Am installing all 4 tires (1 front and 2 rear) Hankook V12 with 245-35-20. The rim is 7.5 therefore am going to have to use spaces at the rear. But I don't want to loose the Tire pressure sensor functionality. How can they be installed? Is there a Youtube video or guide? I want to use OEM tire pressure sensors that are actually on my 18" stock wheels.
