Our '87 C4 wants new tires for spring. OK, not an unreasonable request but...
... wait for it ...
... apparently it's such a rare car and such a rare tire size that aside from expensive drag radials, hoosier rain tires or Toyo RA-1s for a grand a set, there are no DOT-legal tires available at the moment. The only regular two tires in that size (255/50/16) that are normal high performance tires are Falken ZE-512s and BFGoodrich gForce Sports, both listed as back order with no delivery date anywhere.
So out of four cars we have over here, we have precisely one that is working unconditionally - my wife's Cherokee. My CJ has just disabled itself again and I'm getting tired of that game, the C4 has tires down to the wear markers at the front and the Celica is a project that's quite some time away from road legal.
Happy Bunny, not me...
