Are these tires OK?

Just bought a new truck (Silverado 1500) and new TT (Wildwood 27RKSS).

Below are the specs for the tires currently on each.

Are either of these crapola tires or are they ok (i.e. safe)?
If you consider that I should replace any of them now what specs should I be looking for?

TT Tires:
Castle Rock ST
Tread: 2 nylon plies & 2 steel plies
Sidewall: 2 nylon plies
50 psi
Made in China

Truck Tires:
Goodyear Wrangler SR-A
51 psi
Made in Canada

My 2 cents-

Change the TT tires to load range d and sell the old ones on Craig's list. Don't forget the spare.

I would continue to use the tires on your truck at max sidewall pressure while towing until they are worn and due for replacement UNLESS you have a sway issue-then upgrade to load range d's or e's.

All tires sold for use on public highways must be "certified" by the tire company to meet published regulations. The RV company is responsible for advising of the inflation needed to carry the load as shown on the certification label.
The label is located on outside at the front end of the driver side of the trailer.

While "Made in China" is correct it might be more meaningful to know which tire plant made the tires as I do not know of a "Castle Rock" tire company so this is just a name molded on the tire. To learn the tire plant and even more importantly the 'BORN ON" date we need the full DOT serial molded on the sidewall of every tire.

Another item you can use to judge the quality of your tires is to check for the written tire warranty. Is it good for 30 days, one year? or did it expire the moment you drove off the dealer lot?

You might ask the RV dealer for the location of the nearest dealer selling and servicing Castle Rock tires

Go to any of the truck forums and you'll learn that the Goodyear SRA tires are pure JUNK. The sidewalls are paper thin (well, not quite but you get the idea). Even without a trailer hooked up they let your truck do a lot of swaying, especially when a big truck or a box truck passes. I even noticed movement when getting passed by large sedans at 75+ MPH. At least you can get a new set for about $500. If you're lucky they might last 35,000 miles.

Go get a quality set of E-loads.
At some point during every day you suddenly realize nothing else productive is going to happen the rest of that day. For me, it usually occurs around 9 am.

You didnt exactly specify, but I assume your new truck and trailer is actually "new"...not just new to you. The below post assumes a brand new truck and trailer.

While there are certainly far better tires out there for both your TT and TV, they will most likely give you at least several years of service before needing to be replaced. At that time I would upgrade both to something better. Replacing them now and selling them as used is also a good idea (it's what I did, but is not as cheap).

What you should buy right away before any lengthy towing is a TPMS (Tire Pressure Monitor System) for the trailer. In my opinion, this is far more important than upgraded tires and should even be used with upgraded tires. Armed with a TPMS, you will be instantly notified of a tire failure (in fact most often BEFORE failure) and should be able to react accordingly before doing any damage to your trailer. In case your not aware, TT tire blowouts can cause thousands of dollars in damage to a TT before you ever realize the tire failed. A good TPMS will run you about $200-$250 for 4 tires.

TPMS recommendation

Yes, both are truly new. Not just new to me.

Thanks for the tip on TPMS. I was also wondering about those.

Can you make a recommendation? Are these easily user installed?

Never heard of the Trailer Tire. I have "china bombs" on my trailer, but I also have like 2000 to 2500 pounds of margin between my axle weights and what my tires are rated for. I would be worried if my margin was close.

The GoodYear SR-A are good for fuel economy and they are cheap to put on. Other than that, they are pretty worthless. The EcoDiesel community is constantly reporting blowouts with them. I currently have 5 wheels and tires for my truck to replace the SRAs. (Note: Not my tire. This is a fellow EcoD memeber who ran over a dead animal.)
