I have just checked my old Pendolino, which always was a rough runner, and was reminded that I had removed the damaged remnants of the traction tyres as a result of reading that this would improve conductivity.
It may have improved current flow but did absolutely nothing for smooth running as the groove in the wheels is so wide.
I would like to obtain replacement tyres but as they are not available from Dapol, I am wondering whether anyone knows from personal experience, which other make might fit.
I had thought of trying Hornby traction tyres but there is a bewilderingly wide range such as M1144, S8318, X5856, X6030, X6121, X8030, X8063, X8101, X8331, X8439, X8442, X8461, X9064, X9721 X9238,
Fitted, their diameter would appear to be 9.9mm internal, 11.0mm external, so a slightly smaller size would probably stretch to fit.
I have also considered filling the groove with Bullfrog Snot but I cannot find a UK supplier at present. The former eBay supplier seems to have disappeared.
Any help will be gratefully received.
