Yes, they are extremely expensive tires, out of my price range too. When I first called to get a price I was emailed a quote, it was exactly $2957.58 for 6 tires mounted on rims including shipping, that works out to almost $4000 Canadian lol. I was lucky and found a barely used(like brand new) set from a 6x6World member for an amazing price. I jumped on them and drove a 1000 mile round trip to go pick them up lol. I'm sure your oil burner will have no issue turning those tires and nobody needs an excuse for a turbo!
