Spoke with Miller Tire today. The 6.00x21 tires that were used on the high crops can be made. I told them that I felt there was a demand for them. I have someone who has a tire to send to have it duplicated. Just need to show there is a demand for them. They said the minimum that can be made is 200. They said if I can gather a list of people to have 100 spoken for they would have them made. I'm sure there are many high crops out there needing 21" front tires. So if you would be willing to buy some of them please let me know (PM, call, text, email, letter, whatever) and I'll put a list to gather of who and how many they want to buy. They said the tires would be around $260-275 each. I know that seems like a lot and it is for front tires but for 99% of the people who buy these they will likely be the last tires you ever buy for the front of your high crops. Also, this might be the last chance anyone will ever be able to buy the correct tires. I believe these tires were used on D-15, D-17, D-19, WD, WD45, UC high crops. I may have missed one. If you would have interest in speaking for some of these tires let me know and I'll put the list together.
