Might seem obvious, but have you checked your pressures? Were the tyres Ok before you laid the bike up? If so, they might just need a good hard ride to bring them back into condition but that said, I never saw the sense in keeping a pair of tyres you don't like. If you want a change, consider T30's. IMHO the best tyre I have ever put on a bike.
