S7 Tyre Profile

wheel profile


The recommended ScaleSeven wheel profile is based on the full-size BS276:1927 Contour A, as specified in British Standard 276:1927 Contours for Locomotive Tyres (for British Railways 4ft 8-1/2in Gauge).

All dimensions have been converted to millimetres, divided by 43.5429 and rounded to 2 decimal places.

PDF information sheet (255.06 K) is available from the Group which outlines the methods for reprofiling Slater’s 7mm finescale wheels to ScaleSeven wheel profile.

Slater’s Plastikard Limited have been producing “off-the-shelf” wagon and coach wheels with the ScaleSeven profile for many years. A small range of locomotive wheels is currently being prepared, which will only be sold through the S7 Group. ScaleSeven profile wheels are also becoming available from Alan Gibson. Please see our External Links page for links to these suppliers.
