The Tire Problem Nobody Talks About
RV tires fail differently than car tires. A passenger car wears out its tires in 40,000 to 60,000 miles. An RV that travels 5,000 miles per year may still have full tread after 10 years — but the rubber has aged beyond safe use. UV exposure, ozone, temperature cycling, and the weight of the RV sitting on one spot during storage all degrade the rubber compound from the inside out. The tire looks fine on the surface but has lost the flexibility needed to handle heat and load at highway speed.
The second most common cause of RV blowouts is underinflation. A tire that is 20% low on pressure generates significantly more heat in the sidewall during highway driving. Combined with a hot summer day and a fully loaded RV, that heat buildup can trigger a catastrophic sidewall failure in as little as 30 minutes of driving.
Tire Inspection Services We Provide
1 DOT Date Code Verification
We read the DOT date code on every tire — including the spare and inner duals that are hard to see — and tell you exactly how old each tire is. Tires older than 5 years get a close inspection for aging signs; tires older than 7 years get a replacement recommendation regardless of tread depth.
2 Tread Depth & Wear Pattern Analysis
We measure tread depth at multiple points across each tire. Uneven wear patterns reveal alignment issues, overinflation (center wear), underinflation (edge wear), or suspension problems (cupping or scalloping). Catching these patterns early can save you from premature tire replacement and point to underlying mechanical issues.
3 Inflation Pressure Check & Load Assessment
We check inflation pressure on all tires when cold and adjust to the correct pressure for your RV's loaded weight. The correct pressure is not always the maximum printed on the sidewall — it depends on the actual weight each tire carries. We discuss proper inflation practices and the importance of checking pressure before every trip.
4 Sidewall & Valve Stem Inspection
We inspect sidewalls for weather checking (fine cracks from UV and ozone exposure), bulges (indicating internal structural damage), scuffs and cuts from curb contact, and dry rot. We also inspect valve stems for cracking and corrosion — rubber valve stems degrade with age just like the tire itself and are a common slow-leak source.
5 TPMS Installation
We install wireless tire pressure monitoring systems that give you real-time pressure and temperature readings on a dashboard display while driving. A TPMS alerts you to a slow leak or overheating tire before it becomes a blowout — giving you time to pull over safely. We install sensors on all tires including the trailer and spare.
Frequently Asked Questions — RV Tire Safety Inspection
How old can RV tires be before they should be replaced?
Most tire manufacturers and the RV Industry Association recommend replacing tires after 5 to 7 years regardless of tread depth. Rubber degrades from UV exposure, ozone, and temperature cycling even when the tire is not being used. RVs that sit in storage for months between trips are especially susceptible because the tires age without wearing. The DOT date code stamped on the sidewall tells you the week and year of manufacture — we check this on every inspection.
What causes RV tire blowouts?
The leading causes are underinflation (which causes heat buildup in the sidewall), overloading (carrying more weight than the tire is rated for), aged rubber that has lost its flexibility, and UV damage from sun exposure during storage. Many blowouts happen on the first hot-weather trip of the season — a tire that was marginally underinflated all winter overheats on a 75-degree day at highway speed.
How do I read the DOT date code on my RV tires?
The DOT date code is a four-digit number at the end of the DOT identification string on the tire sidewall. The first two digits are the week of manufacture and the last two digits are the year. For example, 2319 means the tire was manufactured in the 23rd week of 2019. If your tire only has a three-digit code, it was manufactured before 2000 and should be replaced immediately.
Should I install a tire pressure monitoring system on my RV?
Yes, we strongly recommend it. A TPMS monitors pressure and temperature in real time while you drive and alerts you to a low tire before it becomes a blowout. RV tires are particularly vulnerable because they carry heavy loads and the driver cannot feel a slow leak the way they might in a passenger car. We install wireless TPMS systems that cover both the tow vehicle and trailer.
What tire pressure should I use for my RV?
The correct pressure depends on the actual weight on each tire, not just the maximum pressure printed on the sidewall. We recommend weighing your RV loaded for travel and inflating to the pressure specified in the tire manufacturer's load and inflation tables for that weight. Overinflation causes a harsh ride and center-strip wear. Underinflation causes heat buildup, sidewall flex, and blowout risk.
