RV and motorhome tires are chosen by the weight the coach carries, not just the size printed on the old tire. Before calling Oklahoma City Tire Shop in Oklahoma City, weigh the loaded rig, read each sidewall's size and load range, and check the date code on every tire, spare included.
The old tire tells you the size. It does not tell you whether that size was right. A motorhome gets loaded with water, gear and sometimes a tow vehicle, and the load range has to cover the heaviest corner, not the average.
Plan the visit like a trip. The shop at 1444 SW 25th St in Oklahoma City runs Mon–Fri 8:00 AM – 7:00 PM, Sat 8:00 AM – 6:00 PM, Sun 10:00 AM – 2:00 PM, so settle a time by phone, and ask about parking and clearance for a tall coach before you drive over.
How do you find the right load range for a motorhome?
Start with the tire and loading sticker, usually near the driver's door, which lists the tire size and the pressure the manufacturer intended. Then take the rig, loaded as you travel, to a public scale and weigh each axle.
Inflate to suit the heaviest axle. An RV that runs on pressures set for an empty coach is carrying its weight on soft sidewalls.
Should every tire be replaced at once?
On a dual rear axle, two different tire heights mean the taller one carries more. Match the pair, and match them to the other tires on the axle where you can.
Age matters as much as tread. If one tire failed from old rubber, the rest bought the same day are no younger.
What about the spare and everything you tow?
A spare on the back rarely turns over, so it is often the oldest tire on the rig.
- The spare, including its date code
- The tires on a car or trailer you tow
- Pressure after long storage, which should be rechecked before the first trip
Do motorhome tires wear out while parked?
They can age and develop flat spots without turning a mile. Sun and low pressure speed the damage, so keep them covered and inflated. Inspect the sidewalls before a trip rather than trusting the tread.
Can I replace only the tire that failed?
Sometimes, if the rest are near the same condition and size. Ask about the height difference on a dual axle, and check the age of the remaining tires before agreeing to a single replacement.
