2007 Honda Fit - Tire Wear/Alignment Issues

No, this is not a Sport model - it’s the basic Fit.
I admit I don’t check my tire pressure regularly. Based on everyone’s comments, it seems I should definitely add that to my To Do list!!
I don’t know what the original tires or the second set of tires were, but the last set were Sumitomo Touring LS-T 175/65R14.
According to what I’ve found online, the Sumitomo Touring LS-T tires have a wear rating of 640.
Yes, the tires have been rotated as specified by the Honda maintenance schedule.
No, the first time it was the dealer and since then it’s been my mechanic.
