How many passes on tires or have they been setting? Don't have any radial experience but know some run bias in elimnations and use radials for heads up or class. Basics now you are staging same depth? Car should 60' ie. 1.500 quickest of day 1.509 worst would be good.The more consistent car is in 60' better off you'll be,gotta be able to 60 consistent before you can be consistent the rest of the way.
