Review of Goodyear Tires and Wheels 724857519

Speaker 1: Today, we're going to take a look at the Goodyear Endurance ST225/75R15 Radial Trailer Tire in a load range E. Now this was a radial trailer tire, which is great for highway use. It is a special trailer tire design, so it couples a strength of a bias tire with the durability and stability of a radial tire. It is created specifically for trailers, it's not intended for use on any other vehicles.On this Goodyear tire, they do use an optimized tread depth and on each side or shoulder here they use decoupling grooves to help the tire remain cool while towing heavy loads. They do use a specialized inner liner on it to minimize air loss in trailer applications, because of the use of 100% halobutyl rubber. Does use Durawall technology, which helps resist sidewall cuts and punctures.

And there's even a little raised area here that's a scuff guard, helps provide sidewall protection.Now this is a polyester radial tire with two steel belts and a nylon overlay. Gives you improved durability and carrying capacity. This tire is compatible with TPMS, the tire pressure monitoring systems. It does meet the DOT, Department of Transportation specification and this tire sort of unique because this is the only trailer tire being made in the USA now, most all the tires are made overseas.A few specs on this, this tire is designed to fit on a wheel width of 15" by 6" wide, 15" by 6-1/2" wide, and 15" by 7" wide wheels. The tire size which is stamped on the sidewall right here, ST for special trailer, 225/75R15, the R means it's a radial design tire.

Section width on this size 8.8". Overall diameter from the bottom to the very top when it's inflated is 28.3. This tire is a load range E, which means it's a 10 ply rated tire. Has a maximum load capacity of 2,830 pounds at 80 PSI.And the last thing I do want to mention is most all the new trailer tires are coming through with a speed rating on them now. And a speed rating they designate by a letter designation and where that is on the tire, if you'll go right down on around the bead here, you'll see the tire size again repeated.

Right after it, you'll see two numbers which are the load index and the letter N. Speed rating N on this tire means it's an 87 mile per hour speed rating. But that should do it for the review on the Goodyear Endurance ST225/75R15 Radial Trailer Tire, in a load range E.

I have 6 of the ST225/75R15 on my race car trailer and I have always run max PSI of the tire. I was just introduced to the PSI vs WT capacity chart of the Endurance of which goes against my experience in towing for over 30 years. What is the reason for making this possible Thank you 99289

Great question! That's actually something new to us as well. Basically what happened was that Goodyear entered the trailer tire industry and did more testing to their tires and readily released that info. All of the regular trailer tire brand names didn't do as much testing or releasing that info and so we have been seeing some of those companies now releasing the same types of charts as well as pushing the speed rating on the tires as well. 73823
