Bought my 2025 Winnebago spirit 26T 10 months ago. It had 1700 miles on it when I bought itI am now up to 3900mi. Since then I made several small trips within a hour or two from my home. As expected, I;ve had to make several field repairs myself, which I do not mind but at this point I am really questioning the Winnebago quality control process as this should have never made it off the production line!!!!!

First weekend out the hot water switch did not work stuck in the off position. Somehow that led to burning out the water pump second trip to dealer that was the first week of ownership. all seemed fine for the next couple of trips except for the radio screen/ backup cameras blanking in and out constantly. Back to the dealership found the wiring loom was not routed incorrectly pulling on a connector. In the fall of last year went out for a couple of days and realized NO HEAT from the heater. It would NOT turn on. Back to the dealer and found some Blue wire was never crimped. Not sure what that meant but was documented on the repair order. Then one night I heard a dripping noise coming from the shower. Went out and checked in the rear cargo bay and lots of water in it. I removed the shower faucet and sure enough drip drip drip. The fitting looked as if it was driven over by a forklift or something and the internal gasket chewed up not being able to make a seal. Luckily, I was able to get a fixable solution the next day from a local hardware store. Later I notice several fender well screws backed out over one of the front tires, easy fix.

Now yesterday on my way home from a two-hour trip I started to feel a vibration through the vehicle . My normal cruise speed is 65-68mph as this is the best fuel economy throughout my data collected. I flipped the dash screen to tires and rear was 74-78 psi on all and front 85psi looked normal, but I knew something was not right so I pulled off an exit to see if I could tell what was going on. Nothing visible so back on the road. Ten to fifteen minutes later it sounded like the rear end exploded. The tire shredded its tread . Crazy part is it still had air pressure. limped it 4 miles to the next exit at 10mph and got to where I could change the tire. Got the spare down and it had 4 psi in it. Impressed yet once again by WB QC. Luckily I do carry an onboard air pump easy fix. The tire still had 70psi so I stabbed it in the side wall to not have to worry about it blowing out.

Guess I needed to rant about my experiences so far but 4k miles on a new tire, COME ON !!

Wow that's crazy about the tire! I wonder if it was driven with low pressure before you bought it. Hopefully member @Tireman9 (Roger) who is a forensic tire engineer will see this. I would keep the damaged tire until the cause is determined and also have the others inspected. If you can't keep it consider taking lots of close up pics if you want Roger to asses it and possibly determine the cause of the failure.

What brand is that tire? I don't think you can fault Winnebago for that one. The tires come on the chassis from whoever supplies it. Our Concord came with Michelin. Checking the spare should be part of your normal maintenance routine.

Aaron :cool:
 
The fact that the spare was low may be a clue that the rig sat for a long time and was possibly driven on under-inflated tires before it was sold, which could have caused permanent damage.

If it were me I'd push them for a whole new set.
 
For tires, I think of that as a tire warrenty issue, not Winnebago. Do you have the tire info in the info case? I suspect it will not be a practical thing but would want to look at what is expected and what warrenty might/might not appply.
 
Tires are Hankook Dyna Pro HT 225/75/16 manuf date says Dot-BCXE HU H 09/24. Tires were excluded from any warranty. So, the question becomes should I trust the others and get a replacement or go ahead and replace all seven of them??

When the tire came apart it tore off the mud flap and bent the mudflap holder metal should that be warranty?? I can get the black tire marks off the side, tried that this morning.

I personally have never had a tire fail with such little milage and I have purchased MANY sets of tires to date. I had a trip planned to go to the Fl Keys next week, but lost confidence yesterday unless I replace all before the trip.

I know each manuf is responsible for their product. This happens to be the very First NEW vechicle I have ever owned personally, and I trust the Ford line, it has been reliable to me for over 35yrs.

Im questioning parts being used at the factory not being up to par.
 
Sounds like we are missing lots of details on the sale. Very unususal to me that I would buy a product that was assumed to be new but excluded from warrenty???
Nothing in the paperwork saying this is a salvage resale, etc.?
Sounds like possibly a good idea to have an attorney look at the paperwork for hidden tricks?
I have run across this sort of deal after hurricanes where there were sales lots flooded and the products were sold as salvage but buyer beware was included!
 
