Thanks to all. I had seen the chart form innovative balancing too but I don't know the width of my tires. Sorry, I'm a tire size idiot.
It seem like I should use 2oz each accoring to the responses here.
Thanks for your help.
Just did mine on my E-3s....I put 1 oz in front and 2 oz in rear....Purrs like a kitten....
Also got stuck in the rain and those tires handle and brake very well wet!!! o~`o
