Tyre Expiry and Road Safety: What You Need to Know
Understanding Tyre Expiry Dates
Tyres have a manufacturing date encoded in the DOT (Department of Transportation) code found on the sidewall. This 4-digit code represents the week and year of manufacture. The first two digits indicate the week (01-53), and the last two digits represent the year.
Regardless of tread depth or visual condition, tyres should be replaced after 5-6 years from the manufacturing date due to rubber degradation, which can lead to sudden failures and safety risks.
Why Tyre Age Matters for Safety
Studies of tyre safety show that maintaining proper tyre pressure, observing tyre and vehicle load limits, and replacing aged tyres are critical for road safety. Even tyres with good tread depth can become dangerous as the rubber compounds deteriorate over time.
Environmental factors such as heat, UV exposure, and ozone accelerate rubber aging, making regular age checks essential for vehicle safety.
How to Find and Read Your Tyre DOT Code
1. Locate the DOT Code
Look on the sidewall of your tyre for text beginning with "DOT". The code may be on either the inner or outer sidewall.
2. Find the Date Code
The manufacturing date is the last 4 digits of the DOT code. For example, "1225" means the 12th week of 2025.
3. Calculate Age
Use our calculator above to determine the exact manufacturing date and whether your tyres have exceeded the 5-year safety limit.
Signs of Tyre Aging
- Cracking: Small cracks in the sidewall or tread area
- Hardening: Rubber feels hard and inflexible
- Discoloration: Unusual color changes or fading
- Vibration: Unusual vibration during driving
Tyre Safety Best Practices
- Check tyre age every 6 months after 3 years
- Maintain proper tyre pressure at all times
- Rotate tyres regularly for even wear
- Replace tyres in sets for optimal performance

Frequently Asked Questions About Tyre Expiry in South Africa
What is the expiry date on tyres in South Africa?
In South Africa, tyres should be replaced after 5-6 years from the manufacturing date, regardless of tread depth. The manufacturing date is found in the DOT code on the sidewall. While there's no specific legal expiry date, industry standards and safety experts recommend replacement after 5 years for optimal safety.
How do I check my tyre expiry date?
To check your tyre expiry date: 1) Find the DOT code on your tyre sidewall,2) Look for the last 4 digits (e.g., "1225"), 3) The first two digits are the week (12) and last two are the year (25). Use our calculator above to determine the exact manufacturing and expiry dates.
Are 7 year old tyres too old?
Yes, 7-year-old tyres are definitely too old and unsafe to use. Tyres older than 6 years pose serious safety risks due to rubber degradation, even if they look good. The rubber compounds break down over time, leading to reduced grip, potential blowouts, and compromised handling. Replace them immediately.
When to replace tyres in South Africa?
Replace tyres in South Africa when: 1) Tread depth reaches 1.6mm (legal limit),2) Tyres are 5-6 years old from manufacturing date, 3) Visible sidewall cracks or bulges appear, 4) Uneven wear patterns develop, or5) After any puncture damage to the sidewall.
Is it okay to use an expired tyre?
No, it is not safe to use expired tyres. Expired tyres have degraded rubber compounds that can cause sudden failures, reduced braking performance, poor wet weather grip, and increased risk of blowouts. Using expired tyres puts you, your passengers, and other road users at serious risk.
How old can tyres be legally?
In South Africa, there's no specific legal age limit for tyres, but they must meet theminimum tread depth of 1.6mm. However, safety regulations require tyres to be roadworthy. Most insurance companies and safety experts recommend replacement after 5-6 years regardless of tread depth.
Do tires expire if not used?
Yes, tyres expire even if not used. Rubber degrades over time due to oxidation, UV exposure, temperature changes, and ozone. Unused tyres stored properly may last slightly longer, but should still be replaced after 6-10 years maximum. Heat and poor storage conditions accelerate aging.
How to tell if tires are expired?
Check if tyres are expired by: 1) Reading the DOT code for manufacturing date,2) Looking for sidewall cracks or crazing, 3) Checking for rubber hardening, 4) Noting any unusual vibrations while driving,5) Observing discoloration or weathering signs.
What is the life of a tyre in KM?
Life span of a tyre in KM is 60,000-80,000km. Tyre life varies by type and usage: Budget tyres: 40,000-60,000km,Mid-range tyres: 60,000-80,000km, Premium tyres:80,000-100,000km+. However, age limits override mileage - replace tyres after 5-6 years regardless of kilometers driven. Driving habits, road conditions, and maintenance significantly affect tyre life.
