Furthermore, tyre manufacturers define the minimum cold inflation pressure for every vehicle. Minimum cold inflation pressure provides tyre main performances. The manufacturers of Original Equipment tyres specify recommended tyre pressure that optimizes other performances handling, comfort, fuel consumption.
Recommended tyre pressure differs from the minimum cold inflation pressure but can never be lower. The recommended tyre pressure tyre press check tyres be found on the tyre placard which is usually located on the door edge. The placards lists, as a minimum, recommended tyre inflation pressure for normal vehicle load.
These weaknesses are manifested by:. Excessive wear in the central part of a tyre tread indicates that a pressure is higher than the recommended pressure.
How do I know when my tyres are worn?
The mileage of tyres driven over inflated is decreased. Excessive wear in shoulders area of the tread indicates that a tyre is under inflated. Under inflation can lead to tyre premature tread wear as well as tread separation in cases of severely under tyre press check tyres.
It means loss of km mi tyre press check tyres possible km mi. Tyre flexes and heats during wheel rotation. Flexing and heating of an under inflated tyre is greater and structural internal damages of tyre and tyre failures are possible.
Excessive load along with the under inflation can lead to increased tyre flexing and damages.
Therefore, tire pressure should be adjusted in relation to the load. When tyre rolls at high speeds, its parts can separate. This occurs especially in warmer tyre press check tyres. The consequences of tyre separation could be disastrous.
Separation of the tyre press check tyres belt frequently leads to dangerous tire blowouts resulting in vehicle loss of control and rollovers. Maintaining the proper tire inflation pressure is crucial because it affects numerous vehicle and tyre performances, safety and environment:. Nearly all of these manifestations of the tyre pressure impact are correlated and cannot be considered separately. Handling represents the ability of a vehicle to negotiate curves and respond to road conditions.
Every driver knows that with underinflated tyres is more difficult to steer and respond to road is slower.
There is tyre press check tyres long list of factors that influence vehicle handling along with tire pressure road surface conditions, tread depth, inappropriate speed, vehicle steering characteristics, tyre cornering capabilities etc.
Handling of a vehicle with under inflated tyres is reduced during the lane changing and cornering. Lower air pressure affects on reduced tyre stiffnes and lower cornering tyre press check tyres. Accordingly, the result of lower tyre pressure is poor handling. When cornering in a curve with underinflated tyres the vehicle strives to go straight and requires greater steering angle to generate the same cornering force.
How to check your tyres — tread depth, pressure and damage explained and how to do the 20p test
When the vehicle changes the lane with the underinflated tyres a sidewall stiffness decreases and the handling is weaker. Many scientific and safety organizations have tested the impact of low tire pressure on vehicle stopping distance.
The general conclusion is that stopping braking distances with underinflated tyres are increased, both on the track — straight line or when cornering. With tyre pressure at 2. Hydroplaning occurs on water covered road surface "…when a wedge of water in front of the tyre lifts the tyre press check tyres off the road in the same manner that a boat planes hydroplanes on water when it reaches a sufficient speed and has a flattish underwater shape" John Bullas.
When the hydroplaning happens tyres lose contact with the road and have a little or no traction at all. Underinflated tyres on the complete water covered road, increase the potential for hydroplaning aquaplaning and much longer stopping distances. The resistance to hydroplaning depends on the tread design efficiency in water evacuation, or how much water it can remove from the tread.
Severely underinflated tyre, under rainy conditions, become concave and traps the water in the tread tyre press check tyres and cannot remove the water. Surveys of tyre press check tyres tyre durability have shown that there is a correlation between underinflation and tyre durability.
When should I check tyre pressure? You should only check your tyre pressure when the tyres are cold. ‘Cold’ means that the car hasn’t been driven for a couple of hours. The pressure inside your tyres increases as they heat up. If you set your pressures when your tyres are already warm, their pressure will probably be too low.
In other words, underinflation causes durability reduction as in the following example:. These figures refer to driving with continuously under inflated tyres. Tyre rolling resistance is the force resisting the motion when a tyre rolls on a surface. If choosing an appointment on a bank holiday please bring your vehicle to centre at rather than the as shown. Your tyre tyre press check tyres can be found on the sidewall of your current tyre and is a sequence of numbers and letters.
The first three digits.
This displays the width of the tyre in millimetres. A tyre marked tyre press check tyres measure mm across the tread from sidewall tyre press check tyres sidewall. The fourth and fifth digits of the tyre code that immediately follow the tyre width. The aspect ratio or profile height of the tyre sidewall is expressed as a percentage of the tyre width.
The next two digits represent the size of the wheel rim that the tyre can be fitted to. It is also the diameter of the tyre from bead to bead.
So a tyre marked 16 will fit on a inch wheel rim. The speed rating of a tyre is represented by a letter of the alphabet at the end of the tyre size code and indicates the maximum speed capability of the tyre. Tyres receive a speed rating based on a tyre press check tyres of tests which measure the tyres capability to handle a set tyre press check tyres for a prolonged period of time.
Checking your tyre pressures regularly helps to keep you safe on the road and save you money
If you are unsure what speed rating you need, be sure to check your vehicle handbook. Choosing a lower speed rating than that recommended by your vehicle manufacturer could potentially invalidate your insurance.
