if i had a choice i would go filled tires.
for me though, i tend to choose a higher "ply" rating for tires. and regardless of type of tire, will put a tube in. i have way to many thorn trees and thorned bushes, were the needles are like nails. and having more rubber that a nail or thorn has to go through before i get a leak or a flat. can make me a happier camper.
if this was for construction equipment, and going to different job sites, it might be a different story, but if tractor going to be primarily at the homestead. filled tires for sure.
having weight can be just as important as HP and traction. and the 3 of them are all linked together.
to many times i have been in situations were i need more weight and not have it. vs situations were i had to much weight. and in that, if the ground is to wet / mushy and making ruts. then it is to wet to begin with to even be on the tractor. the exception of FEL and heeping loads of dirt in the bucket. having rear weight on tractor can be the best. doesn't matter on type of weight as long as you have weight in the rear. (tires, 3pt hitch, or other)
==================
as far as tire changes go. i will pay the $50 to $100 dollar service fee. for tire folks to come out and do everything.
i don't have to take wheel off and put it back on (time saved, dragging out and putting tools away), cleaning up any buckets or barrels for fluid in tires.
i don't waste time, gas, muscles hauling a tire to and from some tire place.
service person most likely has rounded edge flat bars, and air compressor driven bead popper. along with soap or lubrication to getting tire on and off easier.
service person should have an air gun or like, that will have enough torque to tighten all the nuts up to specs.
for the 555c TLB, what are they 28 x 14? just tire alone with no tube or rim on. weighs to much than what i am willing to deal with alone. more so trying to lift it, and pry it around.
ya call around for tire service, including up to 1.5 hours away. there is a huge price differences between places. and different brands of tires, tubes, and service fees.
