Tire Flip Help

Ok so it’s going to be my first time doing the tire flip. I’m using this as a training tool and not competing. I’m 5’9" 180 lbs, 405 deadlift, 425 squat (both raw) and was wondering what size/weight tire I should probably start out on? I want something that will challenge me but not kill me (I’ll get a bigger one to kill me after I get form down).

500lbs should be a go.

400-600 pounds

alright thanks
