SPI Wheel Systems
A LEADING AGRICULTURAL, INDUSTRIAL, AND OFF-HIGHWAY WHEEL MANUFACTURER
SPI manufactures over 10 different types of fully customisable wheels, including:
1. AGRICULTURAL
Agricultural tyres and wheels are what most tractors are fitted with from the factory. These are standard wheels that come on the tractor from the manufacturer. In Australia, most farmers change from standard wheels to something more customised depending on their application and choice of tyres.
Different types of agricultural tyres include:
Bias construction tyres
-
-
-
- Bias tyres have cord piles that are arranged running diagonally from the bead across the tyre. Layers overlap forming a crisscross pattern. This design features excellent sidewall resistance, puncture resistance and high load capacity.
-
-
Radial construction tyres
-
-
-
- Radial tyres have cord piles that are arranged running radially from bead to bead around the tyre. Sidewall and tread have independent functional features providing more flexibility, great performance, durability, and fuel economy.
-
-
High flex tyres (IF and VF)
-
-
-
- SOIL-IMPROVING TECHNOLOGY
- IF/VF solutions widen your tyre’s contact area on the ground reducing soil compaction. This technology results in enhanced traction, less slippage, and increased soil consumption leading to overall increased yields.
-
-
IF Tyres stands for Increased Flexion
-
-
-
- IF Tyres can carry 20% more load than standard tyres at the same air pressure, or they can carry the same load as the standard tyres with 20% less air pressure.
-
-
VF Tyres stands for Very High Flexion
-
-
-
- VF tyres can carry 40% more load than standard tyres at the same air pressure, or they can carry the same load as the standard tyres with 40% less air pressure.

Benefits of IF & VF tyres
-
-
-
- Reduced soil compaction
- Less operating costs
- Optimized operating hours
- More load capacity
- Maximum performance
- Ensured Comfort
-
-
There are many variables to consider when deciding on what agricultural tyres you need:
-
-
-
- Load being carried
- Required speed – farm-to-farm transport
- Ground clearance required
- What crop/s are being grown
- Specified row spacing
- Need for adjustability with different crops and row widths
-

2. DUALS & WHEEL SPACERS
Clip-on duals are a simple clamp system that easily mounts a second wheel to the inner wheel of your tractor, creating a dual wheel. The two wheels can then work together sharing the load between them, rather than just one wheel taking the load like standard. The clamps for the clip-on duals are made from the highest quality forge materials, and are very durable and strong, making it easy and safe to mount and dismount the clip-on dual system as often as required. Clip-on duals are a great solution for farmers that need to use the same tractor for multiple tasks.
Clip-on duals are used for their versatility. They are great for when you need more stability and traction out in the field while their larger footprint reduces soil compaction, protecting crops and increasing yields. They work exceptionally well in hilly terrain, handling slopes with more grip, thanks to their increased ground contact area. They also have more flotation properties making them safer in wet conditions, while saving fuel.
SPI cotton-reel spacer duals are designed by our experienced engineering team to precisely suit your application. A cotton reel is a wheel spacer or hub adapter that bolts directly between the two wheels to widen your track setting to suit your desired width. They are easy to fit and provide the benefits of duals with a customised track setting.
3. FLOTATION
The ideal flotation wheel equipment doesn’t come standard with new machines. However, SPI’s extensive knowledge and expertise can provide custom solutions to meet your specific requirements, minimise soil compaction and damage, or increase machine performance in wet conditions.
The obvious value of flotation tyres and wheels is the increased traction from the wider structure of the tyre. Farmers typically look for flotation tyres in the wet seasons. However, their high traction doesn’t mean flotation tyres are only for wet conditions. Flotation tyres have a special trend pattern that allows for very heavy loads to be carried at lower pressures, whilst ensuring reduced soil compaction and preventing damage to crops.
The more flotation properties your tyres have, the better they are going to be for your soil and crops. As you would understand, the more footprint the tyre has, the more power your tractor will be able to convert to the ground. This saves you valuable fuel and lowers compaction, protecting the soil and roots of your crops.
4. FORESTRY
Forestry wheels and tyres are designed for the most extreme and harsh conditions that will ensure forestry machines achieve the maximum guaranteed performance. Specifically engineered to provide the most durable and highest quality solution.
SPI Forestry wheels are reinforced to ensure they will be able to sustain the extremely harsh terrain that demands them. Forestry tyres need to have a high puncture resistance as well as a longer tyre life-cycle to be able to operate in the most difficult forest conditions. The heavy-duty service of forestry machinery requires excellent traction and maximum protection against cuts and chips to the tires. Forestry tyres are usually a steel-belted bias construction, with a robust log design for optimal performance.
5. MULTI-USE & INDUSTRIAL
SPI can supply a variety of solutions to suit any industrial application, ranging from nonaggressive grasslands and tarmac applications, wider lugs for hobby farmers to hard-wearing reinforced wheels and tyres for severe conditions such as constructions sites, roadside maintenance, and mining applications
6. OFF-ROAD TRUCK & SPECIAL APPLICATION
SPI stocks a range of off-road-truck solutions, “SPI SUPER SINGLES” super single tyres and wheels are designed to improve the performance of trucks in off-road applications. Making it easier and safer for drivers in rough and boggy terrain.
7. OTR & EARTHMOVER
SPI continues to strengthen our compact construction and earthmover wheel and tyre range with multi-purpose construction tyres, and radial and bias ply tyre solutions for earthmoving applications. We offer a huge range of earthmover wheels and tyres for all types of machines – including graders, loaders, articulated dump trucks and rigid dump trucks working in applications such as surface mining, quarry, construction, undergrounding mining and road construction equipment. your off-road tyre needs.
