Tire Pressure

Postby Mtflyr » Thu May 18, 2017 5:17 am

Just checking what tire pressure do you guys typically run? I have Kumo 165/80/15 front and 195/80/15 rear and usually go with 20-22 front and 24 rear.

Thanks,

Pete

Peter…that depends on your driving style…these cars oversteer…so if you go into a curving 30 mph type highway off-ramp at 45 mph and lift your foot from the gas pedal, the car will “tuck”…(turn-in perhaps 20 degrees)…if it turns- in 40+ degrees you have too much understeer and need to adjust tire pressures.

For most people… the ideal… is going into that turn with the throttle neutral…(constant) and having the car neither understeer nor oversteer.

If you don’t drive fast…use the lowest tire pressure you can… to take harshness out of the suspension [8D]

Thank ReV

It's Pete. :D I agree with what you've written just trying to see what pressures others typically are running for std road use.

In the area of under and over steer, here's a great chart

Understeer -> the front hits the wall
Oversteer -> the rear hits the wall
Horsepower -> how hard you hit the wall
Torque -> how far the wall moves
Oh sh*t -- It was rocket science!
That's how my brain works. It's not a perfect organ.

Don't forget...neutral steer and the passenger side hits the wall {left hand turns}...gives you a chance to hop out and check out the result :)

Must commit to memory & recall as I steer into the turns...

Love it!


After experimenting w oversteer/understeer, I arrived at:
Tire pressure 22 Front , 24Rear
