The 75th Anniversary 4/4 has wider tyres on the standard 4/4 rims...they are either 175 or 185s. The competition version of the 4/4 uses Avon CR6 ZZ tyres on the standard wheels and I'm pretty certain they are wider than standard.
As Giles says though...you don't need wider tyres on the 4/4...its pretty hard to make the back end break away!
