This is going to sound stupid, but your tires are awesome! What did you paint/weather them with?
Thanks, I painted the tires in a mixture of panzer aces light rubber 305 and dark rubber 306. I just mixed the colours until, I like the shade. I then put several thin washes on them in layers until I was happy with the look. I mixed several thin washes from various earth tone pigments thinned with odorless turpintine, to get a mixture of shades
