MAXAM MS406 45/65R45 loader tyre: fitment and cost-per-hour notes for mines
Reviewed by Tom Sullivan
First reported on International Mining – News
30 Second Briefing
MAXAM Tire has added a 45/65R45 size to its MS406 E4/L4 off-the-road tyre line, targeting heavy loader applications in mining and large quarry operations. The MS406 design uses a deep tread pattern and reinforced casing to handle high load cycles and abrasive conditions, aiming to extend service life and reduce unplanned downtime on large wheel loaders. For mine operators, the new size broadens fitment options on 45-inch rims, supporting tyre standardisation across mixed fleets and tighter cost-per-hour control.
Technical Brief
- MS406 E4/L4 classification targets combined earthmover/loader duty cycles on hard, abrasive underfoot conditions.
- Deep, cut-resistant tread rubber is engineered for repeated loading in rock-face and muckpile work.
- Reinforced casing construction is intended to manage high load cycles and thermal build-up on long shifts.
- Tread design focuses on resisting chunking and tearing from sharp blasted rock in large quarries.
- Casing robustness supports multiple retread lives, improving lifecycle cost versus single-life loader tyres.
- Pattern and void ratio are tuned to maintain traction on compacted haul roads and loading floors.
- Design intent is to reduce unscheduled tyre changes at face loaders, limiting production stoppages.
- Loader-focused OTR tyre development like MS406 aligns with mines pushing higher instantaneous bucket payloads.
Our Take
MAXAM Tire’s move into the 45/65R45 loader segment adds to a relatively small subset of our 2265 tag-matched ‘Product’ pieces that focus on heavy mobile equipment rather than processing or fixed-plant upgrades, signalling continued OEM competition around load-and-haul productivity.
For mine operators like Boliden, which our coverage shows are pushing ‘green fleets’ across copper, nickel and zinc operations, newer 45/65R45 E4/L4 options could support lower rolling resistance and better tyre life, complementing investments in low-emission trucks and loaders.
With 1219 Mining stories in our database, tyre-specific developments such as this MS406 size extension remain a niche but operationally important theme, often surfacing where sites are constrained by haul fleet availability or are trying to stretch loader productivity without major capex on new machines.
