TYRE SIZE GUIDE
How to Read a Tyre Size in South Africa
Understanding the markings on your tyre sidewall helps you request a more accurate quote and compare suitable replacement options.
IMPORTANT SERVICE-AREA NOTE
National information, one physical workshop
These South Africa pages are vehicle-care information and enquiry resources. Top Point Fitment Center's physical workshop is at 112 Turf Club Street, Turffontein, Johannesburg South. This website does not claim Top Point branches in other South African cities or provinces. Product sourcing, fleet support or workshop availability must be confirmed for the specific enquiry.
Example: 205/55 R16
205 is the nominal tyre width in millimetres. 55 is the aspect ratio, expressed as a percentage of the tyre width. R indicates radial construction, while 16 is the wheel diameter in inches.
Load index and speed rating
The characters that follow the size provide additional specification information, including load and speed capability. Replacement tyres should meet the appropriate vehicle requirements rather than matching only the first three size numbers.
Where to find the correct specification
Check the current tyre sidewall, the vehicle tyre-information placard, owner documentation or manufacturer information. If the vehicle has non-standard wheels, confirm suitability before ordering replacement tyres.

FREQUENTLY ASKED QUESTIONS
South Africa vehicle-care questions
Can I use a different tyre size from the one currently fitted?
A different size may affect clearance, gearing, handling and safety. Changes should be checked for suitability rather than assumed to be interchangeable.
What if I cannot read the tyre sidewall?
Send the vehicle make, model, year and a clear photo if possible. A tyre professional can help identify the information needed for a quote.
Does the load index matter?
Yes. The replacement tyre needs an appropriate load capability for the vehicle and application.
