Size, age and tread 4
- Tyre pressureConvert tyre pressure between psi, bar and kPa, see how temperature changes it, and find what to fill to today so the tyre is right on a hotter or colder day. #T898
- Tyre sizeType the size printed on your tyre, like 205/55 R16 91V, and see in plain words how wide and tall it is, what wheel it fits, how much weight it carries and how fast it is rated, with a picture of each part. #T940
- Tyre ageType the 4 digits from the DOT stamp on a tyre to see the week and year it was made, how old it is, and whether it is time to have it checked or replaced. #T941
- Tread depthType your tread depth in mm or 32nds of an inch and see if the tyre is legal, close to the limit or needs replacing, with coin tests and wear-bar checks you can do at home. #T942
Weather and seasons 2
- Winter tyresTap the mark on your tyre, then add tread depth, age and a cold pressure check, to see if your tyres are ready for snow, with the winter tyre rules for Canada, the USA and the UK. #T943
