Nothing too revolutionary here. You just don't notice the gradual degradation of performance of your tires until you swap the old ones for new ones - I got 8K from my PR2s, 8K from the PR3s, and just put a pair of PR2s on. IN both instances the front tire was totally toasted while the back was in better shape, but for convenience I swapped both. Driving on a new pair of tires is like riding on glass. Also the effort to initiate a turn is so different versus tires with squared off sides and top. .... and it's sunny and warm out
