Here is a link to a site that i use constantly to compare tire sizes for projects. It allows you to compare tire sizes and gives suggestions for other tire sizes and available tires by clicking a button below the speedometer error chart.

Seeing a lot of tire questions lately, been covered countless times on here.

Neutral offset or 4.5" backspace would be a start on an 8" rim. If that checks out i would focus on correcting the front geometry (camber curve) so the front tires "tuck" during suspension travel and turning instead of leaning out.

Our stage 1, 2 and Ultimate front end kits do this in various stages of degrees.
