Castle Rock tires

[Reeac]

I have 2016 Castle Rock tires st205/r75 14 that came with the rig. I’ve put 4000 miles on them with no problems, I check and service them every time before moving the trailer. Anyone out there have any have any bad experiences with the newer Castle Rocks I know the older ones had blow out issues. Considering upgrading to the Goodyear Endurance tires. They can get them today for $100 ea plus a $60 rebate from Goodyear.

My trailer is a 2018 bought fall of '17. The tires were Castle rocks and I didn't like the history or the look of the contact patch. The contact patch is recessed in the center even at max psi.

I swapped to the Goodyear Endurance (up from load 'D' to 'E') and couldn't be happier about the switch. I was shocked that I could tell a difference within a few miles at highway speeds...less side flexing and up/down motion. I just put 2800 miles on them in high temps and at speeds above 70 miles an hour. The increased speed rating from 75 to 87 combined with the increase weight rating was good for my conscience.

My friend at work and I had a discussion about these tires because he had them on his new trailer. He told me after a pull that he could feel a temp difference between the center of the tire and the outside. It would have been nice if he had a temp gun with him but anyway he swapped for the Endurance before using the trailer again.

I'm glad I switched.

There are hundreds of posts here about Castle Rock tires and thousands more about switching to Goodyear Endurance.

A search will bring up days of reading.

Dump them!!!!!!!!! They are an explosion just waiting to happen!

We recently upgraded TT and have Castle Rocks. I checked the load ratings and they just barely meet the TT GVWR. I was also concerned about the 2 ply sidewalls.

Sooooooo I am replacing them next week with Goodyear Endurance. Now I'll have a better tire with a safety margin in the weight ratings.

BTW, anybody interested in slightly used Castle Rocks 205/75/14 with 9/32 tread remaining?

I haven't had any problems with our Castle Rock tires but I also don't go over the rated speed rating of maximum 65mph. I usually tow around 62-63 mph and have never had a problem with any trailer tire in 50 years of towing.

A done deal. Purchased the tires and will get them installed next week.

Good for you...I know I felt and slept better about switching.
Safe travels.

My castlerocks are on 14 inch Lynx rims which are rated at 50 psi, so if you replace with 65 lb 2015 tires, you will need to upgrade rims. I am not an expert but this was what I found in my research.

Just got back from a 350 mile round trip and couldn’t be happier with the tires. I instantly felt more stability. I do not feel the trailer react to the 18 wheelers as much as before and when the winds got up to 18mph I definitely felt more stable

Just got back from a 2,000 trip in two weeks. My Arctic Wolf 315TBH8 came with Castle Rock E rated tires(speed rated to 75) and I haven't had any trouble with them at all. I tow between 65-70 on the highway except when the big hills get the best of my little baby 5.4.

Funny how that works. Stay within the design parameters and no issues.

Same here as to towing speed and I run a full 1,000# less than the max rating for my 4 tires.

I may change to a different brand of tires in another year or two but in the meanwhile I'll just cruise along and get some miles out of the original factory tires.

Yep, I did that too. Got about 8000 miles and 16 months out of the original Castle Rocks. Always within specs, pressures and speed... then three of them failed.

They WILL fail. Funny how that works.

So.... The consensus seems to be if you purchase an RV, you better figure on another $500 to $700 bucks on new tires and possibly new rims??

We have castle rocks on our 2017. They came with a 2 year warranty plus nitro if that is any better. You call them and they send someone to you where ever you are. We had 1 tire that picked up a nail. They came to us to fix

Just got back from a 3500 mile trip from Indiana to Badlands, Yellowstone, and Grand Tetons. Flagstaff Superlite with 15inch Castle Rocks. No problems at all, took it to Florida last year with no issues. That being said when I do replace them it will probably be with GY's

I thought my 14 inch 205 castlerocks were only rated C, with 50 psi. But find they are D rated, and 65 psi, and have 75 mph rating. Have around 1500 miles on them after one year, and so far wear is very even and when I check the temp....with my hand during a trip, they are not hot, only warm in hot summer weather. Bought a tire pressure/temperature monitoring system and assume that tire would heat up ….and would get a warning on the system, before a blow out. Tires were nitrogen filled, and I will use regular air to keep them at 65 psi.

I have had 2 CR ST 226 tires blow out in the last two months. I also had to replace one a year ago that had a crack in the side wall. I check tire pressure each day before I start a trip. I've never weighed my trailer loaded, but based on the manufactures listed dry weight and my estimate of what I have on-board, I don't believe I've overloaded the tires. I also drain all my tanks before each drive since I know that water at 8lbs/gal can add up in a hurry. Both blowouts have been at the same tire position which may indicate an additional issue that I am having looked at. The first blowout caused about $2300 in damage and I'm assuming that this one will be at least that much. (as an aside, the lug nuts on this trailer are junk!)

You do know this is a four year old post don't you?


How old are your tires. depending on how the RV is used and stored and if covered or not about 5 years is MAX age on tires, the collateral damage you suffered far outweighs longevity
