Wheels and Tyres

** 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

Oil Changes

Basic tips I follow when doing my own oil changes -

** Make sure the hand or foot brake is on. If car is auto, put selector in park, for manual leave in 1st gear

** Place brick behind either rear wheel

** Change oil when the engine is warm, wear disposable gloves so you don't get burned or get your hands covered in used oil, keep rags or paper towels close by in case of mess

** Remove the oil cap and dipstick when draining oil to drain oil trapped by engine vacuum
