Big O Tire — 85737 Cracked sidwall, wont warranty, because of uneven wear Oro Valley Arizona!!. I had previously had 2 tires that I bought a t Big o replaced because the sidewall was cracking all the way around. One of the tires they replaced it with is starting to do the same thing. I went in and had them check it out and they said it still had just enough tread life to be replaced. They ordered the tire and said come back the next day. when I brought it in and dropped it off they called me 30 min. later and said they cant warranty it because of the wear to the inside of the tire. and that they had a sale on tires now so it would save me 17.00 off a new tire. Ever since Jarrod left as store manager this shop has gone downhill. I will now be doing business at Discount Tire on Magee and Oracle.
