Going east on I-40 just before Jolley Road, coming from Kingman, before Seligman, i was trapped between an 18 wheeler in front doing 70 mph and also one on the side I hit a pot hole bigger than my tire. My tires are just 1 year old, down to 6lbs in a few seconds. Fortunately I have a real spare. Tire dealer said they will not put the 1 year old tire back on the wheel. Damage was extensive.
Although the I-40 has had alot of kingman to flagstaff road repaving there are still plenty of really bad spots. So be really aware of I-40, especially east bound in AZ...
