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 Flat Tire on Highway: Emergency Steps & Specialized Roadside Service Tips

Every highway mile seems to be eating through my Tiffin Allegro motorhome tires way faster than it should, especially after that brutal double blowout on the back axle. When this happened to us, we found that regular AAA and typical roadside assistance don't always help with RVs. We were stranded and eventually had to use a service called Driving Solutions, who charged us $1600 for used tires after eight hours of waiting.

What's the proper procedure if this happens? Should I try to move to a safer location first, or stop immediately? Who should I call for help - are there specialized services that handle RV tires? I want to be prepared with the right contacts and know the safe steps to take, because I imagine regular tow trucks and tire services might not have the equipment or expertise to handle a large motorhome tire emergency on the interstate. …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

Ford E-350 vs E-450 Chassis: RV Fuel Economy, Power & Weight Capacity

Last weekend I felt this awful engine strain and heard sluggish acceleration sounds while test-driving a 2017 Phoenix Cruiser #2351 with its E-350 chassis and V10 engine. I'll be doing extensive western touring through mountain and plains regions, which means substantial mountain grades and wind challenges. I'm comfortable driving slowly and want to understand two key things: 1) Will this E-350 chassis handle mountain grades without major issues, and 2) What's the real-world fuel consumption like? I plan to do an initial inspection this weekend, followed by a third-party mechanical review. I'm not overly concerned about fuel economy but want to understand the actual performance limitations. I'd appreciate insights from owners who have experience with similar touring conditions on an E-350 chassis. …more

RV Black Tank Not Holding Full Capacity: 7 Common Causes and DIY Repair Solutions

Somewhere between embarrassed and desperate, I have to ask this probably dumb question: why does my RV's black tank act full when it should hold way more? We have a 40-gallon black tank, but when I try to fill it with water for cleaning, it starts overflowing through the vent pipe at only 23 gallons. I'm afraid there might be something seriously wrong with the installation or that I could damage the system.

A professional cleaning service said the tank was completely clean with no blockages, so I'm confused about why it won't hold its full capacity. The water is definitely coming out the vent pipe, so I assume that means the vent isn't blocked? I'm hesitant to keep trying things without understanding what's actually causing this - could this be a safety issue or sign of improper installation? What should I be looking for to diagnose this safely? …more

Coleman Mach AC Fuse Blows With Battery On - Rockwood Fix

Coleman Mach AC Fuse Blows With Battery On - Rockwood Fix

Found out the hard way that the previous owner of my 2019 Rockwood Minilite 2509s left me with a Coleman Mach AC that blows fuses instantly when I flip on the battery. The AC fuse blows instantly when I turn on the battery disconnect, before the AC is even activated. The fuse literally blows before it's completely seated in the panel.

This began two weeks ago without warning - the system had been functioning normally prior to this. Initial fuse replacement provided temporary operation, but the problem returned on the next trip with the fuse already blown upon arrival.

Given the immediate fuse failure with just battery power connected, what type of electrical fault would cause this symptom pattern in a Coleman Mach unit, and what's the most likely location of the problem in the AC circuit? …more

How to Upgrade Your RV Converter Charger for Lithium Batteries with Gentle Care

Halfway through planning our three-week cross-country trip next month, I realized my PD4560 60-amp converter/charger won't properly handle the lithium batteries I'm installing. My existing Progressive Dynamics unit obviously isn't designed for LiFePO4 batteries - I can use boost mode to charge them up, but I know that's not ideal for battery longevity.

I just purchased a 30 amp generator and I'm wondering if it will have enough capacity to handle not just my current charger, but potentially a larger lithium-compatible unit. I'm considering upgrading to a 75 or even 90 amp charger to reduce charging times, but I need to make sure my generator can handle the load. I'm trying to figure out the actual AC amp draw of these higher-capacity chargers and whether my 30 amp generator will be sufficient.

What are the best lithium-compatible converter/charger options that would work with my generator setup, and how do I properly size the charger capacity to match my lithium battery bank? …more

RV Water Heater Not Hot Enough: Fix Lukewarm Water Issues

Looked forward to our two-week cross-country trip starting tomorrow until I discovered my RV water heater that used to produce scalding hot water now barely gets lukewarm. Both the electric and gas functions appear to be working - I can hear the gas igniting and see the electric indicator light - but the water temperature just won't get hot enough for a decent shower.

I've been dealing with this for weeks now and it's driving me crazy. The water gets warm, but nowhere near the hot temperatures I used to get. Is this a common problem with RV water heaters? What are the most likely culprits when you're getting lukewarm water instead of hot? I really need to figure out what's causing this and how to fix it before my next camping trip. …more

Fleetwood Excursion Tire Upgrade Guide: 255 to 275 Width Conversion

After upgrading my 2015 Fleetwood Excursion M-35B from 255 to 275 width tires, it started getting sketchy handling on highway turns. The current 255/70R22.5 tires are wearing out and I'd love to go wider with 275/70R22.5 for better stability, but I keep getting conflicting advice from different tire shops.

Some say it's fine, others warn about clearance issues and potential problems. I really need to know what specific measurements I should check before making this change. What wheel width do I need? How do I verify there's enough steering clearance? I don't want to buy expensive tires only to find out they don't fit properly or aren't safe for my RV's load requirements. …more

RV AC Making Loud Humming Noise? Fix Compressor Not Starting

Somewhere above my head, there's this loud, relentless humming grinding through the RV whenever I flip on the rooftop AC — compressor won't start but the fan spins fine.

I've been dealing with this for days now and it's driving me crazy - especially with the heat we've been having! The humming is so loud that I'm worried something might be seriously damaged. I really hope this is something I can fix myself rather than having to call out a repair tech. What could be causing a compressor to hum loudly but not start up? …more

MagnaSine MS2012 Inverter Replacement Guide - Best Upgrade Options 202

About my 2007 Fleetwood Bounder: the MagnaSine MS2012 manual claims it should handle my loads perfectly, but this inverter keeps failing on me anyway. It's been acting up for months now - the microwave keeps causing it to hiccup and shut off, then it comes right back on. I know it's only going to get worse from here.

I've been looking at upgrading to something more reliable, maybe a Victron or another brand, but I'm honestly overwhelmed by all the options out there. What are the best replacement inverters that other RVers have had success with? I just want something that's going to work consistently without all these random shutdowns.

Before I spend a bunch of money though, could this actually be a battery issue instead of the inverter itself? I'd hate to replace a perfectly good unit if the real problem is somewhere else in the system. …more

How to Protect Your RV Alternator When Charging Lithium Batteries: DC-

Tried everything my neighbor did to charge his LiFePO4 batteries but mine keeps frying the alternator while his works flawlessly — what's different? I want to install a temperature sensing device that can interrupt charging by opening the solenoid between chassis and house charging systems if the alternator gets too hot. I'm looking to spec out components and understand the installation process, and I'm open to hearing why this might not be a good approach. My goal is preventing alternator overheating when these lithium batteries draw high current compared to my old flooded or AGM batteries. I'm looking for technical feedback and am totally open to critique. …more
