** Check tyre (tire) tread depth, the deepest groove in a tyre has a tread depth indicator which is a small hump in the groove, the side of a tyre also has an arrow or small triangle which shows where the tread depth indicators are located
** Most tyres start with either 10/32" or 11/32" of an inch of tread. When the tread depth indicator is level with the height of the tread (2/32"), this means it is time to change tyres. The usable amount of tyre is on most instances 8 to 9/32"
** When tyres are fitted to wheels, wheel weights are fitted to a wheel to help balance the wheel/tyre combo and to remove vibrations when driving, the less weight fitted the better the build quality of the tyre and/or wheel in general. If many wheel weights are added, it means the build quality of the tyre or wheel may be poor
