That makes sense. I was told that they were 5+2 but I wanted to confirm for sure.
What size tires are you running?
I run 27x11x14s on the back and 27x9x14s on the front. Still using the stock wheels with 1.5" spacers although before I bought the tires I had the same 11s and 9s on my Brute in a 26" all on a 5+3 wheel and they worked fine...except the 9s on an 8" wheel isn't the best choice. Should have been a 7".
There were the test tires and wheels I put on the Z.

And this was the test video I did way back in 2015.
