RV and motorhome tires age out before they wear out. Cracking in the sidewall or tread grooves means replacement, whatever the tread depth. For motorhome owners in Detroit, MI, Detroit Tire Shop can help match a replacement to the rig's weight rating. Call with your tire size and the load rating from the placard.
A motorhome may log a few thousand miles a year, then sit. That pattern is hard on tires: the weight presses on the same patch of rubber for months, the sidewall dries out, and the tread still looks nearly new. The tire is finished long before the wear bars say so.
The rig's weight is the other issue. A motorhome is heavy, and the tires have to be rated for the axle load with room to spare. Find the placard, usually near the driver's door or in the owner's manual, before you shop.
How do I know my RV tires need replacing?
Look at the sidewalls and the grooves between the tread blocks for fine cracks, and check for bulges or flat spots from sitting. Any of these is enough on its own. Then check the date code stamped on the sidewall, because age counts regardless of mileage.
What matters when I pick a replacement?
Match the size and the load rating on the placard, and do not drop below it. If the rig carries a lot of gear, ask whether the original rating still leaves enough margin once everything is loaded.
On dual rear wheels, the two tires on a side should be the same size and brand, and close in wear, so they share the load evenly. Mixed duals run hot.
What should I do before a long trip?
Check pressure cold, with a gauge you trust, against the placard figure and not the number molded on the sidewall. Inspect the inner dual too, which is the one people forget because it is hard to see.
If the rig has been parked for the winter, have the tires looked over before you load up and leave.
Can the shop work on a large motorhome?
Call ahead with the tire size and wheel setup so the shop can confirm it can handle your rig. Do not assume; ask.
Is it a problem if my RV tires have plenty of tread but look cracked?
Yes. Cracking means the rubber is breaking down, and the tread left on the tire does not offset it. Have it inspected before you drive any distance.
When can I bring the RV in?
The shop runs Mon–Sat 9:00 AM – 8:00 PM, Sun Open 24 hours. Phone first to confirm your tire size can be handled.
