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
