We bought a brand-new pup in May 2009. At FW checkout July 2010 (yes, only 14 months later!) a CM said our tire looked and sounded strange. We looked at it & didn't see anything strange. We drove the 40 miles home, deciding along the way that before summer 2011 when we make a long trip, we'd go ahead & buy new tires to be extra safe. Well that decision changed within the HOUR! We get home, start backing in & see a HUGE bubble on the side of one tire, look & see a 2nd on the other tire. Crawled under to see that there was odd wear pattern to both tires, even though we check tire pressure practically daily when traveling. Needless to say we ended up buying new tires a couple of days later.
This happened after back-to-back years of having blow-outs on our way to FW. We thought we'd beat the curse. lol
