I had both my front tires replaced with Michelin PS3 after surveying a few shops and finally settled for this shop in Bukit Kemuning as their offer was the best.
Balancing was free, however they were reluctant to say how much their price for chamber adjustment was. Upon replacing my tires and hooking up their alignment machine I found all four wheels out of alignment slightly. This is when their ax begin to swing. It was RM20 per tire. This also raised my suspicion since the car was driving straight before I replaced the tires.
Upon reaching home I got my pressure gauge out and measured the pressure of both the newly replaced front tires and found the right hand front tire pressure at 275 Kpa and left front tire at 325 Kpa. The recommended tire pressure is 200 Kpa for my wira. The tire size is 195/55/15.
So this brings out the question does tire pressure effect the wheel alignment and have I been cheated by this shop?
