Bigger rear wheels and tyres

[James]

Have a tractor with 480/70 28 fronts. Currently have 580 on rear. To go to 710 or 800 on rear obviously I'd need new wheels but could this be done without changing the fronts?

Yes if new tyres have same rolling circumference as old. Or at least very close to

580/70r38 on rear? 710/60r38 or 800/65r32 will match up

Yes.
Jb had a set of 710 plus wheels but they're sold

800s would be more common but wide wheels of any size don't sit around for long
