I have a mildly worked six in a XR wagon, i am running on the eighth, car weighs 1430 kg, my street wheels are 15x8 welds prostars with 255/60/15’s, i also have a pair of 185/14’s on my original steelies. I was going to fit these up when i drop the pipe, to me they have less roll out and should help it off the line by being smaller, wheels spin will not be an issue, not enough HP for that, the 14’s i figure should get me to the finish line quicker but i wondered as to what pressure i should run. I am changing the wheels at the track as car is to low to drive normally with the 14’s on, track only wheels.
