Tyres varies in size, color, tread pattern, hardness, and what is contained within the tyre. What is similar is that tyres on MEWPs are the first stabilizing device on MEWPs during operation.
During travel, transportation, and elevation. MEWP tyres play an important part in the MEWP’s stability and how it “terrains” over a ground surface. Today, the vast majority of “RT” MEWPs will be equipped with “polyurethane” filled (foam) or solid tyres. There have been a greater number of MEWPs in the USA that can be fitted with pneumatic tyres; but, as requirements change, US-based MEWPs are increasingly being fitted with solid/foam filled tyres. Solid and foam-filled tyres are puncture-resistant and more resistant to the harm inflicted on MEWP tyres in our business. (However, they are not damage resistant.) When engineers build a MEWP, the weight of a solid or foam tyre is factored into the MEWP’s calculated stability.

The “Load/ply rating,” tyre width, tread width, wall height, and tyre hardness are all important safety concerns for tyre choosing (shore hardness or durometer rating).
A tyre that is too soft can provide a stability threat, while a tyre that is too firm can cause excessive machine vibration and compromise terrainability (traction) It is crucial. Always use the hardness rating of the tyre fill product (the polyurethane product) recommended by the manufacturer. (For example, larger booms and specific scissor lifts will frequently have a tougher foam substance injected into them than smaller booms.) Always use the load/ply rating, as well as the wall height and breadth indicated by the manufacturer.
For enhanced grip, “RT” MEWPs will feature larger tires with more aggressive tread patterns. (However, in some instances, such as “sand” type ground surfaces, a smooth tyre might be a superior choice.) More aggressive tread patterns will likewise experience faster wear and damage rates.
Tyre Types on MEWPs
Smaller Non “RT” MEWPs, such as indoor rated and “DC” or “hybrid” and “Bi-energy” MEWPs, will more frequently have solid “non-marking” tyres fitted, but as the definition of “RT” and non “RT” MEWPs becomes more blurred with more “RT” hybrid and DC MEWPs entering the market (that have the same performance characteristics as e.g. diesel powered MEWPs
MEWPs with solid tyres face the same strict stability requirements, therefore the rubber compound used must meet the manufacturer’s specifications for hardness, wall height, and width.
