22" wheels are very heavy and your suspension was not built for 22" wheels. This can wear the suspension at a much higher rate than the stock wheels.
You may have to align the vehicle more often now with aftermarket wheels. Shocks/struts would be very rare to cause abnormal tire wear. You may want to have the alignment shop check your wheel bearings and control arms to ensure they are not worn. This could cause the wheel to lean slightly inward or, in your case it seems, outward which would result in quicker tire tread wear.
