How to Cut OTR Tyre Cost per Hour: 9 Habits That Actually Work

When a loader tyre fails early, the first instinct is usually to blame the tyre. Sometimes that is fair. More often, the tyre was the right one and something on site shortened its life: pressure, spillage, the way the machine was driven, or a cut that was left to grow. The good news is that most of these causes cost little or nothing to fix.

Here are nine habits that consistently lower tyre cost per hour on construction and quarry equipment.

First, measure the right number

Price per tyre is easy to see on an invoice, which is why it gets the attention. The number that matters is cost per hour: what you paid for the tyre and its fitting, divided by the hours it worked before it came off. A tyre that costs 20 percent more but lasts 40 percent longer is the cheaper tyre. Without a simple record of hours, you cannot tell which is which.

1. Check pressure weekly, cold

Under-inflation is the single most common cause of early OTR tyre failure. A soft tyre flexes more, builds heat and can separate internally long before the tread is worn. Check pressures before the shift starts, when tyres are cold, against the figure for that size, ply rating and load. Fit valve caps on every wheel.

2. Clean the loading area every shift

Rock spilled from the bucket gets driven over again and again. On quarry sites with sharp shot rock, spillage is the main source of cuts. A few minutes of clean-up per shift protects every tyre on site.

3. Maintain haul roads

For dump trucks, the road is the tyre's working surface. Potholes, ruts and protruding rocks increase impacts and cuts; steep cross-falls overload the outer tyres. Regular grading and drainage pay off in tyres, fuel and suspension.

4. Train operators on tyre-friendly driving

• No wheel spin when loading. Let the bucket penetrate the pile.
• Do not articulate or steer a loaded machine while stationary on rock.
• Slow down on corners and over rough ground.
• Do not overload buckets or bodies.

Operators who understand that a loader tyre can cost as much as several months of their wages tend to take these points seriously.

5. Fit the right TRA code for the job

A standard L3 tread at a sharp limestone face will be cut up early. An extra-deep L5 on a loader that carries material long distances will run hot. Matching the tread to the job is covered in our TRA code guide.

6. Keep matched sets on each axle

Tyres on the same axle should be the same size, construction, tread code and similar wear. A new tyre paired with a half-worn one has a larger rolling diameter, so it carries more load and the axle scrubs both. When replacing a single tyre, pair it with the best of the spares rather than the worst.

7. Rotate front and rear on loaders

Loader front tyres carry the bucket load and wear faster. Swapping front and rear pairs at a planned interval evens out wear across the set, so all four come off closer together and you buy in sets rather than in emergencies.

8. Repair cuts early

A cut that reaches the casing lets in moisture and grit, and the damage spreads every hour the tyre runs. Inspect tyres during daily walk-arounds, and get significant cuts assessed and repaired promptly. A timely repair can save a tyre that would otherwise be scrapped.

9. Store spare tyres properly

Tyres age even when unused. Sunlight, heat and ozone harden rubber and cause cracking. Keep spares indoors or covered, away from electric motors and welding, standing upright on a clean surface. Use older stock first.

Bringing it together: a simple tyre log

A spreadsheet with one row per tyre is enough:

After a few months, patterns show up quickly: one machine eating tyres, one operator's shifts with more cuts, one tread type outlasting another. Those are the decisions that lower cost per hour, and they are much easier to make with numbers in front of you.
