UPDATE ****
Ok so, i'm going to sell these and have bought 16 x 8 black steel rims with a 0 offset and a set of Insa Dakar Turbo tyres (BFG M/T COPY) in 265 75 16.
Thanks for the help guys, i'll post some pics. I liked the idea of the aggressive offset but can't get away with it without the arch (fender) extensions in this country!!
