My "easily" accessible records only go back to 2011, so I don't have data from earlier than that, but since 2012, I have bought a new set of tires annually for one vehicle or another.
- July 2012 - tires for my truck
- August 2013 - tires for my car
- January 2014 - tires for my horse trailer
- July 2015 - tires for my car (again?!?!)
- March 2016 - tires for my truck (again)
I had my truck's tires rotated in December when I had new brakes installed. At the time, the tires looked great. I drove Speedy to Expo in February and everything felt fine. In Early March, I took both horses to the vet and noticed a worrisome roughness on the way home. It was a sensation I felt the last time my tires needed to be replaced. I checked all eight tires (including the trailer's) and couldn't find anything that looked suspicious.
Since we're heading to Simi Valley this morning for a lesson, a trek of about 125 miles over California's busiest highway, I gave my tires another visual inspection yesterday morning. Thank goodness I did. The problem finally showed up - blown out sidewall.
