I would appreciate information of the dangers of running tires with hair line cracks (dryrot) in the sidewall areas on passenger vehicles. I took two 4 year old Uniroyal Larado's of my 5th wheel because they had developed cracks in the sidewalls and my rig weighs about 14,000 lbs. They have about 90% of the tread left. Would it be safe to run them on my 1 ton pickup? They are the same size as what I run on the front of my truck. How does dryrot effect the integrity of the tire? Thanks for any input. thanson
