I have a 430 case yesterday I blew a front tire and damaged the wheel beyond repair, I am wondering if there is a car wheel that will directly replace the front wheels.
I have a 580B which has (IIRC) 10 lug front wheels, found a couple of pix of the 430 online and both the tractor version and the TLB version have six lug fronts. I don't know of a CAR with more than five.
You might find a truck or heavy trailer wheel that fits, but since those tractors had no front brakes, you may run into OTHER compatibility problems.
First thing you'll need is dimensions of your bolt pattern - since these are 6 lug, you just measure (probably on the GOOD wheel) center to center distance of two bolts OPPOSITE each other - this is your "circle" distance. so if you measure 5 inches, you would ask for a wheel with "6 on 5".
Beyond that, you'll need to know the width of the rim and its diameter.
If your tractor has a loader on it, I would NOT recommend a lower priced, lower load limit tire - you'll only end up back where you are now
