I'm getting near the mid 4's with Crusaders on a radial, have been 1.14 60'. Don't think 1.0's are a problem, I do believe I'm to the point were a canister shock would be a big improvement. Have them front and back, almost always get off the line, if I have trouble it's usually a few feet out.
On a 28x10.5 with my previous car we went 1.19 60' on a no prep with Vikings. That was at 3,393 lbs on the starting line at a track that is known to seep water up through it in the middle of a drought lol
