I am looking for tire suggestions. I will be riding paved roads, Burley tamburello is the bike with my 9 year old son on the back. Total team weight of approx. 250 to 260 lbs. I am not into flat tires. Currently the bike has 700x28c tires. I was looking at the Continental Gatorskins. I will be doing a couple of multi-day tours pulling a Bob Yak trailer.
