Overview

RDR930 is a RESUNYOU drive axle radial pattern built for tractor units running loaded on paved trunk routes. The mixed block and rib design carries torque without tearing at the block edges, and the five deep grooves keep water moving under a fully loaded axle. It is offered in 295/80R22.5 and 315/70R22.5, the two sizes most European and African fleets buy for 6x2 and 6x4 tractors.

What RDR930 Gives the Operator

Mixed pattern puts traction blocks where the drive axle needs grip without giving up straight line stability

Longer block design spreads contact pressure so irregular and eccentric wear develops slower

Five deep grooves clear standing water at full load on wet motorway surfaces

Tiny kerfs across the blocks bite on cold and greasy tarmac in early morning starts

18 and 20 ply rating casings suit operators who plan to retread rather than scrap

Application Scenarios

• Long distance tractor and trailer work on motorways and national trunk roads
• Regional distribution running mostly paved routes with daily loading cycles
• Tipper and mixer work where the yard is rough but most of the shift is on tarmac

Who It Is For

• Tyre importers stocking a drive pattern in the two mainstream 22.5 inch sizes
• Fleet operators replacing drive axle tyres across mixed European brand trucks
• Distributors who need a mid tier drive tyre priced under premium brands

What It Is Meant To Fix

Drive tyres that wear into a saw tooth pattern and get pulled off early

Poor grip on wet surfaces when the trailer is loaded and braking distance grows

Casings that cannot be retreaded, which pushes cost per kilometre up

Technical Features

• Mixed block and rib tread for traction and braking on the drive axle
• Long block geometry to resist eccentric and abnormal wear
• Five deep circumferential grooves for water evacuation
• Kerfed block surfaces for grip on cold wet tarmac
• Radial casing available in 18 and 20 ply rating

Customisation

• Container loading planned across sizes and patterns in one shipment
• Sidewall marking and labelling to suit the destination market on request

Quality Control

• X-ray inspection of the finished casing before packing
• Dynamic balance check on the production line
• Production under ISO9001 and ISO/TS16949 systems

How It Compares

• Compared with A premium European drive tyre Lower purchase price per casing, with a shorter proven mileage record in independent fleet testing
• Compared with A steer pattern such as RSL612 on the drive axle RDR930 gives far more traction under torque, but generates more rolling noise on smooth motorway
• Compared with An on off road pattern such as RAC880 RDR930 wears slower on tarmac, while RAC880 handles gravel and site access better

Getting the Most Out Of It

• Fit to the drive axle only and keep steer and trailer positions on their own patterns
• Set cold pressure to the load actually carried on the axle, not to the maximum on the sidewall
• Check pressures weekly - under inflation is the most common cause of shoulder wear on drive tyres
• Rotate paired duals when tread depth between the two differs to keep the axle loading even

RDR930 Questions

295/80R22.5 in 18 ply rating and 315/70R22.5 in 20 ply rating. Both mount on a 9.00 rim.

295/80R22.5 is rated 3550 kg single and 3250 kg dual, 315/70R22.5 is rated 3750 kg single and 3350 kg dual, both at 900 kPa.

It is a drive axle pattern. For the steer position ask for RSL612 or another RESUNYOU steer pattern in the same size.

The casing is built for retreading, though acceptance depends on the retreader and on how the tyre was run. Ask before you commit a large volume.
