I would like to think that I wouldn’t hold a bad sample against a manufacturer, but I had two new cars come with Firestone tires and didn’t have good results. The first time was in 1978 with a new,Oldsmobile. Cutlass. It came with Firestone 721 radials. These tires developed a bad reputation and in my experience the reputation was deserved. What made it worse is that the local dealer for Firestone tires wouldn’t give me an adjustment when one tire had a manufacturing defect. He said I had to drive to a town 30 miles away and work with a Firestone store there. The dealer would,however, sell me some new tires. I was so disgusted that I drove down the street to Quality Farm and Fleet and bought four new tires under the Duralon house.brand. These tires did give me satisfactory service. Years later, I bought a 2011 Toyota Sienna and it came with Firestone tires. Even though I rotated the tires on schedule and kept them properly inflated, they were worn our at 35,000 miles. These Firestone tires didn’t wear as well as a pair of inexpensive Sumatomo tires that I bought at NTB for the front wheels of the Uplander I owned. The reason I bought these Sumatoma tires was that a fellow musician had lost his job as a full time director of music at a church that cut staff, so he took a job selling tires at NTB and he was paid on commission. Fortunately, my friend did find another music job and the NTB store closed. The location was good and when I saw the building being remodeled, I was hoping for a 5 Guys Hamburger so I,wouldn’t have to wait until we make the 350 mile trip to see our son whose town does have a 5 Guys. However the NTB location became a matress store.
