Does the Center Hole Matter on a Trailer Wheel and can 16 Inch Wheels be Replaced with 15 Inch

Updated 05/05/2015 | Published 05/04/2015

Question:

I recently bought a stock trailer that had 16 inch rims made for tube tires. I want to replace the rims with rims that are made for tubeless tires. The axles are 7k axles and there are two axles. My question is about the necessity to go back with 16 inch tires or if I could go to 15 inch tires. Also, what is the center hole diameter on the rim I am asking about? Thank you in advance.

First, the center (pilot) hole on Taskmaster wheel # TA73VR is 4-1/4 inches. This will only matter if A) the wheels secure to the hubs with wheel bolts rather than lug nuts or B) if the pilot hole is too small. It can be larger just not smaller if it attaches with lug nuts.

You can go to a smaller tire and wheel size provided the combined capacity of all of the tires is high enough for the gross trailer weight. I have included some helpful links on tires and wheels for you.
