Carlos, the tires can be a differen't circumfrence even though they are the same size so measuring the rollout of each tire will tell ou this. Also in a 2500 lb car and 2700 lb car i run 6.5 to 7.0 In a 3100lbs car We run 7.5. You need to run as high as pressure as you can w/o spinning or being inconsistent. So i would start out around 7.5 and go up from there. And it does depend on the gauge, but i use two of the 80$ jegs gauges and both of them read exactly the same.
