While researching tires for my recumbent I noticed that tires had a thread count of from 60 to over three hundred. Could someone please explain the meaning of threads per inch or point me in the direction of where to learn about this. I asked at my LBS and they said that the tires with the higher TPI used a smaller diameter thread and the ones with the lower TPI used a thicker thread. Does the lower thread count mean the tires are not as good as the higher TPI? Which is better? Thanks, Rich M

Higher thread count tires are usually better. They create a more supple ride and better puncture resistance.

Check the math

Some low thread count tires will triple the number if it has a three-ply casing- they will still ride like garden hoses.

There is a great explanation on the Vittoria website. Check out the website (http://www.vittoria.com/index3.asp?lingua=en) and go to technologies, then tech info, then casing, then TPI. Also, they have the same info if you get a brochure on vittoria tires from your LBS.

there're also 33TPI low end tires

as posters above mentionned higher TPI is better. However, to my experience the diff btw 127 and 250 is insignificant. 60 and esp 33 TPI ride harsh, have higher rolling resistance and less grip; you don't want them.

I can testify to the better rolling resistance with higher thread count tires. I've had both types of tires on my bike while using rollers. Rolling with the cheaper lower thread type tires is somewhat like riding with the brakes on.

Conti's GP3000 and the 4-seasons each have 430tpi. My 4-seasons are great and 1900 without a flat.
