In normal use, what are the chances of something happening to the front suspension, WITHOUT the driver knowing about it, that would cause weird/irregular wear patterns on the tires?
Heck, of all the vehicles that I've owned in the last 49 years, only two of them came up with funny wear patterns on the front tires. One was a Ford pickup with a split front beam axle,.....which I learned had a history of doing this. I did NOT take it to have the front-end aligned. The other was a Chevelle that my drunk friend borrowed, and 'fessed up much later, that he had hit something pretty hard. I didn't take it to get the front-end aligned either. I jacked it up and checked it for damage. I found a bent steering link, took it off and straighten it, and drove it for about 2 more years.
Of the 6 motorhomes that I've owned, I have never had the front-ends aligned. I've checked for toe-in/toe-out myself, using a scriber and a measuring tape.
I always tell people that if they detect a weird wear pattern on a front tire, just take it to several tire shops and get an opinion from the oldest/most experienced tire person there. Do not let them do any work until you've gotten second opinions on all first opinions. Then, do some Google research, and get educated on the subject.
Sure, it's too late for the OP,.....but at least I got it off my chest....:B
