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 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

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

SDI E-Clik vs Liquid Spring: Affordable F53 Chassis Suspension Upgrade Options

Nobody warned me that what started as minor swaying on highway trips last month would turn into white-knuckle driving every time I take my F53 chassis RV over 50mph. SDI E-Clik costs about a third of what Liquid Spring systems run, but I'm wondering what you actually get for that price difference.

Is E-Clik just electronic shock control, or does it offer more comprehensive suspension improvements? How does the ride quality compare between the two systems on F53 motorhomes? …more

How to Fix Dutch Star Front Air Bags That Won't Inflate - Height Valve Troubleshooting

I replaced my 2006 Dutch Star height valve but the front air bags still won't inflate, the valve seems stuck, AND the whole front end is sitting way too low. The air pressure gauges look totally normal, but when I try to air up the front bags, they just won't fill up. Instead I'm hearing this whining noise and air is literally coming out of the height control valve exhaust port.

It's like the system thinks something's wrong but I can't figure out what. The bags themselves seem fine, and there's definitely air pressure in the system. What would cause the height valve to dump air instead of letting the bags inflate? This is driving me nuts! …more

Ford F53 Godzilla V8 Suspension Problems: Fixes & Upgrades for Class A Motorhomes

Halfway through my first long trip, this bone-rattling vibration and unsettling sway started plaguing my newer Class A motorhome with the Ford F53 Godzilla V8 chassis. Coming from a 26' travel trailer and a history with brands like LazyDaze, I'm trying to understand the current RV landscape. I saw a Baystar 2023 model where the owner spent around $35,000 on suspension upgrades after just 12,000 miles.

Sounds awesome on paper, but I keep hearing people say you still need to dump a ton of money into suspension upgrades to make these things handle decently on the highway. Did Ford actually improve the suspension setup when they introduced the Godzilla engine, or are we dealing with the same basic chassis design that's been around forever? I'm talking about 30+ foot Class A rigs here - seems crazy that a $200k motorhome would need immediate aftermarket work to drive safely.

Anyone know if the Godzilla F53 combo actually fixed the handling problems or if it's just more power on the same wobbly platform? …more

Balance Beads with Internal TPMS Sensors - Real Experience

Since it's 2 AM and I need to hit the road at dawn, I'm desperately trying to figure out if balance beads will interfere with my RV's internal TPMS sensors. I keep reading about how great balance beads are for eliminating wheel vibration, but I'm terrified of damaging those expensive TPMS sensors inside the wheels.

What if the beads hit the sensors and break them? Or interfere with the signal? I can't afford to replace TPMS sensors if something goes wrong. Has anyone actually done this successfully, and are there special precautions I need to take with bead size or how they're installed? I need to know this is safe before I risk it. …more

Onan 5500 Generator Tune-Up Guide: Best Aftermarket Parts & Filters 20

Before my last camping trip when I tried to order replacement parts, I discovered that finding genuine OEM components for my Onan 5500 generator has become nearly impossible. The Cummins website has been showing most tune-up components as out of stock for months now, and when I do find supposedly "official" Onan oil filters online, many retailers are substituting generic filters that may not meet the same specifications.

I've been researching alternatives and I'm particularly concerned about getting the right oil filter and spark plugs. For the oil filter, I've seen conflicting information about whether aftermarket options like Wix filters are truly compatible - some sources mention the 57398 but I've read mixed reviews about fitment issues. For spark plugs, my current ones are NGK BPR4EY, and I've heard the NGK 3432 might be equivalent, but I want to make sure before ordering.

I'm also planning to stick with zinc-containing oil like Rotella T6 15w40 since I know air-cooled engines need the extra protection, but I'd love confirmation that I'm on the right track with quality aftermarket parts that won't compromise my generator's performance. What specific part numbers and brands would you recommend for a reliable tune-up when OEM parts aren't available? …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

Ford E-450 Motorhome Alignment: Complete Caster Adjustment Guide for RVs

After following the Ford manual's factory alignment specs on my 2019 E-450 chassis, this house-on-wheels still wanders like a drunk tourist in Vegas. I'm pretty sure it needs a caster adjustment, but I'm confused about the actual process.

Do I need cam bolts or shims to adjust the caster on an E-450? And what's the sweet spot for positive caster degrees to keep this beast tracking straight? Also heard something about toe adjustments being important after messing with caster - is that really necessary or just another way for the shop to separate me from my beer money? …more

How to Find the Correct Tire Pressure for Goodyear Fuel Max RSA RV Tires

Before, my old Class C worked fine with the dealer's generic tire pressure chart — but these new Goodyear Fuel Max RSA 245/70R19.5 load range H tires on my 2008 Winnebago Sightseer 29R are completely different. My loaded RV weighs 6,020 lbs on the front axle and 11,220 lbs on the rear axle based on my most recent scale weights.

I'm concerned that 100 PSI might be too high since my previous Goodyear G670RV tires ran fine at 85-90 PSI, and the handling feels different now, especially when towing. I want to make sure I'm running the correct tire pressure based on my actual axle weights rather than just using maximum ratings or generic guidelines. What's the proper way to determine the right inflation pressure for these Fuel Max RSA tires given my specific load conditions? …more

Got quoted for a whole new valve stem system on my Class C Ford E-450, but shouldn't 4.25x2.25 oval dually stabilizers work for these 225/75R16 tires instead? The inner dually tires are nearly impossible to check air pressure without proper extenders.

What are the best sources for purchasing these specific oval-shaped valve stem extenders? Also wondering if there are alternative solutions that might work better for accessing the inner tire valves. …more

Monaco Knight 40 Fuel Economy: Real MPG Numbers When Towing a Car

Our 2012 Monaco Knight DFT 40 GOLD is sitting in the driveway right now with the Jeep hitched behind it, and I can practically see my wallet getting lighter just looking at this setup. We're looking at covering about 1000 miles over the course of the trip, and I'm trying to get realistic expectations for fuel costs and planning fuel stops accordingly.

I've heard wildly different numbers from other RV owners about what kind of fuel economy to expect when towing a vehicle behind a 40-foot diesel pusher like the Monaco Knight. Some people claim they get decent mileage, while others say it's absolutely terrible. I'd love to know what's actually realistic to expect in terms of MPG when towing, and if there are any driving techniques or speed considerations that can help maximize fuel economy on a long trip like this. …more

Fix Allegro Breeze Air Leveling System Module Problems

According to my troubleshooting notes, ever since I started diagnosing my 2013 Allegro Breeze 32BR's air ride system, I'm completely stuck on what's actually broken. Last month during a trip, one of the dump valves got stuck open and I lost all rear air suspension. HWH tech support told me to disconnect the control module and finish driving to my destination, which worked fine. When I got there, I plugged the module back in so I could level the coach properly. Everything seemed okay until we packed up to head home - now I can't get proper travel mode! The driver's side rear bag just won't inflate through the normal system, though if I manually open the inflate valve it fills right up. Is this still the same module problem HWH mentioned, or am I looking at multiple failures here? I'm trying to figure out if I need just the module or if there's something else going wrong too. …more
