What is your tyre wear pattern trying to tell you?

What is your tyre wear pattern trying to tell you?

Just like a picture – your tyre wear tells a story. Tyres develop different wear patterns depending on the forces they are submitted to, and the conditions they are most commonly operating in. 

Take a look at some common wear patterns below to see what your tyre wear pattern is telling you:


Why it occurs

How it occurs

Example

Premature shoulder wear
  • Too much contact with the road by the shoulders.
  • Under Inflation
  • Worn steering components
  • Misalignment
Premature shoulder wear
Premature centre wear
  • Too much contact with the road by the centre
  • Over-inflation
  • Tyres may be too wide for the rim
Premature centre wear
Feathered Wear 
(One side of a tread rib is
lower than the other side)
  • Tyre is being dragged sideways
  • Excessive toe (in or out)
  • Worn bushings
  • Misalignment
Feathered Wear
One-side Wear
(One shoulder or side of the tyre is worn more than the other)
  • Most of load on one shoulder
  • Incorrect camber setting
  • Worn joints
  • Worn K/Pin bushes
One-side Wear
Scalloping/Cupping
(Erratic dips or depressions on tread area)
  • Tyre bounces or wobbles
  • `
  • Worn or bent suspension parts
  • Out of balance condition
  • Flat spotting (brake lock-up)
Scalloping/Cupping
Heel & Toe Wear - drive tyres
(Front edges of tread blocks are higher or lower than rear edges)
  • Tread blocks distorting or not making full contact with road
  • Mismatched duals
  • Variance in pressure between duals
  • Torque stress
  • Tread/tyre design
Heel & Toe Wear drive tyres
Alternate Lug Wear – drive tyres
(Inconsistent tread block wear, up & down)
  • Tyre not making uniform contact with the road
  • Mismatched duals
  • Variance in pressure between duals
  • Poor suspension control
Alternate Lug Wear – drive tyres
Erosion Wear
(Circumferential wear along rib edges)
  • Slow wear rate of radial tyres on free rolling axles
  • Very little rubber being shaved
  • Not maintenance related, simply a function of long life
  • Should not be of concern
Erosion Wear
Shoulder Step
(Relatively even depression of outer section of shoulder ribs)
  • Typical for radial tyres on free rolling axles with a slow wear rate
  • Very little rubber being shaved
  • Not maintenance related, simply a function of long life, but can be kept to a minimum with correct pressures
  • Should not be of concern
Shoulder Step

Once an irregular wear pattern develops (due to fitting irregularities, out of balance or mechanical reasons), it will continue to develop even if the cause is removed. In many cases the only solution is replacing the tyre.
