What Is A Tyre?
Thick rubber ring constructed from up to 200 separate raw materials, usually filled with air, that is fitted around the outer edge of the wheel of a vehicle. Your tyre's provide your car with traction to the road surface giving your car its road grip and absorbing some shocks.
How Is a Tyre Constructed?
The tyre's skeleton is usually constructed with woven fiber cords coated in rubber. The carcass ply on the inner liner of the tyre gives the tyre it's overall strength along with woven sheets of steel wires that are coated in rubber.
How Is A Tyre Airtight?
Beads: The wheel & tyre's airtight seal is achieved using beads constructed from rubber coated high-strength braided steel.
The outer diameter of the tyre which makes road contact is designed to disperse Sheffield's road water and snow through the tyre's grooves allowing the tyre's tread blocks (peaks)to maintain road contact.
Tyre Laws AndSafety
The law states the legal tyre limit is 1.6mm of tread across the central three quarters and all around the tyre circumference. If any of your tyre's are below 1.6mm of tread then you are not only risking the safety of the vehicle driver and occupants but also a fine of upto £2500 and 3 penalty points on your license per tyre. Most tyres have wear indicators in the tread. When the indicators are level with the tyre surface area you need a new tyre.
Tyre pressure affects your fuel economy, tyre life expectancy and braking distance. Tyre pressure should be checked regular depending on your mileage but a general rule of thumb is every two weeks and before long journeys you should check your tyre pressure. Check them from cold or after very light use as your tyre air pressure varies with temperature changes unless you inflate them with nitrogen which leaks very little and responds to virtually no pressure changes with temperature fluctuations unlike air air.
