I've owned a Trek 3500 bike (shown below) for 2.5 years now and I like it very much.
My bike has the same specs as under the link. It has the XL frame size and 26" wheels with Bontrager AT-550 36-hole rims. I've started looking into changing the Bontrager tires to slick road tires though as I've begun to ride more for exercise and not just recreational. 95% of my riding is on paved roads/trails. The problem is I have no idea what tires can work on my bike for me. I'm considering the high pressure Kenda K193 tires. Can anyone advise? I'm looking for the best tires I can get for around $35 each. Is it even possible to replace the 2" tires with 1.5" without needing to buy new rims and everything?
I'm riding ~35 miles on weekends and let's just say I'm right now a heavier guy (~300 lbs). I've ridden on the same tires almost daily since I first bought it, so I feel it's about time to change them anyway.
