Default Sorex Tire Numbers

Hi guys!

What does the numbers after Sorex tires mean? Same goes for other companies... What is 36R?

I'm guessing it's a hardness; which one has the longest life?

It is a compound rating for a specific temperature spec. 36R would be for a hot track condition but I don't remember the specific temps. You may be able to go to Sorex's site and get that info. I have it but it is at home and I am at work at the moment.

Not for Sorex tyres, but should give you a rough idea.

If anyone has go the same thing Sorex tyres (I couldn't find anything on their website ) that would e great.

Sorex tire ranges

24R 71~Lower
28R 68~84
32R 81~105
36R 98~158

It's a general guide line to go by. However my favorite tire is the 36R. I even use it in cold weather. Just gotta prep it right. Otherwise, it'll take too long to heat up during the race.
