I first noticed it on Tuesday but attributed it to the wet roadways. (It rained cats and dogs on the way home.) But then I felt the same thing yesterday at lunch and then again this morning with dry pavement.
Its a subtle squirlieness with my rear tire on turns. Nothing that's jerky or abrupt but a slight shift in position that caused my to say, "Did I just slide a little?"
The air pressure is about 1 pound more than recommended so that might be the issue. The side tread seems to be plenty deep. But the rear tire just doesn't seem to "stick it" like it used to do. The bike has 8,000 miles on it and these are the original tires. I had hoped to get at least another 2,000 miles out these but that may not be the case.
Any ideas or suggestions or preferences about tires?
