is it ok if i put 36 13.50 iroks on 15x8. it would be for mainly offroad use only. ive heard if i put them on 8 inch rims i could air them down to about 10 or 12 psi so they would be less likely to pop of the bead than if they were on 10 inch rims. ive gotten mixed answers for a couple people and i dont no. i dont want to go out and spend the money on rims and it not work. they are on mt classic 2s right now but i really dont want to use those offroad cause i dont want to ruin them.
