How To Know If A Car Needs New Tires

Besides a flat tire, there is a number of reasons why your car tires may need to be replaced. There are certain points to be checked, legal limits involved and safety concerns. To learn about checking the status of your tires, you might want to watch this short but detailed video.

Right, I'm now going to show you how to check your tires to make sure they're safe and to see how close they are to being replaced. So, the first thing we check is we find a point in the tire to start from which is normally the valve and we look around the side of the tire for any kind of damage or defect which could be caused by curbing or hitting something in the road. What I mean by curbing is rubbing up against the curb or bouncing to many curbs.

This side is fine on the outer wall. So now, we cross our mind to the tread. Again, if we start through the valve, with the valve in a set position, we then look around the tread like so, looking in between the treads, to see if there's any cuts or any damage or any nails, screws, or anything else going that shouldn't be going on in there.

Stones are obviously fine but nails and screws would obviously be a problem. Again, we work our way around the tire, just closely looking to make sure there's no existing cracking, anything like so. Again, that looks fine.

But every tire that's manufactured is fitted with these what we call tread-wearing indicators which is actually four across this tire and they're dotted around the tire, so you go around and you see another set there. These are usually interwoven around the tire and basically, that is the legal depth of tread. If they become flat with the rubber on the tire, that shows that the tire is either illegal or is very close to being illegal.

So, that's one thing you need to look for to make sure they're always lower than the tread on the tire. The other way of testing it is with a tread depth gauge like so and basically, to use this tool, you would look at various places on the tire and you'd sit it on the tire like so, place it pushed down until the flat part is sitting on the tire. Then, remove it and on there, you could see little lines corresponding with the numbers.

This one is actually sitting on 5 so that's telling me that's 5 millimeters of tread left on that tire. So, the legal limit is 1.6 millimeters.

So, there's quite a lot of life left in this tire for the moment. There are no visible signs of any damage to the tire or so. The tire's looking in pretty good condition.

The other contributing factor to tire wear or tire problems is the pressure of the tire. If the pressure is excessive or too low, it can cause all manners of different problems. They even wear unevenly, poor handling, problems with braking.

You'll find that the weight-defined recommended pressure would either be in your handbook or consult your main dealer. To test the pressure, you'd need a tire pressure gauge which you would find in most fuel filling stations nowadays. Just remove the valve cap like so, again checking for any visible signs of damage, then you'd use a tire pressure gauge.

This, we know that the tire pressure in this vehicle should be either 30 psi or two-bar and that is actually set at 30 psi or two-bar so we now know that the tire pressure is fine as well. In conclusion, this tire's in good health at the moment. .
