HRZ - I thought the Test was a little bogus in that it didn't include some quite popular ST Tires, Angel GT, Avon Storm XD etc
In addition, they collected a **** pot full of data, 15 things as I recall the guy saying.
It would sure be nice to have a look at the Matrix of all the tires and all the ratings instead of his subjective take my word for it the Metzlers are best!
In addition, based upon the many reviews on here and on other sites praising the PR4's both for grip, wet and dry, mileage etc......I further suspect that this is a bought and paid for review.
