I know the feeling..Example...I was wanting to buy 2 used tires for the Z28....They are the low profile Michelins and hard to find used and in good condition...An ole guy I know in the tire business had 4...I asked him how much for 2 and he said $200..I had asked the price for all 4 and it was $200 so needless to say he would not split the set...I bought all four and have 2 for spares as I run smaller on the front than rear.....But I got what I wanted...at a price...but if I find a set I will let you know..Your wanting the 16" right??
