Tire Question-Help Please?
Just started riding my new(vintage)Trek 520, built in 1985... very sweet and smooth ride.
However I noticed some rot on my back tire and some wear on my front and was thinking I would treat the Ol' Guy(the bike not me!)to some new rubbers.
Speed isn't important(I am slower on it than a turtle)nor is fashion(she's vintage after all)BUT I do want something dependable, long lasting and beefy.
I'm a heavy guy-Clydsdale-and wanted to know how I can get the most beefyness that's out there in relation to tires. They are 700c's and I guess I am curious about the differences between something like a 700x32 and a 700x40... would the 40 be more stable for a bigger guy like me? And also, is there any connection between my size and a tires Max. PSI... for instance I found a 700x37 tire that can inflate to 90 PSI and another tire, 700x40, that only has a 50 max PSI... what gives?
Last question... for any particular tire size what size tube do you need-the exact same size or one that falls in that size variance ex. 700x32-40 versus 700x32?
Oh, almost forgot to mention... currently my Trek has Presta valves... when I buy some new tires and tubes, any advantages/disadvantages to Presta versus Shrader? Either is fine by me as my pump can accept both but I was curious as to their differences.
Sorry for any moronic questions here... but I'm trying to learn!
