In Adelaide, where summer heat and occasional storms challenge vehicles in unique ways, the age of your tyres plays a bigger role than many drivers realise. Whether you’re driving around Magill, through the Adelaide Hills or on the coastal roads, older tyres can impact safety, performance and cost-effectiveness. In this article we explain why tyre age matters, how to check it and when to replace even if tread looks fine.
What we mean by “tyre age”
-
Define what tyre age is (manufacture date code on sidewall, e.g., DOT week/year)
-
Explain how rubber compounds degrade over time even if tread remains.
-
Mention typical industry guideline: many recommend replacement after ~6-10 years regardless of wear (depending on condition).
-
In Adelaide’s climate (hot summers, UV exposure, heat cycles) ageing effects can be accelerated.
How Adelaide and South Australia climate affect tyre ageing
-
South Australia: strong sunlight, high summer temperatures, frequent hot road surfaces → increases rubber oxidation, sidewall cracking, internal tyre structure stress.
-
Rainy periods, sudden temperature changes can also stress older tyres.
-
Local roads: some gravel, some coastal salt exposure → older tyres more vulnerable to cuts, cracks.
-
For drivers around Magill, Adelaide Hills, suburban Adelaide, consideration of local climate helps when assessing tyre condition.
Signs your tyres might be too old (even if tread depth good)
-
Sidewall cracks (small fissures), bulges or bubbles
-
Uneven wear despite correct pressure → may indicate internal breakdown
-
Hardening of rubber (less pliable), increased vibration, longer braking distances
-
Tyres with age + low use can still degrade (parks, low-km vehicles)
-
Checking the date code: last four digits of DOT code, e.g., “2319” = week 23 of 2019.
When and how often should you replace tyres based on age?
-
A general rule: consider replacement if tyres 6+ years old and used in demanding conditions; definitely if 10+ years old regardless of tread.
-
Local wear-factors: if vehicle regularly in hot sun, coastal roads, performance driving, consider earlier.
