Guys

I've picked up my MY06 Wagon, and have changed the rims to 17"x7" with 215/45/17 tyres (I'm in Singapore and the stock rims are 15").

What should the correct offset be for MY06 Wagons? I've been told my rims are offset 44, and I'm not sure this is the right offset for my wagon.

When I have a full load of passengers and crap in the boot, on my stock suspension the tyres rub on the edge of the wheel arch. I'm assuming with the correct offset, this shouldn't happen right?

Help pls!

Jono.
