There are alot of tires posted in the photo ads on ytmag.com and if you want new tires go to a local tire shop (not a chain store) they should be able to get them.
There is a place the JD EQUIPMENT uses. Almost every used tractor gets new tires put on it, and the get the used ones. It'll come to me in the next day or two
Set down before you ask a price on 20.8-38's. Like oliverpuller said. ytmag.com usually has some tires for sale on there. Other than that a local place is the best place.
I have not priced a set of 20.8's but i did price a set of 18.4-34 SAT firestones and they were $1550. I figure the 20.8's will be close to 2000 now. Of course there are cheaper brands to go with if you just need a good farm tire.
That is dang good prices, cheapest radial we stock regularly in 16.9 r28 is 800 for a BKT... we used to stock alliance 324 and firestone sat-II in bias for 400 each
