15" tire replacement with Carlisles

[nwhouston]

Some may have noticed my parts drama with changing the brakes and hub/ bearings on our '07 3124. As part of that work scope I pulled the tires and found pretty significant blemishes on both. These were a knock-off brand installed by The Car Show in 2013 (DOT code was 2213) when we bought the trailer as the second owners.

One tire had a failure just off the tread surface at the top of the sidewall. About 8 or 9 inches of cave-in was starting to show. The other was developing a delam under the tread layer, evidenced by a noticeable bump. So I went to Discount Tire (my normal shop) with both tires and the spare. The rep confirmed what I was seeing in the two tires were delam issues. The tires had about 42 months service and 12k miles. Always stored in a closed garage, so little sun exposure.

We also looked at the spare I had carried in to the shop. The original Goodyear Marathon from the factory! DOT code 2306! An 11 year old spare. Never had seen a drop of sun shine. There were notable indention in the sidewall on the side of the tire that presses onto the spare tire frame. So that got replaced as well.

Used steel valve stems as my TPMS vendor recommends them. Normally an upcharge but the lads gave me three for free (after I gave them $476, so free is a relative term).

Many recommend and buy the Maxxis tire, which Discount Tire (at least my shop here in Houston) can special order. But I needed something ready to put on when my brake / hub job is done at the end of the week.

Comments welcome but mostly just posting to highlight the spare tire aging risk.

What tires did you wind up getting?

Sorry, should have been more clear. Carlisle sidewall label: ST225/75R15. Nominally a radial tire, though with trailer tires you probably find a low pass mark for what that really means. I did go with E load range tires, so 10 ply, but only inflated to 65 psi as 1) that is all the trailer weight demands, 2) that is what the rim is rated for (weight, not pressure) and 3) any more than that and I have a lot of loose screws and broken eggs inside.

Hope above helps. Larry

I had bad luck with Carlisle tires. I had 3 blowouts on one trip with two year old Carlisle tires. They sent me new ones after I had already purchased 4 new tires on my trip. I have the Carlisle tires away. I wouldn't run them on my wheelbarrow. As luck would have it , my ntm TrailManor came with Carlisle tires that are three years old. I am replacing with Maxxis tires from Amazon. There are several horror stories on the web about Carlisle tires.

To be fair , this happened to me 14 years ago. Hopefully now they are manufacturing better tires.

14 years ago, I bet they were bias ply not radial. Bias ply were alway a hit or miss.
