While it is technically possible to replace just one tyre, it’s generally recommended to replace at least two tyres at a time, preferably on the same axle, to maintain even wear and balanced handling. If the other tyres are still relatively new and in good condition, replacing one tyre with the same type and brand may be acceptable. However, significant differences in tread depth or tyre type can affect your vehicle’s stability and performance, so it’s best to consult with a tyre professional before making a decision.
