Great question, Tom! The best way to figure out which AirSkirts tire wedges you need is to measure the space between the bases of your adjacent tires before ordering. These wedges help fill the open spaces above or below where the tires come closest together, keeping cold air from slipping through the wheel area and beneath your RV.

The 22 inch wedges part # AS69VR are designed for wider gaps, but many RVs only need the smaller 17 inch wedges, part # AS49VR. If your RV has enclosed wheel wells, the wheel well may already block the upper gap, meaning you may only need a wedge below the tires so that is something to check out.

What type of RV do you have, and have you had a chance to measure the space between the bases of your adjacent tires?
