How do I find the correct tyres for my car?
The information about your tyre size and model can usually be found on the sidewall of your current tyres, in your vehicle handbook, or on a sticker inside the fuel cap for or in the door jam. You can also use our car tyre search tool to find tyres by size or check car model tyres by your number plate. You can locate it inside the driver’s door on your car, inside the fuel flap or inside the glove compartment. Alternatively, you can consult your vehicle documentation and tyre manufacturer specifications. You can also find the current tyre size on the sidewall of your tyre.
What are the 3 tire ratings?
AA is best, followed by A, B, and C. This letter grade (A, B, or C) indicates the tire’s resistance to heat buildup and its ability to dissipate heat. A is the highest rating, followed by B and C. Listed in PSI (pounds per square inch), this is the maximum air pressure the tire can safely hold. A traction grade tells you how well your tire can stop in wet conditions. The highest traction grade is AA, followed by A, B, and C.As of 1997, the traction grades from highest to lowest are “AA”,”A”,”B” and “C”. A tire graded “AA” may have relatively better traction performance than a tire graded lower, based on straight-ahead braking tests. The grades do not take into consideration the cornering or turning performance of a tire.
What are C1, C2, and C3 tyres?
This new European tyre label applies to passenger car tyres (C1), light truck tyres (C2) and heavy truck tyres (C3). The C-Type tire, on the other hand, is specifically meant as a commercial-rated tire, with a higher load rating for a given size than many LT tires. These C-Type tires will show the letter “C” immediately after the wheel diameter in the tire code.
What is the 20p rule on tyres?
The 20p tyre test is really easy to do: just place a 20p coin in the main grooves of your tyre. If you can see the outer band of the 20p coin when it’s placed in the tyre, then the tyres may be dangerous and illegal and should be inspected by a tyre professional. If you don’t have a gauge, you can test your tyres with a 20p coin, as its outer rim is just under 3 mm wide. Place a 20p coin into your tyre’s tread grooves. If the outer rim of the coin is obscured, it means your tyre is comfortably above the legal minimum tread depth.
What is the 7 7 rule for tires?
If you leave them on too late, your winter tires will degrade quickly. So, when is the right time to swap? The rule of thumb is 7-for-7: wait until there are seven consistent days at 7 degrees Celsius. The reverse is also true for transitioning to winter. Tires typically last between 50,000-70,000 miles or about 6 years, depending on driving habits, maintenance, and environmental factors. Regardless of mileage, most manufacturers recommend replacement after 6-10 years due to natural rubber degradation.There is no definitive tyre age limit as to when you should replace your tyres but once your tyres reach 7-10 years old, you should keep a close eye on their condition and consider replacing them. Tyre ageing is commonly identified by small cracks, known as crazing, which appear in the tyre sidewall.The average life of car tyres in India is five years, and the tubeless tyre life in km is 50000 km. Ageing causes the tyres to wear out from the inside and outside. After five years, it is safer to replace the tyre even if there is no tread loss or visible damage.There is a general consensus that most tires should be inspected, if not replaced, at about six years and should be absolutely be swapped out after 10 years, regardless of how much tread they have left. Note that all tires have a manufacture date stamped on them.
What is the 3 percent rule on tires?
If they’re too large, they could scrape on the inside of the fender every time you make a turn. As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of the tires originally on your vehicle. As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of the tires originally on your vehicle.If you are planning to upsize car tyres, always adhere to the 3% rule. Which means the new tyre’s diameter should not be more than 3% of the stock tyres.
