Tyres Decoded

Tyres have a lot of numbers and letters on the side — but they’re not as complicated as they look.

Here’s a simple guide to what matters when you’re checking or replacing tyres.

What you’re looking at

All those markings on the side of your tyre tell you its size, strength, and limits.

It appears in this order:

Width
Profile
Tyre construction
Rim size
Load index
Speed rating

Width

How wide the tyre is (in mm).
Wider tyres can give more grip, but may use a bit more fuel.

Profile

How tall the sidewall is compared to the width.
Higher profile = more comfort.
Lower profile = sharper handling.

Construction

This tells you how the tyre is built.

Most modern tyres are radial (R) — the standard for everyday vehicles, utes, tractors, and most farm and road use.

You may also see:
Bias (B) – A tougher, stiffer tyre often used on trailers and older farm equipment.
Bias belted (BB) – A less common option that sits between bias and radial.

Load Index

What does it mean?

The load index tells you how much weight each tyre can safely carry when it’s properly inflated.

Check the number on your tyre and match it to the table below to see its load capacity. It’s important this meets — or exceeds — what your vehicle needs, especially for utes, trailers, and loaded farm gear.

Load Index	Max Load (kg)	Load Index	Max Load (kg)	Load Index	Max Load (kg)	Load Index	Max Load (kg)	Load Index	Max Load (kg)	Load Index	Max Load (kg)
60	250	85	515	110	1060	135	2180	160	4500	185	9250
61	257	86	530	111	1090	136	2240	161	4625	186	9500
62	265	87	545	112	1120	137	2300	162	4720	187	9750
63	272	88	560	113	1150	138	2360	163	4875	188	10000

Speed Rating

What does it mean?

The speed rating is the letter at the end of your tyre size. It shows the maximum speed the tyre is designed to handle safely.

Match the letter on your tyre to the table below to see its rating. When replacing tyres, it’s best to stick with the same rating or higher.

For most everyday driving, it’s well above the speeds you’ll actually be doing — but it still needs to be right for your vehicle.

Speed Symbol	Rating	Speed Symbol	Rating (km/h)
E	70	R	170
F	80	S	180
G	90	T	190
J	100	U	200
K	110	H	210
L	120	V	240
M	130	W	270
N	140	Y	300
P	150	Z	240+
