Low condition tire has less friction on the road.
A critical lack of condition or pressure can also make the tire burst.
— In-game description

A tire is an item forming an integral part of a vehicle, and can be found in three different variants, valu-tire, regular tire and performance tire. It is critical that they are well maintained and replaced once they degrade.

Usage

Installing

A tire is fitted onto the vehicle with the use of a jack and lug wrench, on top of the suspension and brakes. Therefore, the tire must first be removed to access either of these parts. This can be done at mechanics 1 without possibility of damage.

It is not possible to mix classes of car parts. For example, a standard class tire cannot be fitted onto a sport class vehicle. It is possible, however, to mix types of tires, as long as they are the same class. For example, a standard class vehicle can have performance tires in the front and regular tires in the back, so long as they are all standard class parts. This is not recommended, however, as it can severely alter the driving dynamics of the vehicle.

Driving

The tires are used to transmit the power of the car onto the surface in order for it to move. Better tires have more grip, allowing faster acceleration and tighter and faster turns, and will wear out slower. The best to worst tires are performance, regular, and valu.

It is possible to drive a vehicle with only three tires, but the handling characteristics will be severely compromised.

Condition

Tire condition will constantly decrease while the vehicle is moving, and will decrease at a greater rate when driving off-road, with the exception of heavy duty tires, which degrade slower off-road than on-road. Tires can not be repaired, meaning the only source of new tires is either looting them from various places, or salvaging them from other vehicles. Tires with low condition have far less grip on the road and are more prone to bursting.

The below table shows the chance of losing condition for each tire when off-road and on road.

Tier Vehicle type Road Off-road
Valu Standard 0.04 0.5
Heavy-Duty 0.04 0.35
Sport 0.08 0.5
Regular Standard 0.03 0.4
Heavy-Duty 0.03 0.25
Sport 0.05 0.4
Performance Standard 0.02 0.35
Heavy-Duty 0.02 0.15
Sport 0.02 0.35

Tires also have a pressure stat that must be maintained with the use of a tire pump. Having low pressure will be more prone to bursting or falling off the vehicle.

Distribution

Tires can be found in sheds, garages, mechanic shops, and in trunks of vehicles. Note that tires found inside trunks are always flat and must be pumped up in order to be used.
