You can buy axle cradles for your bottle jack. They help support the axle.

If you place a jack under the saddle bolts with a cradle, either purchased or made from wooden cribbing you will be oK. The other way is to roll the trailer up onto a pile of blocks. For example crib under the front curb side wheel. As the wheel rides up the cribbing it will assume all the trailer weight on that side and the rear curb side wheel will come off the ground. Can only do one side at a time. Something like the Andersen Rapid jack is ideal - works for my trailer.

I always jack under the U bolts when I only have to lift one wheel at a time to change a tire. Anything more involved than that and I will take it to my trailer guy.

How to jack up a grand design RV


1. Use emergency flares when near a road or highway.

2. Block the wheels on the opposite side from the tire you wish to change to prevent accidental movement.

3. Position a hydraulic jack on the frame close to the spring hanger. (never attempt to use a stabilizer jack to lift the RV.)

4. Raise the trailer until the tire clears the ground.

5. Set a jack stand under the frame just to the rear of the tire being changed.

6. Follow the wheel Nut Torque and Wheel Re-installation instructions provided below.

Tire Ply Composition & Materials

Tires are constructed from multiple layers of rubber-coated

fabric. Each of these layers is called a ply. In general, the higher

the number of plies in a tire, the more weight it can support.

• Tire manufacturers must report all materials used in the

composition of their tires, (ie., steel, nylon, polyester, etc.)

Spare Tire

The spare tire is used if a trailer tire is damaged, flat, or loses

air pressure. The spare tire/wheel may differ from the original

equipment, and is intended for temporary use ONLY.

The spare tire is secured below your RV. Locate the 1" access

hole in the skirt metal on the door-side of your RV, approximately

even with the spare tire. See Photo, Left.

• Insert the crank handle extension.

• Turn counter-clockwise to lower the spare tire.

• Turn clockwise to raise the spare tire.

Tire Changing Basics

• Hydraulic Jack & Jack Stands are customer supplied.

1. See page 65, Roadside Emergency.

2. Block the wheels on the opposite side from the tire you

wish to change. This will prevent accidental movement.

3. Loosen the wheel lugs BEFORE raising the RV.

4. Place a Hydraulic Jack on the frame close to the spring

hanger. Raise the trailer until the tire clears the ground

NEVER attempt to use a stabilizer jack to lift the RV.

5. Set up a Jack Stand under the frame just to the rear

of the tire being changed, then change your tire.

6. Follow the Wheel Nut Torque and Wheel Installation

instructions provided on the Next Page.