Bigb makes a good point as tires, even on cars/trucks, are under tire warrenty, not automotive warrenty!
But warrenties are often written to state proper care, like checking air is a critical part of the deal, so if the spare was not aired, the question comes up about air in the tires on the ground?
Lots of small points that seem "off" in small ways!
 
BigbAZ had wisdom in his post, Thank you!

I contacted a local Hankook tire rep about the tire, they told me to bring it in and said they will order one and have it replaced on Monday. Also told me to bring my rig up so they can inspect the other tires as well. Problem fixed with minimal cost of $57 for remount and balance plus inspection.


Sorry for ranting online, It was a BAD day.
 
Be aware that your motorhome is made up of many different parts from many different manufacturers. When a tire goes bad, as you’ve learned, that’s not Winnebago’s fault. Same goes for the A/C, the water pump and dozens of other components.

It’s easy to blame Winnebago but it’s not always their fault.

It will help to know more about your specific RV and tires.
Tire Size ?
Load Range?
Cold Inflation specified on the RV Certification label. Your 74-78 is your Hot psi not the cold psi
Scale reading for rach axle when you weighted the coach when fully loaded to your expected heaviest.
GAWR specified on your Certificated Label.
Not sure what you mean when you said you "stabbed" the tire
 
Not peculiar if they were overloaded and/or under-inflated. In my experience most tires that end up looking like these did not have enough inflation. Detailed inspection can many times find the physical evidence of this. No such thing as a "Fail-Proof" tire.
 
From here, it is my opinion that this whole trek is a combo of several things that are actually quite common. Things don't normally get to this crisis point but can be headed that way!
Looking at the things reported, we have a person who is frustrated, happens a lot, when things go wrong.
But we also have signs of not knowing lots of the odd things about an RV. That can mean mistakes are often made. Most of us also know that dealers are often way short of doing their jobs! As buyers we are often also guilty of not knowing what the dealer is expected to do when we pick up the RV!
So we often get an RV that has not had a good inspection. That is a combo of the dealer slacking and the buyer not spotting they are being shorted!
I've never been a dealer but my family has been involved in car sales and service, which has a few of the same ideas. Dealers get things that have been on the road or may not have been right at any time, so they are supposed to do a good inspection and never turn over a defective product! HAH! Anybody believe that is done on cars OR RV?
The RV is likely to set on a lot before shipped, sets on transport for X number of days and then on the dealer's lot! During that time things can go downhill and that is when the dealer has to do a pre-delivery inspection and make sure he is selling a good product! I don't think I have ever bought a car, boat, or RV where I felt the dealer did a good job! They tend to wait and see if they get away with shorting us??? Maybe the factory did not do it right, the dealer did not do their job and we were not sharp and experienced enough to know that we have to protect ourself in almost every business deal we make.
So likely the tires were driven underinflated and nobody along the line did what was needed to prevent it!

If you "stabbed" the tire to flatten it, then drove the MH for miles, now the other tire in a dual-tire wheel position is ruined too.
 
My understanding is he stabbed the tire after changing to the spare out of fear it might explode.
 
Would now be a good time to throw in my thinking on TPMS (tire pressure monitoring system) and how much value we can get by adding one?
I hate to spend money more than most, but a TPMS can save us lots of grief as well as money.
Before putting on another set of tires, I would definitely go for something to let me know BEFORE I ruin those new tires in some way! Tires lose air, brakes stick, lots of things happen, so I want to know about it BEFORE it costs me big time!
 
The rear tires had 74psi cold 80 hot, the front 80psi cold and 85 hot with running on the road after about 20 min when it blew apart. They were not under inflated or overloaded. I ran a CAT scale check and am at 13632. GCVW is 14500.

The spare had a hole in it and had to have it patched at the tire shop when they replaced the blowout.. It lost the 75psi I put in it within 36hrs. How a hole got there IDK?

I stabbed the sidewall with a kitchen knife blade to ensure it did NOT explode when I put it inside to get home.

Tires are Hankook Dynapro ht 225/75/16 front say 80psi cold and rear say 75psi cold but all are the same as far as I can tell just stamped differently.

Another, Why do the airbags loose 1/2 the pressure I put in overnight? I pump up to 60 and they drop to 30-40lbs overnight.

Does your coach have air-leveling? If not, there is no problem, just a small leak, which can be a leveling valve, dump valve, air dryer assy, or hidden check valve in the air plumbing
