Not always are US hobby suppliers good.

There was one hobby supplier on E-Bay I will never buy from again. Showed a half dozen tires in 1.5 inch size in the picture. Mentioned nothing of quantities in the description. The only hint was in the item title, something like 35mm lightweight rubber tires in plastic hub (2). I paid around $5 plus several dollars shipping, got only 2 tires. Explanations I got was rude, "anybody who's been in the hobby knows that tires are always packaged in 2's, in essence I should know better. I gave him a marginal rating, he gave me no rating.

Next time I'll buy tires from a China supplier.
