Your car’s tyre pressures are incredibly important to get right since they set how much grip you have to the road. Think about it, your tyres are the only points of contact you have between you flying at 80MPH down the motorway and the ground, and having one or all of those tyres being too low or too high can mean a whole lot of danger and trouble. On top of that, having the right pressure can also save you money on fuel as your engine has to work less hard to achieve the same speeds. So, I hope it’s obvious that you should check your pressures, but how do you do that? When should you? How do you find what pressures they should be at? And how can you feel a low pressure tyre while you are driving? Well, let’s answer all those questions now starting with how to check.

Thanks for the video. I filled up the tyres but the light stayed on. I didn’t realise you had to reset it. Thanks for the information I was going to go mySkoda dealer for a check-up. You saved me the trip.
Brilliant video mate
I'm not sure how long it takes to fully heat up a tyre on the road, but there was an interesting bit of info on KSR Performance & Fabrication's channel - when they were tracking a Viper (Road to America), Kevin was saying about starting each wheel at a different pressure, to allow room for the heat generated by the track - so they all end up at the right pressure after about 3 laps...
He also showed how much the tyre moves on the wheel due to acceleration and breaking while not having enough pressure in.
IMPORTANT - (Only ever reset your cold temperatures, not your warm temperatures - this is vital) Please disagree if you think I’m incorrect. For the average car and sports car, If you are ever in doubt go to a supermarket or Kwifit and use between 38- 41 psi. If it actually pulls air out of tyre because they are at 47 PSI then allow it to and reduce down to between these pressures. Then, find out immediately somehow what your pressures are. The indicated pressures on the side of your car are usually cold pressures. So, get home and on a flat surface, wait several hours or over night first thing in the morning and check your pressures using a simple £6 electronic pressure gauge from Halfords or Autozone if you are American.
So, I have 20inch alloys and the rears have to be 39psi cold and the fronts are 41psi cold. So when they are heated up after several miles of driving they read about 44-46psi.
So, if in doubt find the nearest petrol station closest to home. Inflate your tyres to 45PSI. Then, in the morning check them using the electronic gauge. If they are showing 42 on my rears, I then let a bit of air out and keep checking them until they are at 39psi. And then I do the same with the front. I over inflate them to say 45-46 psi. Then in the morning if they are still showing 43psi. I will let air out until they are 41psi.
To be really accurate drive your car backwards and forwards slowly about 2-3 metres and then check your cold PSI.
IMPORTANT - in big temperature differences the tyres increase in cold pressure. So in the UK. It it’s between 2 Celsius and 10 Celsius they will usually be fine. However, when it gets up to 15 Celsius and in summer 20-35 Celsius, your cold pressures will have increased a lot, so check the cold pressures as they will have increased quite a lot. The same from going from summer temps to cold winter temps
Hi the tyre pressure gauge on my car read differently to tescos air pressure machine. The rear right is always 3 psi lower than the others but when we put the air in using the machine, it says the correct pressure is in them all. Then when I check the dash, it still reads incorrect. Does the 3 psi make a difference? What else could we do to get the balance right? Love the wheel animation and great, clear advice.
Hello! The device that measures the pressure in each wheel to send to your car's gauges can be a little off sometimes. Often they have a note in the owner's manual about "Calibrating" them, where you fill the tyres to the correct pressures then "zero" the sensors in the wheels, but if you are checking the pressures and they are all correct I wouldn't be too worried.
Geez, he spelt Tyre correctly, he must not be American 😊🇦🇺
I don't know how's or what the correct pressure of my tires 205/50R 17 93V? A miniVan
Watch the video again.
Oh
Hi, my tyres are 235/50zr18. these are not the standard tyre size on the vehicle though. They state on the tyre not to inflate over 50 psi, so I checked my manual. and on the vehicle door which says on the front (380/3.8 kpa/bar) or 55 psi. and on the back (420/4.2 kpa/bar) or 61 psi. how do get the right tyre pressure. I can't inflate to 61 psi if the sidewall state not to go over 50psi.? thanks
What car do you have? Most cars are 30-35 psi. I have never heard of a car that recommends even close to 61 psi…
You are confusing yourself. Although you checked your manual, you don't have those standard tires. Simply just check the psi on your current tires. I have 19" wheels on my car. Although, they're not the actual size that came with the car... I must use the psi shown.
What car do you have bud?
This is really important as 55psi even when cold is extremely dangerous. 55psi when heated up could be 60 psi and that’s extremely dangerous
Cold pressures are when you go to your car first thing in the morning and check them
