I trued the front stock tires on the stock plastic wheels like Marty suggested. Slow and light touch. They are round now but they have differing amounts of tread in patches around the tire. If I followed the regular club practice of truing tires until all of the tread is gone, I might have problems, but so far so good. The read slicks that came in the box are OK, but they lost a little chunk where the grub screw driver passes against the sidewall of the tire.
I’ll have the car long Saturday if you want to check it out.
