How long do RV tires last? What are RV tires age limits? When should they be replaced? These questions are crucial to ensure your safety on the road.

In this guide, we’ll answer these and more, providing key insights into RV tire lifespan and how to extend it. Before embarking on your next adventure, make sure your tires are as prepared as you are!

How Long Do RV Tires Last?

RV tire lifespan is not fixed and depends on several factors. Generally, RV tires last between 5 to 7 years. However, with proper maintenance and care, some RV tires can be safely used for up to 10 years. Unlike passenger vehicle tires, RV tires may not show significant tread wear before reaching the end of their lifespan. 

Factors Affecting RV Tire Longevity

Mileage vs. Tire Age: Most RV tires do not wear out significantly in terms of tread before they reach the end of their lifespan. This is because RVs are not usually driven continuously for long periods. 

Rubber Aging: Rubber can dry out and develop cracks over time, especially if exposed to sunlight or stored for long periods. Such cracks in the sidewall indicate that the tire’s structural integrity may be compromised, increasing the risk of a blowout.

When to Replace Your RV Tires?

Dry Rot: Dry rot occurs when the rubber loses its elasticity and cracks, typically due to prolonged exposure to sunlight or long-term storage. Small cracks on the sidewall indicate that the tire's structural strength has been compromised, posing a blowout risk.

Tread Wear: Although RV tires wear more slowly, they should be replaced if the tread has worn down to the legal minimum depth, generally 2/32 inch or about 1.6 mm.

Sidewall Damage: Visible scratches, cracks, or bulges on the tire sidewall, especially from impacts with curbs or obstacles, suggest that the tire should be replaced.

Abnormal Vibration: If you experience unusual vibrations while driving, it could indicate a problem with the tire or suspension system that requires immediate inspection and resolution.

Checking Tire Production Date (DOT Code)

The production date of RV tires is crucial for determining when they need replacement. Each tire sidewall contains a "DOT" code, with the last four digits indicating the production date. For example, the code "1420" means the tire was made in the 14th week of 2020. Tires are generally recommended for replacement within 5 to 7 years, even if the tread and appearance are still good.

DOT Code: Since 2000, all tires have this code, helping owners easily determine the tire’s actual age. Regularly check the DOT code on each tire, as tires replaced at different times may have different production dates.

How Long Do Michelin RV Tires Last?

Michelin suggests that RV tires should be inspected annually by a professional starting 5 years after production, even if there are no visible signs of wear or if the tread has not reached the wear indicators. Michelin recommends that tires not be used for more than 10 years, including spare tires, regardless of their usage.

This precautionary replacement policy helps ensure vehicle safety by mitigating the risks associated with tire aging. Regular inspections and adhering to the 10-year replacement guideline can prevent potential safety issues related to tire deterioration.

How Long Do Goodyear RV Tires Last?

Goodyear recommends replacing any RV tires that are over 6 years old, even if they appear to be in good condition. This recommendation applies to all tires installed on the vehicle, including spares, regardless of whether they have been in regular use. The rationale behind this is that over time, tires can be exposed to adverse environmental conditions that increase the risk of aging and damage, even if the tread has not yet reached the legal wear limits.

Additionally, Goodyear advises users to rely on the tire's DOT code to determine its production date if the original usage date is unknown. Based on this production date, you should replace the tire within 6 years to ensure safety and performance.

How Long Do Carlisle Trailer Tires Last?

The lifespan of Carlisle trailer tires, like other trailer tires, is typically 3 to 5 years, regardless of mileage. While these tires may still have adequate tread, they can wear beyond safe use due to the significant weight they support, even when not in motion.

Several factors affect the longevity of Carlisle trailer tires:

• Static Weight and UV Exposure: Tires that sit in storage under static weight and exposed to UV light can deteriorate faster than those in use.
• Load Management: If one tire fails, the remaining tires must suddenly bear the increased load, which can lead to overloading and potentially a chain reaction blowout.
• Usage Conditions: High-speed towing, especially in hot conditions, significantly degrades tire performance. It's best not to exceed 60 mph while towing, as most ST trailer tires have a maximum speed rating of 65 mph. Higher speeds increase heat and stress, reducing load capacity and overall tire life.

Best Practices:

• Inspect all tires after a blowout to check for damage and replace all tires on the affected side.
• Consider replacing tires after three years, even if they still have tread, as about one-third of their strength may be gone by that time.
• After five years, it is recommended to replace trailer tires regardless of tread depth to ensure safety.

Are 10-Year-Old RV Tires Too Old?

Yes, 10-year-old RV tires are generally considered too old. While tires may still look fine with proper maintenance, the materials degrade over time, compromising their structural integrity. The commonly recommended lifespan for RV tires is 5 to 7 years, and even if they appear to be in good condition at 10 years, it’s safer to replace them.

When evaluating tires, consider the following points:

1. Check the DOT Code: The DOT code on the tire sidewall includes the manufacturing date, with the last four digits indicating the week and year of production. Tires older than 10 years should be replaced regardless of appearance.
2. Look for Dry Rot and Aging: Even if the tread depth is acceptable, signs of dry rot and aging can significantly affect safety. If you notice cracks on the sidewall, especially deeper than 1/16 inch, it’s time for a replacement.
3. Professional Inspection: Regularly having a professional tire technician inspect your tires is crucial for ensuring their safety.

How Many Miles Do Trailer Tires Last?

1. General Estimates: While some sources claim that RV tires last between 10,000 to 15,000 miles, this range is often based on anecdotal evidence rather than concrete data. Actual mileage can be affected by how frequently and under what conditions the RV is used.
2. High-Mileage Travelers: For RV owners who travel extensively, such as those who accumulate 10,000 miles or more per year, the expected lifespan of trailer tires may extend beyond the lower estimates. Many users report their tires performing well beyond 20,000 miles, and some even up to 30,000 miles or more, provided they are well-maintained.
3. Age vs. Mileage: It’s important to note that tire age is a critical factor in determining when to replace them. Regardless of mileage, RV tires should generally be replaced every 5 to 7 years. Regularly checking for signs of wear, dry rot, and other damage is essential for safety.

In conclusion, while the 10,000 to 15,000 miles range is often cited, many factors come into play. For high-mileage RV travelers, aiming for a tire replacement around 25,000 miles or after 2.5 to 3 years of travel may be a more prudent strategy, but always prioritize tire age and condition.
