The obvious answer to this question is when your old tyres are worn out. So there are a few factors to consider when determining this, which include, when is it the easiest or the most convenient time to do the change. If we start with the ways to determine if you need to change the summer tyres, it is often due to the fact that the thread depth is below the recommended 4mm, the legal threshold is 1.6mm, but trust me, you do not want to go that low.
If you are planning to anyway change to winter tyres at the end of the season and you are currently close to the depth of 4 mm, then it is probably more convenient to change at the end of the season, if the season is soon coming to an end. If your thread depth is below 4mm, you should change immediately. The thread depth is there to guarantee you your safety. It both ensures you have maximal grip on the road, so that you don’t start skidding when you take turns and it ensures that you can drive safely, even when there is water on the roads.
If you are driving with worn out tyres on wet road, there’s a bigger risk that you lose control over your car as the tyre can’t push the water away to the sides. This is what we call aquaplaning. When aquaplaning occurs you have lost contact with the road, and you can’t control the car anymore, as you are now gliding on the water surface like a boat does. This loss of contact and control over your car can be very dangerous.
Also you need to change your tyres, if they are damaged, if the sidewalls have been damaged, or if there is wear on the structural parts due to hitting some rock or curb. It is recommended to change the whole set, if possible, at least if the other tyres are getting close to the end of their lifecycle. You don’t want to drive with a mixture of new and old tyres.
How often should you check the condition of your tyres, depends on a few factors. First it depends on how old your tyres are. If you have a brand new set of tyres on your car, you do not need to focus on the tread depth. You should still check the tyres for possible damages that can have occurred when you are driving, especially if you have heard some noise while driving or if you might have hit the curb while parking. A visual inspection on a monthly basis should be enough to spot any visual defects that might have occurred while driving.
You should also check the tyre pressure on a regular basis. This should be done when the tyres are cold, and not after hours of driving. If you do not have a gauge at home to measure the pressure, try to do it at the petrol station when you fill up the car. Try to do this as early as possible of your drive. To have wrong tyre pressure do more harm than you can think of. It affects the road safety of your car and it also directly impacts the fuel efficiency of your car. So this should be checked at least monthly or as often as you feel it is necessary.
The tread depth becomes more important, the longer you have used your tyres. If you keep the same set of tyres on the car for the full year, we recommend that you check it every quarter. There is also a need to rotate the tyres to even out the wear between the front and the rear tyres. It is recommended to rotate the tyres every 8000 km of driving or when the difference in tread depth between the tyres has reached 2 mm.
In case you have summer tyres on all year or if you have all weather tyres on the car, do the check quarterly. If you alternate between summer and winter tyres, you might do the rotation when you change the tyres. If you keep checking the tyres and making sure that they are in good condition, have good tread depth and the correct tyre pressure, then you will have peace of mind on the road.
The two best ways to determine if your suv all weather tyres are worn out, is by visual inspection and by measuring the tread depth. The first one, the visual inspection, should be done on a regular basis, just to check that your tyres look to be in good condition. Here you look for any visual damages, if the pattern still looks good and if the tyres look inflated. This will not take you too many seconds and can easily be done while you are at a petrol station filling up your car or before you leave home. This will give you a quick idea of the status of your tyres. This is very important if you do a lot of off road driving in tough conditions.
The second step, is checking the tyre depth. This can easily be done with for example a coin. You just press the coin into the tread depth to see how deep it goes. You should have at least 4 mm of tread depth left to be on the safe side. If you don’t feel like checking all four tyres, check at least one of the front tyres and one of the back, as the wear may be different. This is also why it is recommended to rotate the tyres, by switching the front tyre to the back and vice versa. You should plan to do it when the difference in tread depth is more than 2 mm. You can plan to do it every 8000 km, if you don’t want to keep measuring the difference.
It is important to make sure that your tyres are in good shape and that they have adequate tread depth. By rotating the tyres you save money by not having to replace the tyres prematurely, while also keeping the tread depth on a good level on all wheels. As it is always recommended to change all the tyres at the same time, the rotation is very important. You can’t help if a tyre is damaged along the way, but this will rarely happen. We all know that off road driving can be quite extreme, but if you plan to drive a lot off road, all you need to do is to buy a tyre that has been designed for this purpose.
A great All Weather tyre has been designed for the conditions it will be used. These tyres can perform well on the road in all four seasons. The rubber compound of all-weather tyres must maintain the correct properties even though the weather changes from summer to winter. As you can imagine, this puts a lot of pressure on the manufacturer to produce a high quality all weather tyres, when the specifications are so wide.
You don’t want the tyre to get too soft, as this will increase friction and will affect your fuel economy. You also don’t want the tyre to get too hard and stiff as that reduces the handling and driving performance.
For off road conditions, the tyres are reinforced for heavy wear, which is not necessary for normal road driving conditions. What you do need though is that the tyres have been adequately designed also for rainy conditions that can occur during the summers. In summer you might experience even quite heavy rain. A well-designed tyre will be able to manoeuvre you safely through water puddles without losing control and grip.
Even a high quality tyre requires proper maintennce. Easiest way to make sure that you properly maintain your tyre, is to visually look for defects, measure tread depth and make sure that the tyre is properly inflated. Check the instruction manual for the correct tyre pressure as it depends on the use and the load of the car. So when you invest in a new set of tyres, make sure that you have this in the back of your mind, so that you make your purchase wisely.
Are you one of the people who dread the hassle of changing tyres twice a year? If you are, you should seriously consider buying an all-weather tyre. This tyre is designed for use in countries that experience moderate weather patterns all year round. Countries such as the United Kingdom where the winters are less severe are the ones suited for the all weather tyres. Also known as all season tyres or four season tyres, they are designed to cope with climates that are not too extreme. They combine elements of winter and summer tyres to create a product that features benefits of both. Continue reading “Know Your Tyres: All Weather Tyre “
