Ever trailer I have owned, that I remember I have upped the load range or old school ply tires just to have more extra reserve in wt and maybe a longer lasting tire. This trailer came with "D" tires at 65psi. If your 14 wheels can accept a E rated tire, if it were me that is what I would go for in any brand you buy.
Edit: check the wheel before buying tires for higher psi.
I went up one range. It came with "C" tires. I don't think I would want to up it two ranges.

I would not go up another load range again either. 1 makes sense, more may not be possible.

My Bullet's OEM tire size was the same: ST205/75/14 LR-C. These supported 1760 lbs of load at 50 PSI. These ran on 3500 lb, 5 lug axles. As I wanted to increase to a LR-E tire, I was unable as the OEM wheels were max'd at 1900 lbs. It was next to impossible to even find a replacement 5 lug (5x4.5" lug pattern) wheel to support an LR-E tire in size ST225/75/15. Ended up buying Hispec wheels off Recstuff.com that were rated for 2540 lbs of load. Mounted LRE St225/75/15 Carlisle tires to them and had my cold air inflations pressures capped at 65 PSI.

With the new wheel and tire combo, the trailer tracked and performed better at highway speeds than the smaller 14" LRC Trailer Kings. Some say the trailer may get "beat up" more with a firmer, higher PSI tire. I found the opposite true as cabinet and storage space items would stay now stay put and shift less during travels. The trailer just bounced around LESS.

I have since upgraded to 5200# 6 lug axles and 6 pack leaf springs (mono leafs were OEM). The tires and wheels are now perfectly matched at 2830# (LR-E). Was definitely worth the money to have the extra reserve in tires, springs, tires, and wheels.

Discount Tire didn't think that the cracking is enough of an issue. They said to bring the trailer by, but they probably couldn't do anything. If it was bad enough they might give me some credit.

Looks like stress cracks at top of body ply turn-up. Not unusual. Keep an eye on the cracks for now. Is the picture of the worst?
How long do you plan on keeping the tires?
What is the DOT date code?
I assume you have not been using tire covers as I recommend in my RV Tire Safety blog. Covers would decrease the tendency to crack.

I think it is just "cosmetic" for now as long as the cracks do not grow.

You are not running 65 psi in your passenger car tires. This is a big difference.

Carlisle will probably cover that cracking damage. However, the warranty is only good two tears out from time of purchase.

It could actually be the 303 protectant causing your issues. It could contain certain chemical compounds that draw the plasticity out of the rubber compounds of the tire. Since it is a similar product to Armor All, I wouldn’t be surprised if it did. What they don’t tell you about these products, is that they actually can accelerate the dry-rot process. Sure, the products are great for keeping tires looking good.. ie Nice and Shiney, but in direct, constant sunlight they are not good for rubber compounds. They destroy the plasticisers in the rubber compounds in the sidewall of the tire. I used to use tire protectant products on my trailer tires for years to “protect them”. They all ended up with premature cracking on the sidewalls. I stopped using these things and just keep the tires clean and covered on the trailer and now I am not seeing the same effects. I’m not saying not to use a protectant, but I wouldn’t rely on it as a miracle product in a bottle to stop the UV rays from reaching the tire. Covering them is the key. Just my two cents.

Yes, the pictures are the worst. I was hoping to get 4 years out of the tires. I need to check the DOT date code. I remember checking right after they were put on and it was only weeks before.

Spray protectant. To my knowledge there is no after-market spray shine stuff recommended by any tire mfg.


Also I have never seen a controlled long term comparison test run by a tire company.


RE DOT code EVERYONE should have the full DOT serial written down and kept with important information as if there is a tire recall the DOT serial is what determines if you would get new free tires or not. If you get a puncture and destroy the tire and discover later there was a recall, without some proof you could not make a claim to get a new tire.

The dates on the tires are 2017,2117, 2117, 2217. Got some more pictures. The attached is probably the worst.

Have you sent those photos to Carlisle? If Discount tire told you to bring the trailer by so they could check the tires, have you done that yet?

If there is a 24 month warranty time frame from Carlisle and the tires are dated "mid year, 2017" then you're likely fast approaching the warranty expiration. I'd suggest finding the sales receipt and sending a copy of it and the photos to Carlisle before the 24 months is up.....

A precedent for the highway man.

https://www.law.cornell.edu/cfr/text/49/570.62

Notice early on they describe the tire size as "size designation". A ST205/75R15 is smaller than the ST215/75R15, thus a mismatch is size designation.

A ST205/75R15 LRC is identical in size when compared with another having LRD capability. They both provide identical load capacities when inflated to 50 PSI. Therefore, they are not a deviation from the OE tires in size.

I did send in a warranty request to Carlisle (with pictures of the dates and cracks). I'm just past the 24 months (install date), so I doubt they will do anything.
