I recently purchased new set of 35 x 12.5 for my truck with a set of 1/2 wheel spacers. Are there any cons to running these? I have a slight vibration around 55 mph but didnt know if it was from the spacers or tires were not balance right.

 

those slide on spacers that thick may cause you problems. your wheel studs are not long enough for anything over 1/4. and yes they could be causing the vibration

 

yea if they arn't hub centric they could mess some stuff up
