Check Your RV Tires Beyond the Tread
Read tire date codes, check every wheel position and spare, spot warning signs, and build a practical inspection plan before your next RV trip.

Plenty of tread does not tell you everything about an RV tire. Before your next trip, find out when each tire was made, look for damage and check whether an inspection or replacement is already due. Include the spare. A tire that spends most of its life parked still needs attention.
This is a job to do before travel day, while you have time to get help. You will finish with a record for each tire and a clear next step for anything questionable. You are not trying to certify a tire as safe with a flashlight; you are finding the problems and missing information that deserve attention before the rig moves.
Start with a place for every tire
Draw a simple outline of your rig and label the tire positions as viewed facing forward. For a tandem-axle trailer, use left front, right front, left rear and right rear. Add a separate line for the spare. A motorhome with dual rear wheels needs separate entries for the inner and outer tires, not one entry for the whole pair.
If you tow, make a second list for the tow vehicle and its spare. Keep the two lists together so the trailer does not receive all the attention while the truck gets overlooked. A notes app or a sheet of paper is enough; the useful part is being able to connect a photograph or service finding to the correct tire.
Work on firm, level ground with the vehicle secured against movement according to its manual. Stay clear of traffic. Do not crawl under the RV or rely on leveling jacks to gain access to a hidden date code. If a sidewall cannot be reached safely, put “needs shop check” in that position’s record.

Read the date, not just the receipt
Find the DOT Tire Identification Number, often shortened to TIN, on the sidewall. For tires manufactured since 2000, the final four digits give the production week and year. A code ending in 2321 means the tire was made in the 23rd week of 2021. It does not mean March 2021, and it is not an expiration date.
The complete code may be on the other sidewall. If you see DOT markings but cannot find the date, do not choose another four-digit number that happens to be nearby. Ask the tire shop to locate and record the complete TIN. Save a clear photograph when you can do so safely.
Keep manufacture and installation dates in separate fields. For example, a tire made in 2021 and installed in 2023 does not become a 2023 tire. The receipt helps establish when it entered service; the sidewall tells you when it was produced. Write “unknown” for a missing installation date rather than treating the day you bought a used RV as the tire’s first day of service.

Find the guidance for your actual tires
Look up service-life guidance for the tire brand and product, along with the RV or chassis manufacturer’s instructions. Save the relevant document or link beside your tire record. A warranty period describes coverage; it is not a promise that the tire remains safe for that many years.
Michelin’s RV guide provides a useful example of two different clocks: tires in service for five years or more should receive at least annual inspections by a qualified tire specialist, and tires ten years or older from manufacture should be replaced as a precaution, including spares. These are Michelin’s recommendations, not a universal RV replacement schedule or permission to keep any tire for ten years.
Condition, use and the vehicle’s instructions can require action sooner. Ask your tire professional which guidance applies if you have mixed brands, incomplete records or conflicting recommendations. Record the answer with a date. “Check again next season” is less useful than a specific inspection due date and the reason for it.

Look for changes around the whole tire
Use good light to examine the accessible tread and sidewalls. Look for cuts, cracking, bulges, exposed cords, embedded objects and uneven wear. Include the valve stem, valve cap and wheel in the walk-around. Airstream’s inspection guidance specifically includes these areas before trips and after extended storage.
Describe what you see rather than diagnosing it yourself. “Cracks near the right rear sidewall lettering” or “wear concentrated on the inside edge” is useful information for a technician. Take a photo from a safe position and mark the tire’s location. Do not pull out an embedded object to see how deep it goes.
Check tread depth as part of the inspection, but do not let one good measurement end the job. The correct service decision also depends on damage, age and the requirements for that vehicle and tire position. A tire that looks clean and has deep grooves can still have a problem you cannot see.

Some findings should stop the departure
A sidewall bulge is not something to watch over the next few trips. Michelin says it indicates damage and cannot be repaired; the tire needs replacement. Do not drive on a damaged tire to reach the shop. Arrange qualified assistance, including roadside tire service when needed, and use a spare only if it is suitable and can be installed safely.
Repeated pressure loss, a new vibration or a change in handling also deserves professional attention. Tell the technician when it started, whether there was a curb or pothole impact and whether the tire was driven while low or flat. Adding air does not establish that a previously damaged tire is fit for travel.
If a concern appears while driving, slow down in a controlled way and stop somewhere safe. Do not inspect a traffic-side tire while exposed to passing vehicles. Contact roadside assistance from a safe location and explain that you have an RV, its approximate dimensions and the affected wheel position. Avoid turning a tire problem into a roadside injury.

Give the spare a real inspection
An unused spare is still a tire with a manufacture date, storage history and inflation requirement. Check its condition and pressure using the applicable vehicle and tire instructions. If a cover or carrier makes it difficult to inspect, arrange access before the trip rather than discovering the problem beside the highway.
Also confirm what the spare can actually do. Ask whether it is suitable for the tire position you might need, and what restrictions apply. A motorhome dual-wheel arrangement or a temporary spare can complicate a casual assumption that “we have a spare” means the problem is solved.
Note where the carrier tool and instructions are kept, and whether your roadside service handles your rig and tire size. That is preparation, not a recommendation to change a heavy RV wheel yourself. If the spare is unsuitable or unusable, make the service plan explicit before leaving.

Use the complete identity for recall checks
Save the brand, tire line, size and complete TIN, not only the four date digits. Those details help establish whether a recall applies. NHTSA’s recall site offers tire searches; a vehicle VIN search alone should not be your entire tire check, particularly after replacement tires have been installed.
Read the affected-tire details and manufacturer instructions for any matching result. If the identification is unclear, ask the tire maker or dealer to confirm it before deciding the tire is unaffected. Follow any interim safety instructions in the recall. A broad search result is a starting point, not a personalized clearance for your particular tire.
Keep installation invoices and inspection findings together. When a tire moves to a different position, update the map rather than leaving its history attached to the old corner. After replacement, record the new tire’s actual code and ask the seller about tire registration so recall notices can reach you.

Leave yourself a short, usable action list
Finish each tire’s entry with an action: no unresolved finding noted today, professional inspection needed, replacement due under the applicable guidance, or identification still missing. The first entry is a record of your check, not a guarantee of future safety. Give unresolved items an owner and a date before departure.
Before storage, save the current condition and pressure readings so you have something to compare when the RV comes out again. Use the tire and vehicle makers’ storage instructions. Protection from sun and weather is helpful care, but a cover does not reset the manufacture date or remove the need for inspection.
On travel day, complete your normal cold-pressure and walk-around routine as well. This age-and-condition check adds the history that a pressure gauge cannot provide. The useful outcome is knowing what is on every wheel, what needs attention and who will handle it before the next mile.
