2024 Isuzu D-Max and MU-X allegedly suffering rapid front tyre wear due to steering geometry issues, with Mazda BT-50 'twin-under-the-skin' also called out

Some D-Max owners are reporting worn-out, illegal front tyres after as little as 9000km.

Some owners of the current generation Isuzu D-Max ute and MU-X SUV, as well as the closely-related Mazda BT-50, are reporting ongoing issues with accelerated front tyre wear they say is caused by a fundamental steering geometry flaw.

Feedback on model-specific forums is consistently pointing to rapid wear on the inside of the front tyres with some D-Max owners reporting worn-out, illegal front tyres after as little as 9000km. More common are reports of front rubber scrubbed out at or before the 20,000km mark.

When contacted for comment, an Isuzu Ute Australia spokesperson told CarsGuide, “In response to local feedback, the recommended steering geometry settings (alignment) has been revised to maximise tyre life through a wider range of operating conditions across the varying terrain and surfaces found locally.

“Owners with concerns of uneven tyre wear on their vehicle should contact their local authorised Isuzu UTE Dealership for more information. 

“Dependent on verification and if uneven wear is apparent, a wheel alignment will be carried out and dependent on the remaining tread depth and tyre life, the wheels either rotated or tyres replaced, at no cost to the owner,” he said.

It’s worth noting replacements for original equipment tyres on the Isuzu D-Max, ranging from entry-grade cab-chassis models running on (255/65x17) Dunlop Grandtrek AT25 rubber, up to more premium variants shod with (265/60x18) Bridgestone Dueler H/T tyres, currently retail for well in excess of $400 each. So, the reported problems are not only inconvenient but potentially very expensive.

The MU-X SUV shares the D-Max's front suspension set-up.

And although reports have been gathering pace in recent months the alleged problem is not new, with aftermarket firms like Fulcrum Suspension, headquartered in Brisbane, developing replacement hardware specifically for these Isuzu and Mazda models.

The company says its ‘SuperPro Steering Knuckle’ is designed to combat uneven tyre wear in the current Isuzu D-Max, MU-X and Mazda BT-50, claiming when it’s installed on a standard-height vehicle, the replacement steering knuckle “virtually eliminates bump steer and significantly reduces uneven tyre wear”. 

It’s worth noting many forum commenters have reported no problems over substantial distances, but if you’ve experienced unusually rapid front tyre wear on your D-Max, MU-X or BT-50 tell us about it in the comments below.
