Our Process

1

INITIAL INSPECTION NDT

We start our process at our NDT stations. We invested in automated machines to ensure the operator takes no shortcut in the inspection of your valuable asset. Nail hole detection is achieved by rotating the tire on a grounded roller and inserting probes with a positive charge. The operator does a visual inspection and marks any area that needs repair down the line.

SHEAROGRAPHY TIRE INSPECTION

Shearography is a technology developed by NASA to find loose tiles on space shuttles after losing the Challenger. We put the casing under different atmospheric pressures while a laser camera takes multiple pictures. If there is a hidden separation or a bad repair, this machine will show us.

It is an extra step and investment that allows us to produce a product on which our customers can depend. At Conlan Tire, every customer casing goes through this machine, which sets us apart from our competition.

AUTOMATED PLATED HUB BUFFER

Most buffers use an expandable hub to inflate and hold the casing during the buffing process. Inflatable hubs allow the tire to have a slight bounce during the buff, causing the tire to be out of round. You cannot achieve fuel efficiency or have proper runout with a tire that is out of round. Plate style buffers are more expensive than inflatable hub type.

It is worth our extra investment to guarantee all customer tires retreaded in our facilities are perfectly round. We use only plate style buffers.

SKIVE STATIONS

Rust is like cancer. If you leave a little, it will spread. The rust will spread over time causing separations and failures on the road. We have a zero-tolerance policy on rust at Conlan Tire.

We spend more time than anyone in the industry removing rust at our skive stations, even though most retreaders think leaving a little rust is acceptable.

REPAIR STATIONS

We like our tire repair stations to be compared to a dentist office. Powerful lighting along with proper tools and training are a must. We go above and beyond to make sure our repairs last the life of your casing.

REPAIR PROCESS

We use a special technique called a floated patch when doing a section repair. We add a layer of uncured rubber, so the patch gets vulcanized to the casing during the process. A vulcanized patch has 60 percent more adhesion than a standard repair. Most say this is overkill, but we believe there is no other way. We don’t know of any other retreaders today that practice this method.

AZ EXTRUSION

Cushion gum is the bonding rubber compound used so the retread remains adhered to the casing. It is the most expensive material used in the process. The minimum amount of cushion gum required by manufactures is 2 mm. We apply 4 mm to provide proper bonding.

We were again told by manufacturers this was overkill. We believe, though, that overkill is the secret to our success.

PRE-CURE BUILDERS

We apply the correct tread width on every tire that we are the first to touch. In our experience, we have found that in some cases retreaders put narrower treads on casings to boost profits. This causes stress on the casing and minimizes runout. If we are retreading a casing that has previously been cut-in, we have to follow what was previously done.

DOUBLE ENVELOPING

Envelopes are used in the curing process to keep air from getting under the tread while the cushion gum is curing. Everyone uses an outer envelope in this process with an arch ring that seals the envelope at the bead.

It would be easier and more cost effective for us to just use an outer envelope. But what about the patch repair you just put in the tire?

We believe the patch is just as important as the retread, and it needs the same protection during the process.

AUTOMATED STEAM CHAMBERS

Conlan Tire uses the latest, most advanced equipment to ensure our tires are built to last. Unlike most, we use steam heat to cure every tire. Steam creates an evenly heated environment, which results in a consistent cure. This is not possible with electric heat.

Mold Cure

THE REMANUFACTURING PROCESS

When a tire is made new, it is made in the same mold cure presses used in our factories. We simply recast the tread portion of the tire.

Research shows mold cure tires are more fuel efficient, dependable and cosmetically pleasing. Since the rubber is cast onto the tire, every tire comes out looking like a brand new tire.

Most retreaders don't mold cure because of the significant cost.

MONOBEAM80 ROBOTIC BUILDER

Our robotic mold cure builder ensures we put the right amount of tread rubber in all the right places. The 80 mm pin barrel allows us to extrude the most fuel efficient tread rubber on the market.

Unlike a pre-cure builder, the machine applies the product, eliminating all possibility for contamination or waste.

CIMA PRESS

Conlan Tire uses Cima bladder-style presses -- the best presses on the market. The Cima presses ensure our products get the time, temperature and pressure we need to make the industry's best remanufactured tires every time.
