The tire folks have seen a market opportunity for TT tires with a higher speed rating. Carlisle's in the 70 mph range and now Goodyear in the 80 mph. range.
The tread and compound changes are also said to add to the tire performance.
My guess is the projected market for 500,000 TT and 5vers this years, plus the younger demographics moving into the RV market, help drive the decision.
US manufacturing makes for easier distribution and labor costs play less of a roll in the overall price of a lower volume, premium priced tire.
Now comes the real test, putting these tires on the road, in the hands of the consumer.
It sounds like a good move for the consumer. :)
