Thanks…I believe the tires were “warped” from sitting a long time…they fixed themselves after a drive on a warm day. 100%

Ditto! Don Byers 17”.  Best money I ever spent was, new shocks, springs, wheels and tires.  My Pantera since, has ridden like a new car. Perfect.  Because of the front-end floating, I have never been up to 150mph.  ;-)

    A Swedish owner bought new PE wheels several years ago, I believe they were manufactured by Boyd Coddington. They were quite untrue and I would not have been happy if it were my wheels. Not sure if he got the issue sorted or not.
