TOWMAX failure
Here is a pic of the spare tire on my single axle utility trailer with 225 75 15 Towmax 6 ply tires. The tire has never been on the ground.
The thread has delaminated, but not unexpected. It is about 5 years old and is always outside exposed to weather.
I'm replacing with Carlisle HD from a nearby little shop that beat Discount Tire on price pretty good. Also will order a spare tire cover and covers for the tires that are in service.

gearhead,
When they get that tire off the wheel, take a look at the inside. I'm betting you'll find that the tread delaminated from the carcass, just like mine did. Here's what the inside of mine looked like. I'd be very curious about the inside of yours (if you can get a few pictures)...

When I was at the tire shop the DW called and told me contractors were wanting to get in the backyard to look at an electrical switchbox they are going to replace. She said I need to "GET HOME and deal with these guys"!! So I high tailed it home as soon as they mounted the tires. No big deal with that.
I bet the tire will be there tomorrow. It's just around the corner (small town, everything is just around the corner), I might go get it.

Thank you, that reminds me to change my spare too! Any idea if the steel spare wheel has the same psi capacity as the main wheels? The main wheels on my Raptor are stamped 110psi, not so sure about the spare wheel.

I've been led to believe that if that wheel has a bolt in solid steel valve stem, it is rated for 110psig. My spare has the bolt in stem though the wheels on the 5er are rated 80 psig

Having a cover over the spare is likely a good idea. On the AF forum several years ago guys where posting photos of their spares with covers on and blow up tires. So, it may help but, can still happen. Not sure if all were in the southern hotter states or not. I seem to recall they were.

It's been raining for 2 days so I'm not digging through the pile of used tires in the rain. I assumed it delaminated by the looks of it.
The Carlisle HD is a good looking tire. I've got 6-12 months before I replace the 5th's tires. Completely happy with the Maxxis', but Carlisle and Sailun are on the "short list".

Most steel wheels are rated much higher than aluminum. For example, the Sendel S62 steel 8 lug wheel is rated for 145 psi.

I bought a 2016 Cougar 5er last December. After returning from FL in March I started researching replacements for the Trailer King 235/80/16 LR E. Sailun would be #1 if not for the 110# psi requirement. So I was down to Maxxis and Carlisle. Last week I had a few minutes with an independent tire engineer (who knew there was such a thing) in Akron OH. Gave him all the 5er info and he suggested the Carlisle. Although the LR E will give plenty of cushion for me, there is an F rated Carlisle that requires 95# PSI. Overkill for me but may work for others, if their wheels will support the pressure.

My stock Sendel wheels are rated at 94 PSI.

Saw photos online and are similar. Specs are close ~ I'm a 2016 and only 300# heavier but the same tires are standard. If I can determine mine are the same I'll order the F rated as they are only $7 more. Thanks!!!

The Sendel T03 is the most common wheel used on our trailers. Here's a link to their website that should help you determine the wheel you have as well as the specs. As a side note, I spoke to the rep from Sendel and he recommends the T08 or T11 for our heavier trailers (my GVWR is 15,500). I found them on Amazon for under $80 each.

Just be careful with TO3 wheels. Sendel and Tredit look exactly alike. So much so that I wonder if they are not the same wheel.
But, the capacity specs are different according the manufacturer's websites.

All of the aluminum wheels used on Keystone products are marked on the back of the spokes with weight capacity and part number. It "should be easy" to identify the weight capacity (not the PSI rating) of any wheel that's OEM from Keystone. Here's a picture of the back of the spokes on my wheels.

Towmax Junk?
I think so. I have 10 ply 15" Carlisle the tires are over 3 years old. But I drive at 65 mph speed and china bombs do make a poor mix ....Bushman
