1995 Chevrolet Corvette Owner's Manual - Page 201

When your vehicle is being towed, have the ign.ition key off. The steering wheel should be clamped in a straight-ahead position, with a clamping device designed for towing service. Do not use the vehicle's steering column lock for this. The transmission should be in NEUTRAL (N) and the parking brake released. Don't have your vehicle towed on the rear wheels unless you must. If the vehicle must be towed on the rear wheels, don't go more than 35 mph (55 km/h) or farther than 50 miles (80 km) or your transmission will be damaged. Go slow over rough ground, and position one wheel at a time (angled 45 ") if you have to goover curbs and rises. Wheels at the lifted end should be at least 4 inches (100 mm) above the ground. If these limits must be exceeded, then the rear wheels have to be supported on a dolly.
