there really isn't a supply issue .... the reason that there have been comments is because all of the tire manufacturers are just no coming out of winter tire season .... we are currently recieving the first shipments of 2003 summer tires ..... so don't worry about supply issues for tires they will be readily available .....

as far as the Dunlop 9k ...it's a pretty decent tire but, it does issues with tracking on uneven roads and does not have the performance of some of it's competition ..... it does have low road noise and good ride quality though
