Hello folks.

Ive had my Trek 7.2FX for a a few months now.

I was cleaning it with a rag yesterday, and while doing my rims i noticed the tread on my back tire had a green spot. I guess this is some type of warning build in saying hey....change me!

So im looking at my options for new tires.

I enjoy going fast, the tires i have are great, but something in me wants a thinner tire. I've googled and it seems like the smallest i can go is 700x28. So, my questions.

1.What are some good 700x28 tires that will let me enjoy the speed i love?
2.Do said tires have puncture resistance?
3.Should i get something that doesnt have puncture resistance and get Tuffy Tireliner ?

Read about Specialized Armadillo and Cont. Gatorskins, and the reviews for both seems almost the same, both are heavy, but does what it says.

Im still new to biking, so i don't know what to look for in tire specs.

Oh, and i DONT want to get new rims, not for now atleast, just want a smaller tire if my rim permits it


Thanks for any and all help
