thanks guys,
i basically wanted to see if the wheel was buckled, i had a shunt at my last meeting which put the wheel/tyre into the suspension arms, the top arm that adjusts the castor broke, there are no visible signs of damage to the wheel but when i put it on a balancer it was moving around a bit but thought this could be due to holding it from the bore instead of the lug holes. BUT now i just realised if i jack up the back of the car and put it on i can check it that way.
These wheels dont take much bending!
