As I understand it the TPI for tires is the threads per inch. Is one better than another? Does it depend on useage? What is a good all around value?
Mike

Generally, the higher the thread count, the easier it rolls................

Value is very subjective ----durability, resistance to flats, traction, dollars, all enter into it.

All other variables being equal, higher TPI's are generally better. Less rolling resistance, thinner, lighter, more flexible.

When comparing different tires, all other variables aren't always equal, though.

it makes a difference
but a very minor difference
unless you are an elite athlete
and all other variables have been optimized

i find that other tire attributes are more important
like weight
width
pressure
and presence or lack of flat protection in the tire

and
ironically
having the lightest
narrowest
highest inflating
tires
is seldom the ideal choice for most riders

Also understand that as a marketing device claims of TPI might not be saying the same thing. If your tire has two plys of 60 TPI each it can be said that the tire has a 120 TPI casing. Andy.

Thanks for the input. The answer is now as clear as the decision of what color bike to get. Your answers are basically what I thought but I have seen some mtn bike tires that seem to be high quality but have a low thread count. Are the courser threads stronger to resist the abuse of off road use?

Personally, I'd advise simply paying less attention to tire makers' TPI claims. Higher TPI is, in theory, nice to have, but it's just one small detail in the big picture.

If you're interested in tires, I'm sure there are guys on here who'd be happy to give you opinions. Mention what kind of riding you'll be doing, on what types of surfaces (paved, dirt, gravel, etc.), what size(s) you're looking at, and how much you're looking to spend. Or just mention what tires you're looking at and ask for opinions of those.

answer is as clear
but really bike colour is
much more important

you change tires every
couple thousand miles at least
youre stuck with colour
