Tyres - The Basics

What Is A Tyre?

A thick rubber ring constructed from up to 200 separate raw materials, usually filled with air and fitted air tight, around the outer edge of the wheel. Your tyre’s provide your car with traction to the road surface giving your car its road grip and absorbs some road shocks.

Your Tyre’s Main Jobs
  • Allows your car to roll smoothly over the road
  • Absorbs minor shocks
  • Supports your entire vehicle and passengers weight

Tyre Facts

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.

What Makes A Tyre Air Tight?

Beads: The wheel & tyre’s airtight seal is achieved using beads constructed from rubber coated high-strength braided steel.

Why Does A Tyre Need Tread?

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.

A Little About Tyre Pressure

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.
