I put new Goodyears on my 1978 Newell. I put 3 golf balls in each tire. It had Centra-matics

on it when I bought it but they were kinda rusty so my theory was that the golf balls would perform similarly. Those tires are nearing their "time out" and have run smooth. (Much to the chagrin of my tire dealer friend!) I just had 8 new Michelins installed on my 1993 Newell. I had them install new valve stems with filters and put the bags of balance powder in them. It shook like crazy for the first 10 miles til the bags broke and then smoothed right out. I was a little dubious about the balance powder and still not totally "sold" but so far so good.
