I've been losing air slowly in one of the tires on my 2004 GP GTP for a long time now. I'm sick of having to put air in it every 3-4 weeks (especially on days like today when it was cold & crappy out). This is after having purchased new tires last year too, so it seems to be an issue with that particular wheel. Any suggestions for where to look for a replacement? It's the 17" alloy (10 spoke I think???) wheel.
Thanks.
