The pros say the TA's are about the worst. Old tech, poor traction.
Who are all these "pros" that say that? Pro's of what? Daily driving? Drag racing? Autocross? Highway driving? Endurance racing? Off-roading? Drifting? Names please, and more than just a few if it's not too much trouble.
A few inconvenient facts for you;
The T/A outperforms the Cooper Cobra (it's main competition) in nearly every objective testing category, including lateral grip and tread wear, to name two. I can find that independent tire test review again, if need be.
According to 1010tires.com, the T/A has an overall review rating of 4.9 on a scale of 5. It's interesting to note that a close examination of the lowest rated reviews reveals that a large number of respondents thought that a 1 rating was the highest rating possible. Read the comments sections.
The T/A has been and continues to be one of the most successful and longest running performance production tires, ever made.
It's great that you feel you have found a superior alternative to the T/A. Let us know how that works out, and how long they last. I must say I find your opinion entirely subjective, ill-informed, and in the case of your new tires, way too early to be conclusive.
It's a shame that there are so few performance tires available in some of the sizes many of us want. But that doesn't make one of the most popular, best selling and well regarded tires in history "about the worst". In point of fact, given the lack of comparable tires available, and their ratings, one could also conclude the T/A's are "about the best".
