· Resilient Tyre - Resemble their pneumatic counterpart but are completely manufactured from rubber, no air. Also known as “Puncture Proof” there are differing designs, quality and materials available.
· Press-On Cushion Tyre - Rubber directly vulcanised to a steel band that is subsequently “pressed-on” to a special wheel.
Methods of identifying tyre wear out
· Pneumatic tyres wear out points can be identified in two ways:
§ Top of the 60J line
§ The tread depth indicator
o Pneumatic tyres must have a minimum of 1mm of tread over the centre 75% of tread around its complete circumference.
· Resilient tyres may be used until they are worn to the wear indicator, also known as the 60J line
· Press-On Cushion Tyres may be used until 2/3rds of the original thickness remains or the wear limit is “top of the lettering”.
Smooth (Slick) Industrial Tyres
In several applications (Ports & Docks, Waste Transfer, Glass Recycling, Steel Yards etc.) the presence of a tread pattern results in significant tread cutting or damage. At these sites the use of smooth (slick) tyres has led to substantially improved wear rates (lower costs) without any detriment to safety.
Smooth tyres (on paved surfaces) actually have higher levels of grip, even when water is present (up to 15km/hr). The higher grip is a result of the greater contact surface area (tyre to road).
It is incorrect to assume that tyres with no tread are dangerous or provide less traction, on paved (concrete or asphalt) surfaces.Where loose material is present a treaded pattern tyre will result in better grip than a smooth tyre, due to the tread actually engaging the ground surface.
The time to replace forklift tyres varies between types and operating conditions. One of the biggest risks is that tyres are taken for granted, not being inspected as often or thoroughly as needed for safe operation. The checking of all tyres is an important element of a forklift daily or pre-shift check. Tyre condition is also monitored as part of routine preventive maintenance. Action should be taken to replace damaged or worn tyres without delay.
