Interco's Iroks get wider when mounted and aired up

When our 39.5x13.50-17 Interco Irok bias ply tires showed up, we thought they looked pretty skinny and tall.

Once on the wheels and inflated, the tires ballooned out and were REALLY wide. They also shortened a bit back to their 39.5" diameter. Check out the photo and see the Iroks "Before" and "After". Both of these tires are the same size. Interco's web address is www.intercotire.com.
