18, unless the drive and/or trailer axles run 'super singles' on each side, rather than two 275s or 285s on either side.
No.
Depends on the type of trailer you are pulling but for the most yes 8 wheels on the trailer 8 drive tires on the rear of the truck 2 steer tires there you have your 18 wheeler If you re using Super singles ( the single wide tires), then just 4 tires.
A ride on a mower typically has four tires, two on the front and two on the back. It is similar to a four wheeler in the size, but it rides much higher than a four wheeler.
There are many factors that will affect the cost of four wheeler tires. The tire manufacturer, dimension of the tires and whether the vehicle is intended for on or off road use. Generally you can expect to pay anywhere from $140 to $300 for a complete set of tires.
18, hence the name.
