Thanks Jimmy I did not know that. I read elsewhere after your post that the disco steel wheels are 7 inch wide while the natos are 6.5 so basically the outside of the rim sits out about the same either way. I’ll probably run the D1 Steels anyway since the natos are for another build. Even after 25 yrs of rovers I still learn a lot from you all. ThanksIncorrect. The D1 steel spare is marked 33mm and NATO/Wolf are 20.6mm
