wondering if anyone knows of a place in Aus - ideally near Doncaster/Ringwood VIC - where I can get something like this - https://tredwear.com/product/38-red-line/ (supplied and fitted ... I hate doing fiddly shit!). Longer term would like to get the red stripe on the rims (so I don't have to re-do it with each set of tires!)

by memory, there used to be a place in West Heidelberg that dealt in antique tyres, whitewalls etc.
