The Writing's on the Wall

The Writing's on the Wall

The writing and symbols on the sidewall of your Toyo tyre can tell you a lot about the tyre itself, such as what weight it can carry and its maximum speed.

This helpful guide will show you what’s what, so that you can read the writing on the wall.

The writing on the sidewall of your Toyo tyre is like a specification sheet - it tells you everything you need to know about the tyre.

This information includes details of the tyre’s country of origin, size, speed rating, type approval,loading capability, model number and much, much more.

 

Of course, some of this data is stuff only a tyre technician will find useful, but there are several details you will find handy too.

Let's use the Proxes T1-S 265/40ZR17 96Y above as an example
  • Proxes T1-S - The Toyo pattern name.
  • 265 - The nominal section width of the tyre in millimetres.
  • 40 - The aspect ratio of the tyre, (the ratio between the section height and section width).
  • R - Radial construction. All Toyo’s car tyres sold in NZ are radial except for certain special tyres such as space saver spares.
  • 17 - The diameter of the rim shown in inches.
  • 96 - The load capacity of the tyre shown as an index. which should be looked up on the load index scale table here. In this case the load capacity of the tyre at the correct inflation pressure is 710kg.
  • Y - The speed symbol, i.e. the maximum sustainable speed for the tyre at the load capacity given - in this case 300kph. View the Speed Table here
  • Steel Belted Radial - as with the letter "R", this refers to the tyres construction. "Steel Belted" is a particular form of radial construction.
  • DOT - the type approval mark of the American Department of Transport, showing that our tyres have passed their strict testing procedures. When a tyre has passed both the American and European test programmes, you know you can have complete faith in it.
  • CXKA 6HY47887 - this is Toyo's production code marking, an internal code that allows us to determine exactly where and when a tyre was made.
  • E4 0213760 - the ECE type approval mark and number, showing that our tyres have been tested and passed as high-quality by the European regulatory authorities.
  • Made in Japan - the country where your Toyo tyre was made.
