The front tires on my 16-month old 350Z with 14k mi are badly cupped on the inside and make loud humming noise at low speeds, worse when braking. They've been doing this since 5-6k mi, and it's been getting progressively worse. I was well aware of the front tire fethering issues on the 03-04 models, but figured it is fixed by now, so didn't bother to investigate earlir (Idiot!). Now the Stealership won't do anything for me since I'm out of the 12-month alligment warranty period. According to Nissan this condition is caused by excessive toe-out. Nissan extended the allignment warranty on the 03-04 models to 2 years, and swapped the front tires inside to outside. Some even got new tires, and later $230 or so from a Class action suit settlement. Dealers were required to re-calibrate their alignment machines to new specs. Long story short the problem was never solved, as many later models have the same issues.
Now, the factory Bridgestone Potenza RE050A on my Z are not directional, and assymetrical? as the outside wall clearly states "OUTSIDE". What if I swap them and put the inside cupped part of the tire on the outside in an attempt to even out some of the wear and get few more miles out of them, as Nissan did on the earlier symetrical tires? What's the worse what could happen? Loud noise?-Can't be louder that it allready is. Slippery when wet?-I don't it drive in rain, and drive like a grandma in general. A blow out?-That would be bad. Could they just come off/dismount?
Thx for any help, and sorry for long post
