2006 Chevy Trailblazer EXT LT 4x4 - Will 15s fit?
 

I have a 2006 Chevy Trailblazer EXT LT 4x4. I was originally under the impression that my lug pattern was 6x5.5 so I just bought some rims off Facebook marketplace which are some 31-10.5-15s but apparently my truck is a 6x5 so I ordered 1.25" 32mm 6x5 to 6x 5.5 Wheel Adapters and am currently waiting on them. I just want to know if they are going to clear the brake calipers and rotors. Can anybody help?

I have very little experience with that TB/Envoy platform so I can't directly answer the question, but looking at the rims, they look like they have a very shallow backspace/positive offset. With spacers making that even shallower, your tires will be sticking out a lot. You might be rubbing your fenders pretty bad when turning your wheel.
