I'm curious - has anyone seen or heard of any manufacturing testing for ST tires? I have seen tires tests for LT, passenger, performance, etc, But what about ST tires? There are google reviews, that is not what I mean. What manufacturer actually tests ST tires and what standards do they have to meet?
ST tires, just like car and LT tires have federal motor vehicle standards they must meet. so the mfg is required to test to those requirements. Now for an ST tire, the test is not near as stringent as a passenger car tire.
Will a mfg publish results of the test? Highly unlikely. They just file them with the required federal agency.
In addition, tires like the goodyear endurance have a speed rating well above and ST tire (85mph IIRC) and there are federal standards and testing to meet those requirements.
Now as far as independent tire reviews, haven't seen any. And I've never seen an independent review of any tire where they actually test them to the load, speed rating, etc. that they must meet.
Occasionally independent tests will try to test the tire wear vs. tire wear rating, but that's about it.
