Aftermarket tyres

I'm searching for any source of the following aftermarket stuff for these cars. Wheels shouldn't be much of a problem but I don't see any aftermarket tyres with accurate tread patterns around.

Wire wheels and tyres - Testors/Italeri 1/25 Ferrari 250 California

Tyres - AMT Prestige 1/25 Mercedes 300SL

Tyres - Testors/Italeri Ferrari 288GTO

Wire wheels and tyres - Testors/Italeri 1/24 Ferrari 250GTO

Wire wheels, knockoffs and tyres - FDS 1/43 Ferrari 250GTO Sebring 1962

Tyres - Heller 1/24 Bugatti EB110

Heller and Italeri seem to have a thing for releasing shiny vinyl wheels with inaccurate patterns.
