Hi... yes I mean it. Because as you know it... two tires wear out 50% faster than that other two...so by rotating every year, you balance out the wear and this you get longer tire life before you replace them.
It also depends on what tire you buy too... I personally always buy tires that have high wear rating yet maintain the ZR (or other above 149MPH ratings).. Bridgestone RE750 is my favorite 3-seasons only tires (will last about 45,000 miles properly rotated)... I always use snow tires for winter.
Whichever tire you buy... the higher treadwear rating, the longer it will last you. I suggest you do some research at Tirerack before you go buy new tires...
If you have abnormal wear... like center wear... or two side wear... or even one sided wear, you must have an alignment done... or your new tires will wear out very fast.
I suggest people do their alignment every two years unless you see some abnormal tire wear. Every year is just too often and time consuming... plus it cost you more than the tires itself.
I personally have not had my car aligned for 4 years now... and tires wear perfectly. I know I am overdue but unless I see something seriously wrong... then I will do it.
