unusual tire wear pattern
Crawled under to fix a rattle and was alarmed to find severe wear on the out-most edge tread of the steer tires on the passenger side. The Bridgestone tires have 5 ribs (4 grooves). The edge tread on the inside of the tire had slightly (1/32) more wear than the three center ribs.
The inner and outer ribs being worn suggests under inflation but the tires have always been over inflated if anything, The actual measured weight on each tire is less than the lowest weight on the tire chart.but these tires have always been inflated more than the lowest number on the chart.
The fact that the outer rib is very heavily worn suggests a camber issue but they’re on a straight axle so there’s no adjustment except bending the axle,
On the other (driver’s) side, both edge treads had only slightly (less than 1/32) more wear than the three center ribs.
Sliding my hand across the surface of the passenger side tire.gave strong evidence of excessive toe-in (grabbed when sliding outward). However, Sliding my hand across the surface of the left steer tire.gave evidence of excessive toe-out (grabbed when sliding outward).
The only cause I can dream up is that we drove it through very heavy head and side winds for 2 full days (maybe 900 miles) going out west last year. That was 4,000 miles ago.
Any ideas regarding the cause of this very strange wear pattern on the right steer tire?
