lost wheels?
I WAS QUITE stunned to see the response to my letter headed "Veteran fitter's view" (CM 28 April). While I must bow to the fitter's greater experience of 40 years, I must answer the points he has raised.
Point one: expansion of the studs due to heat. Surely the wheels are subject to the same expansion? Although at perhaps a slightly different rate due to the coefficient of linear expansion. I'm sure this is accounted for in the manufacturer's design and is one reason for such precise torque settings. Point two: unevenly worn tyres on the same axle. Who would do this except a cowboy outfit? If wheel loss were to follow! think it would be down to the associated poor maintenance rather than the load created by a dragging wheel. Perhaps I should brake more gently in the future in case !shear my wheel studs.
Point three: lubricating the studs. "If it goes on easily it will come off easily"— I've never heard such rubbish. Rusty studs only cause inaccurate torque settings and some rotational force on the studs, which increases the inaccuracy.
No wonder there is still a wheel loss problem...
