Need 14×7 Wheels

I am trying to get my RzR back to 50" and need a wheel with a 6+1 offset. My current wheels are a 5+2 and have pushed me out to 52" which won’t get me through some of the trail restrictors. I recently tried the STI HD3 but when measured the backspacing was less than 5 1/4" so it doesn’t appear they are the 6+1 as advertised.

Does anyone know of any 6+1 wheels, preferably 14×7?
