B31 tyre sizes for a 1958 bike.
« on: 24 February, 2017, 18:59:45 »
Good Evening All
I'm starting the put together phase of rebuilding my B31As I've now got the wheels and hubs back together I need some tyres. Any suggestions please on good tyres to fit and the correct sizes . The off coming are both 3.25 x 19 .

I'd looked at fitting Avons but the rear seems to be only available as 3.50-19 ( Avon AM7 Safety Mileage MK II ). The front as 3.25 x19 is readily available. as the AM6 speedmaster.

Any suggestions or advice would be greatly appreciated.

The B33 of the same year was fitted with a 3.50 x 19 rear tyre. As the wheels are the same the slightly wider tyre would suite your bike.
