Behavior is the preferred spelling in American English. Behaviour is preferred everywhere else. Other than the spelling, there is no difference between the two words. The spelling distinction extends to all derivatives, including behaviors–behaviours, behavioral–behavioural, and behaviorally–behaviourally.

Behaviour and behavior are two versions of the same word. Behavior is standard in American English. Behaviour is standard in British English.

Cheap tyres will often wear quicker than premium tyres from manufacturers such as Goodyear, Michelin and Dunlop. This means you can spread the cost of your tyres, making the cost of premium quality, safer and better performing tyres much more manageable.

Michelin was a standout in our latest tests. The three Michelin models we rated all met or exceeded their mileage warranty. But the longest-wearing tire came from Pirelli. We estimate that the Pirelli P4 FOUR SEASONS Plus could last a whopping 100,000 miles.

30,000 to 60,000 miles

This is even more important on all-wheel drive cars, as any variances in tire rotation can cause undue wear on the drive system. On those cars, one unrepairable tire failure can cause you to have to replace all four tires just so that they are all even.

While there’s no federally sanctioned safety guidance on when a tire is too old to be safe, many carmakers recommend replacement at six years from the date of manufacture. An analysis of the used tire revealed that it was nearly 10 years old.

Per BRMA, unused tires over six years old should never be put in service, and all tires should be replaced after 10 years from their date of manufacture. JATMA recommends inspection after five years and replacement after 10, regardless of treadwear and overall condition. The original spare tire for Jeff’s Corvette.

Because they are rubber products, tires have a limited service life, since tire rubber compounds deteriorate over time. Regardless of wear and mileage, cracks develop in the rubber as they age. These cracks can occur on both on the inside and outside of the tire.

6-10 years

All tyres (including spare tyres) more than ten years old should be removed from service and replaced with new tyres. Verify the physical age of any car tyre by examining the markings on the tyre sidewall following the “DOT” symbol.

If a shop refuses to touch your six- or seven-year-old tires, you can try another shop, which might not be so strict. The rubber trade association, as well as Michelin and Continental, said tires can be safely used for up to 10 years, provided the tread is not worn and there is no visible dry rot.

Some vehicle manufacturers recommend that tires be replaced every six years regardless of use. In addition, a number of tire manufacturers cite 10 years as the maximum service life for tires. They do, however, require the date of manufacture to be moulded on the sidewall of every tire.

When in use, it is recommended that tyres are replaced when they reach 7 – 10 years old, (6 years in the case of caravans or trailers). On the sidewall you will find a tyre’s ‘DOT code’. One of the key pieces of information that can be gained from this is the date the tyre was manufactured.

Tyres that are aged 10 years and older will become a failure item at annual test. If these tyres do not display a date code, they will also fail. As part of the annual test, our Vehicle Standards Assessors (VSAs) will check that each tyre displays a date of manufacture or re-treading.

Tyres are considered to be “new” and fit for retail up to 5 years from the date of production. When in use, it is recommended that tyres are replaced when they reach 7 – 10 years old, (6 years in the case of caravans or trailers).

The law states: It is illegal to fit tyres aged 10 years or older to the front steered axles of HGVs, buses and coaches, and all wheels of minibuses (9 to 16 passenger seats). This will also apply to re-treaded tyres – with the date of re-treading to be marked – making the age of the tyre clearly visible.

Every tyre has an imprinted alphanumeric DOT code where the last four numbers on one side of the sidewall represent its manufacturing year. The first two digits of the four numbers denote the week of manufacturing while the latter two represent the year.

The Evidence Is Clear: Tires Should Have An Expiration Date. Older tires are substantially more likely to fail than newer ones. This is because tires are made mostly of rubber, and rubber degrades with age. Sunlight, heat, ice, and general wear and tear can accelerate the breakdown of a tire.
