Widest Trailer Tire Size to Fit on 12 inch Trailer Wheel

Question

Question:

HI - I have a trailer I want to use for yard work and want wider tires so it does not sink in mud as much. The current tires are 4.8x12 and I believe the rims are 4inch wide rims. What is the widest tire I can put on these rims. The trailer is rated for 960 lbs. Thank you
