Bandsaw tyres

[jpb1958]

Hello everyone. Newbie question. I have a 9" bandsaw and the tyres have disintergrated. The diameter of the wheel is 9¼". I read that I should buy tyres that are 2" smaller than the diameter of the wheel. Should I buy tyres that say they are for 9" wheels or should I buy 7½ and stretch to fit?

You need to buy the 9" tyres. They are already tight.
