When to Replace RV Tires by Age: Inspect at 5, Replace by 10

Bottom Line Up Front

Eugene, your 2018-manufactured tires are now roughly seven to eight years old, and age matters more here than their 28K mileage or their good external appearance. Michelin's own RV/motorhome tire guidance is to have tires inspected by a specialist at least once a year after five years of service, and to replace them by ten years from the date of manufacture regardless of how they look. While your tire dealer is correct that they look good externally, RV tires face unique stresses from weight, UV exposure, and long periods of non-use that age them from the inside out. Your tires are well past the five-year annual-inspection threshold and heading toward the ten-year limit, so for casual RV use like yours, replacing all six now is the conservative, lower-risk call — and if you'd rather wait, at minimum have them professionally inspected before any long trip.

Root Causes

RV tires age differently than passenger car tires due to several critical factors. The constant heavy load of a motorhome causes continuous stress on the tire structure, even when parked. UV radiation from sun exposure breaks down rubber compounds over time, creating microscopic cracks that weaken the tire from within. Your motorhome likely sits stationary for extended periods, causing flat spots and uneven stress distribution that accelerates aging.

There is no single hard expiration date stamped on a tire, but age becomes the deciding factor once the tread still looks fine. Tire and RV-industry guidance generally treats five years as the point to begin annual professional inspections and ten years as the outside limit for replacement regardless of tread depth, because rubber compounds, internal belts, and sidewalls degrade with time and heat cycles even on low-mileage tires. Plenty of heavy-coach owners choose to replace a bit sooner — often in the six-to-eight-year range — as an added safety margin. With your 28K miles, these tires have spent far more time aging than wearing down through normal use, so tread depth alone is a poor guide to whether they are still safe.

Temperature cycling from seasonal storage and varying climates also contributes to tire aging. The combination of weight, time, and environmental factors creates a perfect storm for tire failure that external inspections simply cannot detect reliably.

Before You Start

Before shopping for replacement tires, gather your current tire specifications from the sidewall markings. You'll need the size (likely something like 275/70R22.5 or similar), load rating, and speed rating. Check your motorhome's door jamb sticker or manual for the exact specifications and required tire pressure. Document which position each current tire is in and take photos of any unusual wear patterns - this information will help identify potential alignment or suspension issues.

Research RV-specific tire dealers in your area, as regular tire shops often don't stock or understand motorhome tire requirements. Get quotes from at least three sources, including mobile tire services that can come to your location. Factor in mounting, balancing, disposal fees, and whether you need new valve stems (recommended with tire replacement). Budget approximately $2,400-$4,000 (rough ballpark — actual cost varies by region, brand, and model year and changes over time, so get current quotes) for a complete six-tire replacement depending on your tire size and brand choice.

Consider your replacement timing carefully - avoid peak travel seasons when tire availability might be limited and prices higher. Plan the replacement for when you'll be home for several days, as some services may need to order tires. If you must travel before replacement, keep speeds moderate, check tire pressure frequently, and avoid long driving days in hot weather.

The Repair Process

Start by choosing appropriate replacement tires designed for RV use. Brands like Michelin XRV, Goodyear G614 RST, or Bridgestone R250F are proven performers for motorhomes. Don't simply replace with the cheapest option - quality RV tires are a critical safety investment. Ensure the new tires match your motorhome's weight requirements and are manufactured recently (ideally within the past year).

Schedule replacement with a reputable RV tire service. Many offer mobile installation at your location, which is convenient and eliminates the need to drive on aging tires to a shop. The installation process should include removing all six tires, inspecting wheels for damage or corrosion, installing new valve stems, mounting and balancing new tires, and setting proper pressure according to your motorhome's weight distribution.

During installation, have the technician inspect suspension components for wear and check wheel alignment if equipment is available. Request that they dispose of old tires properly and provide you with documentation showing the new tires' manufacture dates. Ensure all tires are inflated to the correct pressure for your specific axle weights - this may require weighing your loaded motorhome at a truck scale.

After installation, plan a short test drive to verify proper installation and handling. Check tire pressures again after the first 50-100 miles, as new tires may settle slightly. Establish a regular inspection routine going forward, checking pressures monthly and visually inspecting for damage before each trip.

Professional Help Needed

This tire replacement absolutely requires professional installation due to the specialized equipment needed for large RV tires and wheels. Attempting DIY installation risks injury and improper mounting that could cause catastrophic failure. Professional RV tire services have the heavy-duty equipment to handle your motorhome's wheel and tire combinations safely.

Consider having a professional RV service center perform a complete chassis inspection concurrent with tire replacement. They can identify alignment issues, suspension wear, or brake problems that might affect your new tires' lifespan. If you discover uneven wear patterns on your old tires, professional diagnosis is essential to prevent premature new tire damage.

Mobile tire services are often the best option for motorhome tire replacement, as they eliminate the risk of driving on aged tires to reach a shop. These specialists understand RV-specific requirements and typically stock appropriate tires. Professional installation also includes proper balancing, which is crucial for motorhome comfort and tire longevity, and they'll ensure correct pressure settings based on your actual axle weights rather than generic recommendations.
