Best maintenance gives perfect retread tyre wear

An example of perfectly managed RETREAD tyres through Bears Tyre Tracker that lasted 527 days and did over 258,000 kilometres. These tyres will be re-grooved to achieve at least another 30,000 kilometres on top.
Overall CPK for this set of tyres was 0.1 cents per kilometre per tyre which includes all maintenance charges.

Tyre management improves CPK

An example of perfectly worn tyres managed through Bears Tyre Tracker.  This brand (undisclosed) achieved  a 0.04 cent better CPK (per tyre) than current drive tyres used in the fleet. Bears Tyre Tracker can help select the right job specific tyre for your fleet.

Tyre Scuffing

Middle axle tyres. Middle axle being the worst for diagonal wear. Photo 1 and 2 show where the tread is actually ” SCUFFING” on the road and causing abbrasion to rubber like sandpaper to wood, due to “EXCESSIVE” jumping of tyre. Photo 3 shows where diagonal wear is starting to wear shoulders and irregularity is in 2 to 3 parts of these tyres. Left unattended it gets worse — costing operators many $$ in lost wear plus casings being damaged from fractures and separation from said “Excessive” jumping effect.

Shoulder Wear on Outer Edge

This picture is not clear but there is excessive wear on the shoulder of the tyre aboveshoulder wear 4
This is just another side of Bears Tyre Tracker. Left untouched the outer rib would keep wearing excessively losing many tens of thousands of kilometres for the operator. Servicing this type of problem is part of tyre suppliers obligation to the client. It generally ends up in the “TOO hard basket” by tyre fitters.

No Maintenance

P9220006-notatedSame tyre below as shown above from the other side – another tyre wasted due to no maintenanceP9220003
These show tyres that have not been maintained  at all except for pressure.  This is also diagonal tread wear.  Tyres typically seem ok with the amount of tread but because of 0 maintenance 50% is shot. Eventually leaving the tyre useless and costing the operator a road service to fix the problem.  Instead of tyres producing good k/ms and cases being utilized back for capping the tyres have come off premature and rendered useless.  With a  proper tyre  regime proper k/ms could have been achieved at a lower cpk rate for the client.

What’s the financial results of correct tyre maintenance?

This chart is for steer tyres only for the same type of 28 prime movers doing the same routes. They effectively became un-maintained and the results show.

Poor Alignment


These show prime mover with extreme alignment problem.  Bears Tyre Tracker will alert the operator to problems such as this immediately.  Sometimes in large fleets this could be missed for many months before required action is taken. How many sets of steers have you lost like this because of  lack of knowledge on your vehicles condition????


Poor Rotation Timing

Show tyres that were out of rotation schedule by 10 weeks. As you can see not only would there be a lot of bouncing around but the large loss of tread life costing the operator big $$$$$$

Ruined Tyres get a New Lease of Life

These tyres above have irregular wear known as scalloping due to no rotations in their 261 days of life thus far. Left unattended this scalloping would rapidly increase tyre wear and dramatically reduce the tyre life.

How many do you see in your fleet like this?


The scalloped tyres from above  have been skimmed to rejuvenate and maximise the remaining tread available.

Diagonal Tread Wear

This photograph taken of a trailer operated by a major national fleet and maintained by a big brand tyre company shows bad diagonal tread wear. Already this tyre has lost 10-15% of its useful life and untreated (as they often are) will be a large loss to the operator. For whose benefit?
If serviced or maintained through the tracker, these tyres would be skimmed to get maximum life.
These photos show 1 of 12 tyres on a foreign trailer to customer (bought 2nd hand). It clearly shows very bad diagonal wear from lack of servicing. The end picture shows same tyre 2 feet around. Over 50% of tyre loss plus one can only imagine the amount of bouncing around at 100 k/m per hour multiplied by 12 tyres in the same condition on trailer.

HOW MANY tyres in this condition can you see on your vehicles???
