Dyno Tire Pressure? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Question, what tire pressure should I run on a dyno machine? I am running factor GY F1 tires right now on my car. I want to get the most accurate dyno reading with out the tires slipping. Its cold right now in Houston area and my tires will not hook up very well right now. Reason I am asking, is I had a 2014 Mustang GT with some goodies on it and the car was chirping through the gears on the dyno machine. I don't think I was getting the most accurate data with the tires chirping. Thanks

We apply VHT to our dyno drum when necessary. Low tire pressures aren't preferable when doing a dyno pull to redline in fourth gear

Question, why don't you do the dyno pull in 4th gear?

Good catch... this is many months late, but I just saw your reply. We do most pulls in fourth fear to capture the 1:1 ratio. This was a typo on my side.
