Skool me on tube sizes

[kbushnz]

Hi yah All....
Quick question on tube sizing.
I have some HD tubes kicking around which I would like to run on some 35x10.5x16 Simex's.
They were in my 33 inch tyres.
Stamped on tube...
11/12.5 R15/16
Valve is the tractor style TR218A

Can I use these??? Or are they too small for the bigger diameter.

Cheers
Calvin

they should work in the 35's do the rims have big enough holes to fit the valve thru?

Yup they will have...
Weld up the old ones and drill new ones in a different location.
