Replace giant inflated rubber tires with steel air suspension wheels and never buy more tires! Save for more trucks and save the environment! That is smart mining!
At $ 85,000 giant rubber tire price, the current US active haul-truck plus matching wheel-loader inventory of 80,400 giant tires represents a $ 6.63 billion hazardous waste to be paid for by the US mining companies in every year. Instead, at $ 3.25 million giant truck price, the US mines could buy and operate 365 more giant trucks annually, one for every day in a year, year-after-year, including holidays. Think about it, but not head in the sand.
“Win-Win When the Iron Meets the Road”
The OTR all steel ASW is constructed and maintained as the Heavy Equipment (HE) part itself to last as long as the HE lasts (10-20 years) with new treads in every 2-4 years (3 yrs avg depending on use).
Standard ASW sizes: 51″-63″ rim, 109″-157″ OD tire (giant 9′-13′)
Custom ASW sizes: 33″-49″ rim, 72″-108″ OD tire (large 6′-9′)
Special ASW sizes: 15″-25″ rim, 36″-69″ OD tire (small 3′-6′)
All 63”, 57”, 51”, 49”, 45”, 39”, 35”, 33”, 25”, 24, 21”, 20.5”, 20”, 16” and 15” OTR rims are served. Request instant quote on any OTR tire to be replaced by ASW.

Buyer is responsible for ASW maintenance, taxes and shipping. Get quotes on shipping from GACW affiliates. GACW affiliate factories are in Utah, Colorado, Arizona, Saskatchewan and Ontario.
The ASWs are offered with full money back guarantee on performance and standard manufacturing warranties on materials and workmanship, as any equipment parts or sub-assemblies.
The ASW is delivered with its first set of treads at no extra charge and with 5% spare treads crated. Buyer is advised to order more treads in 60 days advance. New treads may be needed in every 2-6 years, depending on use and abuse. Threads cost 10-15% of ASW price, depending on materials and style. The ASW (steel tire with rim) price is set 2-4x the price of the hard duty rubber tire (without rim) it replaces. Size matches the tire to be replaced.
Road gripping bars (treads) are individually replaceable (bolted on). You may resurface six wheels in 2-3 half-an-hour long pit stops, while the truck is refueling and the driver is on lunch brake. No truck downtime for the resurfacing (re-treading), which is needed in about 3 years apart. You may re-tread an ASW during the scheduled truck maintenance times 300 hours apart.

GACW is exclusively licensed to make, sell, have it made and have it sold steel Air Suspension Wheels (ASWs) in Canada, USA and Mexico and to sell sub-licenses of the same for mining vehicles and equipment in the same territories. GAWC represents the IP owner for licensing in the rest of the territories of the world for all wheels and applications. Currently, ASWs are custom made in the USA (predominantly 51″, 57″ and 63″ rim sizes) or imported from South Africa (predominantly 33″, 39″ 45″ and 49″ rim sizes) or from Canada (predominantly 15″, 16″, 20″, 20.5″, 21″, 24″, 25″, 35″ rim sizes).
A CAT 797F 400 tons giant mining truck costs $ 5,000,000 in 2009. It needs six 59/80R63 inflated rubber tires about every 8 months. The tire price of this size (5.4 tons, 4000 mm OD) was $ 42,000-50,000 in 2006. Shortly, during the tire shortage years of 2007-2009, the price was $ 90,000-110,000. Tire prices on the rise, though in some localities, where they still store “crisis price” tires (Chile and Columbia, for instance), this price is reduced to $ 50,000. (See the expensive and cheap rubber tire calculations below.)
If you would pile up in a dense array the 180 rubber tires this giant truck consumes during its 20 years lifetime, it would exactly fill the volume of 3 of these giant trucks. Regulations require onsite tire disposal. The tires do not decompose at least within 100 years.
That is unsustainable. The steel air suspension tire (ASW) offers solution to this problem. It can be recycled as the entire truck itself. It is part of the vehicle. Built and maintained as that. Before its introduction, the mines had to manage the tire cost, inventory, retreading and disposal problems. The ASW alleviate all that problems at great savings, which allows to buy 2-3 more such giant trucks with ASWs. That would boost production capacity three folds. Overall, it can reduce the cost of surface mining by 5% approx.
An ASW costs as low as 2x the major manufacturers’ list price of two rubber tires with rim. Thus, the investment is the cost of the next tire change, due in about eight moths, The ROI is then 100% in the first year when tire is expensive and in the second or third, when it is cheap. Due to notorious tire shortages, that next time tire set of six, typically need to be purchased beforehand and the tires, need to be warehoused onsite. Considering that, replacing the giant rubber tire with ASW is not even hard cash investment, but advanced operational cost or just common sense and environmental responsibility. It is expected to be a welcome game changer in mining. Since steel is not aging, ASWs with steels treads has over 20 years shelf life, though steel in need a few retreading with steel treads. That allows to procure ASWs years ahead of new mine openings.
Our primary market is replacing giant wheels of mining trucks and their wheel loaders with with lifetime air suspension steel wheels. The larger the wheel, the greater is the savings. Yet, GACW makes OTR ASWs of 3′-13’OD sizes serving ant and all heavy equipment.
Only GACW can deliver ASWs in segments for future 500-600 tons trucks. 12′-20′ OD wheels are on the drawing board. Segmented ASWs ship disassembled in standard highway containers or on tarp covered flatbed for field assembly. Canada grants tax brake for most imported “Assembled in Canada” products. The segmented ASW qualifies for such preferential treatment. GACW ships ASWs to all CanaMex transit states, including AriSon (Arizona-Sonora). For other global territories, please inquire.
The steel Air Suspension Wheels (ASWs) complies with all federal and local regulations.
