I had 2 tyres fitted to my ISUZU TROOPER by Grahams Tyres at Halfway yesterday, I was confused to see instead of using the tyre balancer to spin the tyres upto running speed the bloke just span the wheel with his hand. I asked, who I assumed was the manager, if this was normal, he said yes as they only go upto a certain speed. I didn't expect lobbing the tyre round with your hand would simulate road speed, maybe 2mph?
Over the 30 years I've been driving and been through at least 60 tyre refits including company cars etc I've never seen a wheel balancer that didn't need a speed calibration of the tyre and wheel first at speed.
Maybe I'm wrong, I do telephones not tyres
