The DOT number on the tyre sidewall tells you how old a tyre is. This is an important factor for safety, regardless of the condition of the tread.
The last four digits of the DOT code indicate the week and year of manufacture
Older tyres can become brittle, even if they have sufficient tread depth
We recommend having tyres inspected by a professional once they are around 6 years old
Even a tyre with plenty of tread can become less safe as it ages. You should therefore have older tyres checked by us regularly.
