Suzuki 2 Strokes

The GT250 cafe racer tires are Avon RoadRiders: 90/90-18 front & 110/80-18 rear
Am ready to mount the tires & need to pick tubes.
Per the IRC website: http://www.irc-tire.com/en/mc/products/tube/butyl/

Tube T20061 fits 90/90-18, so the front tube is an easy pick.

Tube T20062 fits 100/90-18
Tube T20063 fits 3.50/4.00-18
Tube T20064 fits 110/90-18
So which rear tube should I get?

Also, should I consider another brand?

I'd be happy with any of the three but 20063 looks the most suitable
