I recently purchased a 2012 Tacoma Prerunner Double Cab SR5. I am looking to upgrade my tires/rims to 265/60-18 and add XD Spy Rims. KMC offers 2 rims at 18x9 6x5.5, one with +18 offset/5.46 backspace and one with -12/4.53 respectively. I've been to 4 sites and 2 sites recommend the -12 and 2 sites the +18. Can anyone help me with the correct fitment?
