What size tyres?

[jumplead]

I'm in Australia on business but need to order some tyres that I can get them fitted on Saturday so I'm legal for Chatsworth, only I have foolishly forgotten to make a note of the size I need,

Looking at getting the rears replaced, running standard wheels on a 400, 225/50/R16 W92 comes to mind but i'm not sure. I'm looking at getting Toyo T1Rs, which size should I get?

That's certainly one of the "normal" configurations. I have Toyo T1R 205/55/R15V front and 225/50/R16W back.

Great thanks.

you require zr rated tyres

[JonathanT]

That *is* right, you should fit W/Y/Z speed rating where possible - I asked my insurance company and they were not fussed so I've fitted V rating as Toyo don't make a 15" W.

Just spoken to my insurers and they are fine with me putting W or Y on the rears instead of Zs providing the loading ratings are at least the same as the manufacturer recommended(92).
