Monster Truck Tyre

The Monster Truck tyre has been known as flotation tires, as they were originally designed so that their volume of air means the farming equipment that uses them can float slightly on wet, muddy fields instead of sinking into the mud and getting stuck.

Despite their size and rigidity, due to the weight of the trucks, the tires tend to flex a considerable amount. It’s generally only for a split second, but sometimes the tires flex so much that the rims of the wheels make contact with the ground. To combat this, some drivers over-inflate the tires. This, however, makes them more at risk for tire blowouts.

Tread patterns

One of the most distinct elements of a monster truck tire is the tread pattern tire. The agricultural tires that are the basis of monster truck tires usually have a simple tread of deep, sharp V-shaped or alternating stripes (depending on the manufacturer) intended to provide grip in mud or loose soil without getting clogged with earth.

For monster truck use, this tread is modified by the team, usually by removal of some rubber through “cutting”. Tire cutting is done though for more than just stylistic reasons, though, as different tire treads result in different performance. Tire cutting is also done to accommodate the driver’s driving skills and the conditions in which the truck will be driven. The most common modification made is to reduce the overall tread depth, which reduces weight and increases flexibility, and to round the edge of the tread near the sidewall, which makes it easier for drivers to upright the truck if they land on the edge of the tire after a jump. Cutting each individual tire takes approximately 50 consecutive hours.

Obsessed runs its tires backwards.

A majority of trucks have their tires mounted with tire stripes pointing downwards. On occasion, trucks may run some, or all tires facing the opposite direction. This may be for stylistic reasons, or because the backwards-facing tire is an opposite side replacement for a flat.
