No...I don't mean stand back and see that they are black things with tread on them!!.. Have a good close look....It's not enough to dismiss the tyre as ok, just because it has good pressure and reasonable tread...what is the general shape of the tyre...? Bikes respond and react extrememly differently to car tyres....every little thing will have a marked effect on the ride, grip, and general control of your bike. If your tyre has a few thousand K's on it or more it has experienced some "wear"...so where is that wear? Look down at your tyre and observe the shape...is it evenly worn or more on the left or right sides...is it starting to show signs of a flat spot in the centre-line...how pronounced is it? Is the rubber "tearing"?...are the tread "edges scuffed? Why!?...because now that the dryer weather is here and you venture out onto the open roads more, you may find your bike feels a little unsettled...wants to track along grooves in the road...feels a bit wobbly through corners, or suddenly pitches over on corner entry and does'nt want to stay down on corner exit... All of these things could easily be caused by the way your tyre has worn from the style of the riding you've been doing over winter, or commuting etc. Don't be a rider who just blunders along without knowing wtf is going on. Tyres have a lot to say, and, you should be listening to them. Go see what your tyres have to say to you, now. :grin: Report back here if you don't understand their language.. John.
