with the first two digits representing the week of the year, and the next two digits representing the year. Therefore, the number 3615 would mean the tires were manufactured during the 36th week of 2015.

Tire pressure will be shown as recommended PSI cold, as “90 PSI Cold”. The load rating identifies the load carrying capacity, and typically is a value from 71 to 110. Each number represents a carrying weight capacity. A load rating of 87 equates to a load carrying capacity of 1201 pounds. The tire may also state specifically the load capacity in pounds, such as 4675. Charts explaining the codes are available on-line or from your tire dealer. The speed rating is similar with a code identifying the maximum speed at which the tires can be safely used. A speed rating of G equates to a 56 mph maximum. Again, specific charts can be found on the internet.

If you answered no to one or more of the questions above, you should look at your tires and find the answers. Your tires are one of the primary features of your RV that keep you safe while traveling. Not knowing about your tires and how to check them could present a major problem for you. It could jeopardize that trip you are so looking forward to. It only takes a few minutes to check your tire pressure before you start traveling for the day. Check also for any bubbles, cracks, or crazes in the sidewalls. Those few minutes could save you from a blowout or other tire failure.

When Quality RV Inspections by Art Horton LL,  performs an inspection, we inspect those tires and check all of the questions mentioned above. We want to make sure that when you take that RV out it will be safe for you and your family
