Kioti lk 3054

[2012doublet]

Ok I’m new at this so don’t laugh if I’m doing it wrong. I have my dads old kioti lk 3054 and I’m restoring it I noticed one of the front wheels is cracked and I searched feverishly to no avail for a replacement it’s a 14” 6on 4.75 pattern. It has a number on it 105402 14x5 bkt but even that comes up nothing I’d also like to put some fatter tires on it but didn’t know if they would balloon out on the narrow wheels. Please help. Any pointers would be much appreated the tires on it are 14 x 7 and I was wanting to go to a 14 x 8.5 and on the rear it’s a 24 x 11.1 and I found some 24 x 13. I know I’ll have to check the heights so I don’t mess with the ratio but those r1 skinny tires just sink as soon as I get in the mud so I was wanting more floatation it would be nice to change out all the wheels for the r4 industrial lug but that’d be way to expensive if I could even find some
