In the absence of anything more taxing, can someone please answer these questions for me?
1. How do I measure the tread on my tyres (using some simple tool that I might have access to) and how much tread should there be for it to be road legal?
2. Is it normal to be losing something like 4 or 5 lbs pressure from the front tyre every time I ride the bike? i.e. I put it away after a ride and the next time out I check the pressures and they've gone down about that amount on average.
