Despite my previous post on this thread...
I often say that tractors are for "tractoring" (verb), mowers are for mowing.
Tractors can mow, most mowers can't "tractor" (-:
Mowing tractors aren't suitable for manicuring Home and Garden grade lawns.
Tractors are kinda Swiss army knives, when we use them as mowers, loaders, back hoes or forklifts we have to accept the compromises (at least, I have learned to).
If I was a "lawns guy" I would have a zero turn mower and keep all tractors OFF the bowling green quality lawn - wouldn't even allow croquet because of the divots, etc.
I am NOT a "lawn guy", so R4 marks across the "yard" don't matter that much to me.
So, if "tractoring" needs include FEL use I would make SURE that the front tires can take the max load that the loader can lift (times something for being cantilevered out there).
A pair of front wheels with R4s might not be THAT expensive and they are fairly light and easy to change, so swapping just the fronts for loader work may not be a HUGE hassle - add to that taking the loader OFF for lawn work and your Swiss Army Knife could work out very well.
Not as well as separate ZTR & dedicated tractor, but well enough.
