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.)

Not sure but am wondering how running over something in the road and having the tread and upper sidewall cut & punctured demonstrate the tire is "junk"?

Can anyone identify a standard tire that is puncture-proof?

Just because the vehicle is a truck doesn't mean it can be driven like a real HD vehicle.

Passenger tires are kind of a strong indication for the intended use for that vehicle.

If you consider that I should replace any of them now what specs should I be looking for?

TT Tires:
Castle Rock ST
ST205/75R15
Tread: 2 nylon plies & 2 steel plies
Sidewall: 2 nylon plies
50 psi
Made in China

Truck Tires:
Goodyear Wrangler SR-A
P265/65R18
51 psi
Made in Canada
Wondering about the Silverado. Did you include the HD towing package that GM offers on its trucks? What is the rated towing weight for your specific vehicle?

Some are advocating upgrading the tires to higher Load Range. While the tires could be the lowest rated component (springs, axle, brakes, shocks, sway bar frame etc) just changing the tires to real truck tires not XL passenger tires does not make the Silverado a HD truck which IMO is what people should use for towing.

When every week, someone is blowing out one of these this P rated tires on their truck, I say it is a problem. Yes, the tires are rated at 2500lbs each. But, they are so thin and light, the littlest thing pops them. I have 44PSI in mine. I had to go over a 3 inch timber at the edge of my yard, where my trailer is parked. I stopped with the left front tire on the corner, and I swear, it was down to almost the rim. These GoodYears on the EcoD forums are like the ChinaBombs on these forums. And when people have multiple failures in 10,000 miles...

People ask for / demand better fuel economy one thing that can deliver an improvement are tires designed for smooth highway speed i.e. lighter weight tires.

Thick sidewall are bad for fuel economy, at least based on the Physics in this Universe.

If a 3" timber compressed your tire almost to the rim you were only riding on one shoulder of the tire and not the entire tread.

The tire in the picture posted shows clear evidence of some sharp object cutting the tread and upper sidewall before it got to the sidewall.

If you want truck tire durability then I suggest truck tires not passenger tires. Also be willing to accept lower mpg. This is your choice. The problem is that GM has to be competitive in the market and meed fuel economy requirements on their passenger based vehicles so their only option is to put passenger tires on their vehicles designed basically for light duty passenger service.

I have the same truck tires. While the max pressure is 51 psi I understand it's recommended that they be ran at the door sticker pressure of 35 psi cold.

Dude, I have 5 Wheels and Tires on order. Replacing my P275/60R20s with LT 275/65R18 Michelin LTX M/S2. I got 16K on the truck and with my Big road trips coming up, not trusting these tires.

I would look closely at the truck gross and load capacity as well as the total hitch weight that you really have. Those are fairly light truck tires if you were reading max cold infestation pressure.

The trailer, probably junk China bombs. But obviously FR thinks they are enough tire. Probably 3500 lb axles so again, I would look at the load rating of the tires an get an actual weight on that full rig before I went too far at highway speeds.

If weight limits are even close to max tire rating, I would be looking at heavier tires. Especially for the trailer. Max 50lbs usually means Lr C,. 65 psi is D and 80 psi would mean E.

I would feel safer, at least upgrading tt tires to D. 15 in 215s can be found in D I think and Es if they will fit can be found in 225s IF those will fit. Too much tire is usually better than the other way around. D or E still keep pretty close to max cold inflation. That said, our new TH came with just D and I will try them for awhile since we carry no toys and should be light of max rated weight. Happy towing.

RE "Highway Speeds" Don't forget that ST type tires are rated 65 MAX, Not avg or occasionally faster. Speed rating on tires is like engine redline. While you may be able to run faster you will pay with shorter life.

Even if the ST are new design with a Speed Symbol you need to remember that the major tire companies place a 75 mph max speed limit when in RV application.

Speed Symbol test comes from regular passenger tires and a tire only is required to run at the max speed for 30 minutes on a smooth drum with no potholes or road trash.
The tire is considered scrap after completing the test
