Reading Your Trailer Tyre Size

Trailer tyre sizes may be written in several ways on the tyre sidewall. Tyres which are small or Crossply tend to be written in Imperial notation with the Width first and the Rim last, such as 4.00-8 or 6.00-9. Sometimes the Height is also specified as the first number followed by an "X", for example in 16.5X6.50-8 and 18X8.00-10. Larger or Radial tyres normally have the newer metric notation, again with the width first and the rim last, for sizes like 145R10 and 165R13. Many of these sizes will also give the Profile, just after the Width and followed by a "/". Examples of sizes like this are 155/70R12 and 205/75R15.

Some trailer tyre sizes will be followed by a "C". This stands for Commercial rating, meaning that the tyre will carry far more than a car tyre of the same size. Not all manufacturers use this however, and some will use a Ply Rating or a Speed Load Index without a C to show that the tyre is suitable for a trailer .


Speed & Load Index for Trailer Tyres

Most modern trailer tyres have a speed and load index, sometimes known as a service index, stamped on the sidewall. A tyre's Speed Index is the maximum safe speed of the tyre; this is represented with a letter from the very slow (A1) to the very fast (Y and beyond). The Load Index is the maximum weight that the trailer tyres can safely support. This is represented by a number: the higher this number is the more weight the tyre can carry. It is imperative for the safety of the vehicle and its occupants that tyres with high enough Speed and Load Indexes are chosen. To find out more about Speed and Load Indexes and all other tyre markings, have a look at our Tyre Size Guide.


Ply Rating

A Ply Rating is a measure of a tyre's strength, indicating the maximum load that the trailer tyres can safely carry. Tyres with a higher ply rating carry more weight but cost more due to their superior construction and the extra materials used. The exact carrying capacity of trailer tyres can vary by axle, speed, pattern, pressure and manufacturer. Tyre manufacturers often provide detailed information: please check the Technical Link of a product or Contact Us for more information.


Trailer Tyre Patterns

Trailer Road Pattern

Road Pattern

Many tyres for trailers and caravans are similar to car tyres, and are optimised for road performance. This pattern is normally found on the modern radial tyres and is ideally suited to larger road trailers.


Trailer Zig-Zag Rib Pattern

Zig-Zag Rib Pattern

The Zig-Zag Rib pattern is a general-purpose pattern for smaller road trailers and caravans. This pattern is designed to maximise service life on the road.


Trailer Lug Pattern

Lug Pattern

This pattern can be similar to the road or rib patterns but with pronounced shoulder lugs. This is for stability on small tyres with high load ratings, and is ideal for many types of caravan.

Tubed vs Tubeless Trailer Tyres

Tubed trailer tyres have a separate tube fitted inside which is often purchased separately to the tyre. Tubeless tyres have their own inner liner which prevents leaks from the rim and minimises the damage done by punctures. Tubeless trailer tyres are more resistant to overheating, but air leakage can occur if the tyre has not been fitted properly or if the rims are old or damaged. Find Out More.
