I can't figure it out. My car that makes around 900rwhp sat for a few months, and then I drove it on a road trip but needed new tires. So while I was out of town I had some new BFG DR's installed. I've been through a dozen sets of these over the years w/never a problem. So I get on the highway and do a hard pull and my car starts walking all over the road nearly uncontrollably! I can't figure it out. It feels like a drag car does when you're on a full slick and it just floats around. PSI is 28lbs on both rear tires which is where I always keep them to help w/traction. What are some steps I can take to figure my problem out? Thanks--Andy
