Agreed, but with every other California Wheels kit they have the extra wheels included.
I did buy one and after reading the box over I wasn't holding my breath.
Not nearly as disappointing as the reissue of the '56 DelRay which was advertised as a 2n1 in the original Revell literature, but when it came out was a direct re-pop of the California Wheels kit which has all of the stock parts except the "snap-in" white wall tires. Still I can't believe those tires and the small runner of white-wall inserts cost THAT much that they couldn't include them. But then again I actually like the rims that are part of the California Wheels kit anyway once I looked them over.
