OK, i forgot my password, so for those few people that have come into contact with me, the old name was "E". Anyways, I have had 3 tires replaced by my dealer b/c of bubbles. I noticed, the other day however that the new tires, while the same dimensions, have a 91 sidewall rating instead of the stock 95. Needless to say im not happy, but I wanted to ask you guys what, if anything this meant to the cars health, and performance, before I yell at my dealer and have him fix the problem. I know that I should have picked up on this ASAP when it happened but it never crossed my mind that they would do this. Lastly, why would the dealer do this, to save money, or are the 95 rated tires hard to come by, what in gods name would give them idea to do this, or are they just stupid. Any help is very much appreciated, as always. It should be noted that at the moment I have one tire with 95 and 3 with 91, in case that makes a difference.
