Wont get big profile ones with 17s mate.

But dont discount these ones mate, ask Danny B, he can explain.

IMO you wont see a grip advantage between Tims type and these, as tims might be higher profile but they not wrinkle wall jobs so I dont see an advantage of a high profile tyre in the respect.

Dunno how the GTR is coming on, I forgot to find out, and im off home now
