Size - this is the manufacturer’s sizing and must match the size or your wheels. This can be confusing as tyres have had different sizing systems over the years, and there are many (sometimes conflicting) sizes available. For this reason it’s important to check the ISO diameter too for clarification, especially for 26” wheels.

Bike Type - the type of bike the tyres were designed to be used on. Road tyres will generally be narrow with minimal tread, touring tyres wider with a bit more grip in the tread, and cyclocross & MTB tyres wider still (especially the latter), with a much more pronounced tread pattern.

ISO Diameter - this relates to the diameter of the wheel rims at the point where the tyres are seated (bead seat diameter). This is a universal measurement, often displayed on tyres as 28-622 or similar, 28 referring to the tyre width and 622 being the ISO diameter in millimetres.

TPI - stands for threads per inch and refers to the thread count of the tyre casings. A high thread count usually means more supple and lighter tyres, this can be anything as high as 320 tpi. We can’t always provide this information however, as it’s not always possible to know for sure.
