Bandsaw tyres for DMB65

[Briluki]

I need two tyres for my bandsaw. Have been quoted £40.95 which I think is a bit steep as the tyres for a BAS315 are only £3.67 each. So.... does anybody know if the BAS315 tyres will fit a Drillmaster DMB65. What are the wheel sizes on the BAS315? The DMB65 sizes are 310 x 20 and the old tyre is 2.5 thick. My tyres are smaller than the wheel so they are a stretch fit. I believe the DMB65 was taken over by Metbo and renamed BAS315 so are they the same?

Update: As no replays I ordered two BAS315/4 WN55(gb) tyres as it was worth the gamble ... They are exactly the same as the ones quoted for £40.95 ... Delivered for £10.34. They are a stretch fit so need soaking in hot water to soften then force fit the bug**rs. Any older members will remember using mum's spoons to fit bicycle tyres ... just the same.
I got them from Miles Tool and Machinery (Part Nos MET-7232055833.3). Can't post the link www(dot)mtmc(dot)co(dot)uk
