About 6 months ago we took my daughters '03 Volvo S60 to a national chain and purchased new tires for her. They installed 205/65/R15 tires. Since that time, I have noticed that her tires seem low an awful lot of the time and one of us (usually me) has to inflate them. A month ago she went on a trip and one of the tires blew. She took it to the chain and had it replaced with the same tire. Last week she told me that she was driving to Nashville, and I asked her to go to the local TD and have the tires checked before driving it for 6 hours each way. They said that they found a small hole and patched it, but other than that the tires were OK. On the way home from Nashville, another one of the tires blew! No TD was close so the tow truck took her to a local shop. They told her that TD had installed the wrong tires, and installed one (1) 195/65/R15 to replace the blown tire. Now that I have done a little research, I see that the last gentlemen seems to be correct. OEM is 195/65/R15. But here is my question: would that tire size difference in any way explain the problems that she has been having? Obviously, something is not right, but I cannot figure out what it might be… Now I’m either going to have to change 3 tires that are marginally taller (about .5 inch, I think), or one tire. Which tire shop should I be angry with? Thoughts?
