The new bike has now done 500 miles but unlike cars, I've no idea how often the tyres should be changed? It's used on normal road conditions. The brow of the tyre is now smooth. Any ideas?

Thanks for all your advice guys; this has really been very helpful...and educational!

How do I know if my tyres need to be changed, and how long should I expect tyres to last?
