Fanny B Posted November 25, 2019 Report Share Posted November 25, 2019 Hi all, will a WM3 X 18 X 40 rim be ok for a 4 inch trials tyre? I`m sure I used a wm3 on the back of my Matchless but it was a long time ago. Also does the "40" refer to spoke holes? If it does it`s no good for me. Thanks in advance, Hazel 1 Quote Link to comment Share on other sites More sharing options...
Bilko Posted November 25, 2019 Report Share Posted November 25, 2019 Yes the 40 refers to number of spokes Quote Link to comment Share on other sites More sharing options...
carl ekblom Posted November 25, 2019 Report Share Posted November 25, 2019 WM3 (2.15) is what moden trials bikes use at the rear. In the 1970s WM2 (1.85) were not uncommon. WM1 (1.6) is for the front. Quote Link to comment Share on other sites More sharing options...
Fanny B Posted November 25, 2019 Author Report Share Posted November 25, 2019 Thank you Carl. I thought that was the case but it`s nice to have it confirmed. Quote Link to comment Share on other sites More sharing options...
