Controversies

Rollover and Firestone Tire controversy

Rollover risk is inherently higher than cars in many truck-based vehicles if they are driven unsafely, as modification for bulky 4 wheel drive hardware requires increases in height to avoid compromising ground clearance (raising the center of gravity), while a short wheelbase

further reduces stability. The previous Bronco II had already been cited by Consumer Reports for rollover tendencies in turns; as with the Explorer, however, it was cleared by the NHTSA as being no more dangerous than any other truck when driven unsafely. With a longer passenger compartment, the Explorer added 600 pounds, but Ford did not deem it necessary to revise the suspension or tires to carry the bigger load. It used the same tires as the Ford Ranger with a relatively low rating for high temperatures. Lowering tire pressure recommendations softened the ride further and improved emergency stability through increased traction, but increased the chances of overheating tires. A 1995 redesign with a new suspension slightly raised the Explorer's center of gravity, but it was called inconsequential by a Ford spokesman. Memos by Ford engineers suggested lowering the engine height, but it would have increased the cost of the new design.

In May 2000, the US National Highway Traffic Safety Administration (NHTSA) contacted Ford and Firestone about a higher than normal incidence of tire failures on Ford Explorers, Mercury Mountaineers, and Mazda Navajos fitted with Firestone tires (later including Ford Ranger and Mazda B-Series pickup trucks). The failures all involved tread separation, in which the outer tread carcass would delaminate and cause a rapid loss of tire pressure. Ford investigated and found that several models of 15 in (381 mm) Firestone tires (ATX, ATX II, and Wilderness AT) had higher failure rates, especially those made at Firestone's Decatur, Illinois plant.
