Hi Everyone,

I was looking to get some feedback and recommendations for tires. I'm currently using the tires that came with my bike, I don't have any prior experience so I can't compare them to anything, they are Schwalbe Durano S. From reading some posts I was thinking about switching tires to the GrandPrix 4000s. For what its worth I in the NY, NJ area... Fort Lee area, 9W and Central Park. Mostly weekend rides with occasional small races (16miles).

I appreciate any input before I make the investment or just stay with what I have.

thanks!
