# What is the operation of dual tires?

## How do dual tires work?

A dual-wheel vehicle, also known as a dually, has four tires instead of just two on the rear axle for greater load capacity and towing capability. Dual wheel trucks are commonly used as work trucks. However, this doesn’t mean that these trucks must look like work trucks.

### Why do trucks have 4 rear tires?

They are designed to tow and haul heavy loads. Having four rear wheels spreads the load, which increases their capacity and reduces road surface stress. This increases truck stability and reduces the impact of a flat tire.

#### What is minimum dual spacing?

The minimum spacing for 8. 25-rim is 13.2”.

How wide is a 11r 22.5 tire?

approximately 11 inches

How is dual spacing measured?

To determine the dual spacing dimension between two disc wheels or demountable tires, add their offsets. For rims add spacer width (see Diagrams). You can subtract the width of one tire from the dual spacing dimension to calculate the clearance between them.

What is the weight of a truck tire?

On average, light truck tires less than 17 inches in diameter weigh around 35 pounds, and semi-truck tires weigh between 105 and 110 pounds. Passenger car tire weighs between 20 and 22 pounds on average.

How heavy is a wheel and tire?

Wheels range in size from 13″ up to 24″ and can weigh anywhere between 7 – 20kg each without a tyre. One 17″ alloy wheel with a tyre weighs on average around 15kg and can usually be packed in a box with dimensions of 50cm x 50cm x 40cm. Tyres can also range widely in size and therefore weight, from 6.5kg up to 20kg.
