Gotta watch for rocks in the wheels, small or large. One night I a few years ago left my daughters place for the 80 km trip home. The first part of the trip is restricted to 60 kms before the freeway starts, ok all well. Soon as I accelerated on the on ramp of the freeway the steering wheel was nearly torn our of my hands, the vibrations shook the car and I had to back off back to 60kmh and take the back roads home. Unusually I did not stop on the way, caught all the lights so the rock stayed where it was
While I was parked at my daughters the council laid 30cm of fresh toppings on the service road and did not roll them in. Wheel spinning was the order of the night trying to get a grip while doing a tight turn to get up on the bitumen.
Bloody long trip home! Next morning, thinking about buggered new tyres I found the culprit. See photo.
