Michelin RV Tire Problems: Complete Guide & Solutions 2024

Standing in my driveway planning to tackle these serious handling issues with my new Michelin Agilis HD Z 245/70R19.5 tires on my 2018 Winnebago Vista LX 27N this Saturday — what should I check first? The RV now has 25k miles, and since switching from Goodyear tires, I'm experiencing terrible tail wag - especially when towing my 2024 Toyota Tacoma and in windy conditions.

I've tried multiple tire pressures (82 psi from door sticker, 110 psi from installer, up to 100 psi) but nothing resolves the side-to-side movement. I have several stability modifications installed (Rear Trac Bar, Aux Roadmaster Rear Swaybar, Front Roadmaster Swaybar, Koni FSD shocks), which previously helped with handling.

The movement feels like the towed truck is actually pushing the RV's rear side-to-side, making driving extremely uncomfortable. I'm within Michelin's 60-day/2500-mile buy-back period and want to understand why these tires are performing so differently from my previous set.

Could experienced RV owners help me diagnose what might be causing these handling problems? …more

RV Tire Replacement: When to Replace by Age - Complete 7 Year Rule Guide

Pulled into three different tire shops asking about RV tire replacement and got three completely different answers about when tires actually need replacing. The unit has six tires with 2018 DOT date codes, making them 7 years old as of 2025. Mileage is approximately 28,000 miles, and visual inspection shows good tread depth with no apparent cracking, bulging, or other visible deterioration.

A tire technician who performed my state inspection indicated the tires appear serviceable from an external assessment standpoint. However, I understand there may be internal degradation factors not visible during standard inspection procedures.

What is the technical consensus on replacement timing for RV tires when age limits are reached but visible condition remains acceptable? Specifically looking for guidance on the 6-7 year replacement interval and whether internal rubber compound deterioration poses legitimate safety risks regardless of external appearance. …more

RV Tire Age Limits: Why Replace Michelin Tires After 7 Years Despite Good Tread

Called three different tire shops this month about my 2020 Newmar Ventana's Michelin 275/70R22.5 tires and all want them replaced just for being 6 years old despite perfect tread. I'm meticulous about tire maintenance - I check air pressure religiously before and after every trip, whether it's a short weekend getaway or an extended cross-country journey like the 5000-mile trip I just completed.

Despite my careful maintenance routine, I experienced a blowout on the right rear inside tire during the final leg of that recent long trip. When the roadside service technician came out to help, he recommended replacing all six tires specifically because of their age, even though the remaining tires still have plenty of tread depth and appear to be in excellent condition visually.

This has me confused because I've heard conflicting advice from other RV owners - some say well-maintained motorhome tires can safely last up to 10 years, while others insist on much shorter replacement intervals. I'm trying to understand what the actual safety guidelines are for RV tire replacement based on age versus tread wear. Should I really replace tires that still look good just because of when they were manufactured? What's the real story on how tire age affects safety, and how do I properly check the manufacturing date to make this decision? …more

Toyo vs Michelin RV Tires: Complete Comparison for Diesel Pusher Motorhomes

Planning to replace the tires on my 2019 Tiffin Phaeton 40IH, and ever since I started getting quotes, everyone keeps suggesting Toyo as a cheaper alternative to Michelin.

I'm honestly a bit overwhelmed by all the tire choices and wondering if I'd be making a mistake switching brands. Will Toyo tires give me the same ride quality as the Michelins? I've heard you can save quite a bit of money, but I don't want to compromise safety or comfort since we're still learning how to handle this big rig.

Would really appreciate some guidance from those who've made this switch - are you happy with the decision or do you regret not sticking with Michelin? …more
Toyo M-156 RV Tire Review: Replacing M-154 Steering Tires

Toyo M-156 RV Tire Review: Replacing M-154 Steering Tires

After 50,000 miles, my Class A motorhome's 245/75R22.5 M-154 steering tires have uneven wear, sidewall cracks, AND are losing air pressure weekly. I've been running the Toyo M-154s for years and have been extremely satisfied with their performance, durability, and overall quality. However, I recently discovered that Toyo has discontinued the M-154 model and replaced it with the M-156.

From what I can see, the M-156 has a completely different tread pattern compared to the M-154, and I'm concerned about how this might affect performance. Specifically, I want to know if the construction quality and load ratings remain the same as the M-154, since those have been rock solid for me. I'm also curious about the road noise characteristics - the M-154s were reasonably quiet, but I'm wondering if the new tread design on the M-156 creates more or less road noise. Additionally, since this is a steering tire replacement, I want to confirm the proper replacement approach and whether there are any specific considerations I should keep in mind when switching from the M-154 to the M-156 design. …more
