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

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

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

Ford E350 Dually Wheel Center Hole Size Guide: Front vs Rear Differences Explained

According to my mechanic, my Ford E350 dually has mismatched wheel fitments, center holes that don't align properly, AND different sizing between front and rear wheels all at once. I have a 2001 Ford E350 Class C motorhome with dual rear wheels, and I desperately need to get a spare tire sorted out.

I found what I thought was the perfect rim - same bolt pattern as my existing wheels - but when I got home and really looked at it, the center hole is noticeably smaller than the ones currently on my RV. I've been assuming all six rims on a dually setup would be identical, but now I'm second-guessing everything.

Could it be that Ford actually uses different center hole sizes between the front wheels and rear dually wheels on the E350? I'm really hoping someone can clarify this because I need to know if I bought the wrong type of rim or if there's something else I'm missing here. …more

How to Fix Onan QD3200 Diesel Generator Fuel Leak Behind Air Filter

According to Murphy's Law, my Onan QD3200 generator is doing something bizarre — it's leaking diesel fuel from behind the air filter instead of where you'd normally expect fuel leaks. The fuel appears to be coming from somewhere behind the air filter box, and I'm worried about making things worse if I don't diagnose this properly. I've shut everything down for now because I'm nervous about safety issues.

I need to know the safest way to trace where this leak is actually coming from without creating a fire hazard or damaging anything. What are the most likely culprits in that area, and what's the proper procedure to identify the exact source? I want to make sure I approach this methodically rather than just poking around and potentially making the problem worse. …more

Locking Air Chuck Extensions for RV Dual Wheel Tires

Locking Air Chuck Extensions for RV Dual Wheel Tires

Halfway through trying to air up my RV's dual rear tires with my new Ryobi 18v ONE+ compressor, I realized I can't reach the valve stems properly. I need to add about 110 PSI, and the front tires are no problem. The inner rear? Also fine. But that outer rear tire with the valve stem pointing toward the center of the rig? That's where my dignity goes to die.

I'm out there doing some kind of yoga pose, contorting myself to hold the regular chuck on the valve stem while simultaneously trying to keep my balance and not drop the hose. I watched another RVer breeze through this same task with some kind of extension that actually LOCKED onto the valve stem - no circus act required!

What is this magical device called, and can I somehow adapt it to work with my portable compressor? I'm tired of looking like I'm trying out for Cirque du Soleil every time I need to add 10 PSI! …more

Dually Inner Tire Valve Stem Extenders: Where to Buy & Install Guide for RVs & Trucks

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

How to Release Stuck RV Emergency Brakes After Long Storage: Rescue Your 1990 Pinnacle

Nobody warned me that parking my 1990 Pinnacle 30' Class A with grabbing brakes 24 years ago would leave the emergency brakes completely seized. Now it's sunk into the ground and I can't even get underneath to try disconnecting anything.

I'm afraid to force anything or use the wrong approach - could I make the brake problem worse? What's typically wrong after this many years of sitting, and is there any safe way to try releasing stuck emergency brakes myself? I'm concerned about what other brake components might need attention before this RV could ever be roadworthy again. …more

Class A Motorhome Wheel Balance Services in Columbus Ohio - Fix RV Steering Shimmy

Despite getting my tools ready and being determined to tackle this steering shimmy hitting my 1997 Class A motorhome at 55 mph — where should I start? Based on my troubleshooting, this appears to be a wheel balance issue, though I suspect there could also be tire wear patterns or front end component problems contributing to the vibration.

I need to locate commercial truck tire facilities in the Columbus, Ohio area that can properly handle motorhome wheel balancing services. Standard automotive shops don't have the equipment for larger RV wheels, so I'm specifically looking for commercial-grade tire service centers that can diagnose whether this is purely a balance issue or if there are additional front end problems requiring attention. …more

2005 Rusty Spare Rim on 2001 E350 RV: Safety Guide and Inspection Tips

Before I do anything else with my 2001 E350 RV, this rusty spare rim is eating through my confidence way faster than it should. The rim currently holds air pressure with an old 2005 tire mounted, indicating the bead seat may still be functional. However, I'm concerned about the safety implications of using a rim with visible rust damage on a 13,000-pound RV.

Specifically, I need to determine: Is surface rust on the outer rim area a structural concern or merely cosmetic? What's the proper inspection protocol when having a new tire mounted? The rim appears to seal properly at the bead, but I want to ensure this spare is roadworthy before installation. …more
