At first, we suspected that Interco had pulled the two steel belts out of the experimental 37x12.50R15, because this kind of conformability is great for a radial, and especially a load-range E casing. We certainly hadn't expected a very cushy ride from these tires, and definitely not at a relatively high 10 psi of inflation pressure on a light vehicle. Kevin ended up running 10 psi for the majority of the test, and only once was there a hint of bounce, while climbing a very steep sandstone wall with moderate tire spin.
