What is the 3% rule for tyres?
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. Where a lot of regular city or highway driving is involved, buy high-mileage car tires. For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.You can switch to larger car tyres but experts recommend upgrading within 3% of the original diameter of your car tyres. Switching to unnecessarily large tyres will not only affect your car’s mileage but may also impact handling and ride quality.Larger tires require more energy from the engine to move the vehicle compared to smaller tires, resulting in increased fuel consumption. Smaller tires and wheels demand less engine output, making them more suitable for navigating stop-and-go city traffic efficiently.
Are 7 year old tyres ok?
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. Discount Tire recommends replacing your tires at six years of age, regardless of how much tread is left. For your safety, Discount Tire will not service a tire that exceeds 10 years of age.While we recommend replacing your tires at 6 years of age, you can’t just assess your tire’s life based on how old it is. A tire’s lifespan is determined just as much by the conditions a tire is exposed as it is by calendar years.On average, tires should be replaced every 6 years, or after every 25,000 to 50,000 miles driven, as recommended by most tire manufacturers. Let’s look at the determining factors of why this is the recommendation.On average, most tyres last between 40,000 to 80,000 kilometres. However, this estimate can change based on the factors mentioned earlier. High-performance tyres may have a shorter lifespan, while touring or all-season tyres tend to last longer.
Are 10 year old tires ok to drive on?
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. It’s possible to use tyres that are 5 years old if they’re in good condition. They also need to have been properly stored. If your tyres are over 5 years old, we would recommend that you have them checked by tyre fitter. As rubber deteriorates over time naturally, older tyres can be more prone to failure.After about 5 to 6 years, tires start to show their age, with the risk of dry rot, cracks, and compromised performance. So, even though those 7-year-old tires might appear serviceable, it is probably time to buy a new set.If your tires are more than 6 years old then you should change them. The second method in determining if you should replace your tires is the tread depth. The recognized smallest safe tread depth is 2/32 inches. You ought to change your tires if it has worn down to that measurement.Years Old: Tires of this age probably have little remaining tread depth, reducing traction, stability and puncture resistance no matter the weather. They may also have cracking or structural damage caused by oxidation and environmental exposure. At this stage, we recommend replacing your tires.
