No experience with that exact wheel but have run FJC and sequoia alloys that i believe* are very similar in specs.
If you have the shank style lug nuts vs conical seat currently then lugs shouldnt have to be changed. From your avitar it looks like you have a 450 and would be good there.
They likely will sit inboard an inch from OEM 80 wheels and you can chose whether or not to run spacers. I did not run spacers on a similar sequoia wheel but it rubbed the rear frame rail at full stuff, albeit with no bump stop drops.
35/7s fit fine on a 7.5" rim but you may have an issue with big box stores willing to mount them. i had no problems for years then discount tire changed their corp. policies, but would however mount a 315 ?!?
