This topic was somwhat discussed in another thread, I thought it warranted it's own thread. I currently have Falken FK452's on my y33. One rear tire already has separated inside the sidewall and it has been replaced. Now my other rear tire outer sidewall looks like it has some bumps developing (like the belt is starting to separate like the last one, inside had long bubbles on sidewall). Recently it seems this issue seems to be popping up on the forums numerous times, specifically the Falken FK452 tire. I have a feeling it may be the tires. If you have had the same problem please chime in. If you have different tires, please provide the Manufacturer and Tire Name and tell your experiences (good/bad) with those tires.
