It could be argued that tyres are the most important things on your car as they maintain grip to the road and allow your car to move, so why do car owners know so little about them?
Temporary spares have lighter construction to limit their weight on your vehicle so they don’t have the same speed or mileage capabilities. This could affect your vehicle’s stability.
When should you rotate your tyres? Generally speaking, it is recommended that you rotate the tyres on your vehicle once every six months, or 6,000 miles – whichever comes first.
The purpose of the TPMS (Tyre Pressure Monitoring System) is to alert you when tyre pressure is too low and could to create unsafe driving conditions.
Tyres should be cold when you check tyre pressures – preferably they shouldn’t have driven more than 3 miles
Keep tyres at the pressure recommended by the vehicle manufacturer. Incorrect pressures can affect a vehicle’s handling, cause premature tyre wear and damage a tyre irreversibly.
When it Comes to Tire Inflation, Nothing is Everything! What makes nitrogen such a great inflation gas for tires? Actually, nothing… or more precisely, the fact that it is nothing.
The tread on your tyres should never fall below 1/16 of an inch (1.6 millimeters) in depth. If you regularly drive on slick, wet surfaces, you’d be even better off with twice that much.
The science and the technology that has gone into producing even the best quality of tyre will go waste if the tyres are not inflated to the recommended pressure – Pressure comensurating to the load carried.
