Truck Tyre Sizes and Ordering Checklist

Green truck with a Grenlander-branded trailer on a mountain highway

A truck tyre enquiry should identify the exact specification and its intended application. Send the model, full size, load and speed information, intended wheel position, quantity and delivery postcode together. Have suitability confirmed for the vehicle and operating requirements before placing the order.

Brand image above: this scene does not identify an Australian delivery fleet or confirm a particular tyre fitment.

Identify the model and intended wheel position separately

Do not infer steer, drive, trailer or all-position suitability from tread appearance alone. Name the proposed model and state the wheel position required. Where a listing or older catalogue gives conflicting information, ask the supplier to confirm the application before ordering.

Start with the current Grenlander truck tyre range. Individual pages such as AA112, AD683 and FT162 let you inspect the listed specification rows; those rows still need to be checked against the actual application.

Compare the listed truck tyre positions

Use this table to find the current website listing for each model, then open its size table to identify the exact variant for your enquiry. Include the intended wheel position alongside the full specification.

The classifications above follow our current product listings. An all-position label does not replace checking the exact specification and vehicle requirements. Confirm the proposed variant and intended application with the team before ordering.

Truck tyre size example: AD683 11R22.5

AD683 product image. The specification below comes from its catalogue table; this image is not a close-up confirming the markings of a supplied tyre.

The current AD683 specification table lists 11R22.5, 148/145M, 18 PR. Keep the three fields together in an enquiry. This is a catalogue-reading example, not an approval for a particular truck or axle.

Reading the AD683 catalogue example
Entry Meaning / order record
11 Nominal tyre section width in inches in this size notation.
R Radial construction.
22.5 Rim diameter in inches; not the full tyre diameter.
148 / 145 Load indices for single / dual use. The AD683 table lists 3,150 / 2,900 kg per tyre respectively.
M Speed symbol. Record it with the load indices.
18 PR The catalogue’s ply-rating entry; keep it as a separate field.

Size notation reference: Michelin Truck Tire Service Manual, truck tyre size markings. Single/dual service-description reference: European Commission tyre parameter explanation. These explain the codes; they do not validate Grenlander fitment or Australian stock.

In your order record, keep the model and specification in one line, then enter the intended wheel position, operating use and quantity separately. Read the load index and speed rating guide for a short code-to-value reference. Have application and any proposed alternative checked before approval.

Enquire about the AD683 11R22.5 catalogue specification.

Keep the complete specification together

Check Information for the enquiry
Pattern Exact model name
Size Full size designation, including relevant markings
Load information Required load index and any relevant single or dual values
Speed and construction Required speed rating and listed construction or ply-rating information
Application Intended wheel position and operating use
Order details Quantity by specification, business contact and delivery postcode

Describe the work the tyre will do

Explain whether the enquiry concerns highway, regional, urban or mixed operating use, as applicable to your fleet. Include the requirements already established by the vehicle documentation and your tyre professional. A general description of the route cannot substitute for the required size, load capacity or approved application.

Check each order line

For a mixed order, give each model and specification its own quantity. Keep size and load information on the same line so the supplier can identify the requested variant. If an alternative is proposed, check the full replacement specification and intended application before agreeing to it.

Ask for any missing information explicitly. A model description, a manufacturer performance graphic or an image of a truck does not establish the required specification for your vehicle.

Keep truck job lines separate from a general stock order

For tyre shops servicing commercial operators, attach an internal job or customer reference to each enquiry. When several vehicles or wheel positions are involved, split the request into separate lines rather than sending one combined tyre quantity.

Truck order handover record
Field What the shop records
Job reference Your internal reference linking the enquiry to the work request.
Application and specification The intended wheel position, operating use and full specification verified for that job.
Requested and quoted variant Both entries, with any difference clearly highlighted.
Quantity and timing Quantity per line, requested date and supplier-confirmed supply arrangements.
Approval Who checked an alternative and whether the order is still awaiting confirmation.

Check the delivery against the approved order

At receipt, compare the delivered model, full specification and quantity with the approved order and delivery paperwork. Set aside any discrepancy for resolution with the supplier before allocating that line to the job. This is an order-accuracy check; the workshop’s normal technical inspection and fitting checks still apply.

Confirm supply and delivery arrangements

The website’s manufacturer specification tables describe a catalogue range. They do not report current Australian stock by warehouse. Confirm the exact variant, quantity, price and delivery arrangements with the team for the destination postcode.

Use the wholesale enquiry preparation guide for the complete contact checklist. Send the request through Grenlander wholesale tyre enquiries, or find the listed Australian contact locations.
