Tire question

This is my first thread so forgive me if I am asking a question that has been asked 100 times. I searched and was unable to find what I was looking for. I just bought a 1976 KZ900 and need to buy some new tires for it. I am keeping the stock rim and also swingarm. From your guys experience whats the widest/tallest rear tire I can go. If there is already a thread discussing this just point it out to me. Thanks for the help!

Remember to buy bias ply tires as this bike is not set up for radials.

If I was to build a custom swing arm whats the absolute biggest tire I could put on the stock rim?
The widest tire on a stock rim would be a 130 regardless of how wide the swingarm is. The stock rim is only so wide so it can only take so wide of a tire. You can relace a wider rim on the stock hub and go much wider.

FYI, going to a wider rear tire on the stock rim basically throws away tire life. Street tires in the back wear out burning away the center strip of the tire. As the tire gets wider (keeping the rim width the same), it pushes the center section of the tire out more and makes this worse. There actually is a reason the stock tire is 4.00-18, that's what matches the rim width and holds the tire in the correct profile to the road.
