One thing we can all be sure about tires, is you'll find as many reviews as opinions
Depending on the magazine, the winner often isn't the same. Some LOVE the PR2s, some have been disappointed by uneven wear. I went through probably 6-7 sets of PR2s, and was never disappointed once. I know some are in love with the BTs...and some aren't.
With that said, the best move you can make is replace the stock tires with just about anything else, you'll se an improvement in all departments
