I don't think I said that clearly. I know many use fat tires and skinny wheels because of class rules, but if you look in the unlimited classes many choose to use tires a few sizes smaller than what they could actully fit in order to get the rounded sidewall like on the Bozz car, but in both front and rear. A lot of AE86 guys do this, and it looks like they're running lowrider tires on wide race wheels. This makes the whole car breakaway smoothly and predictably, like you said. I was trying to point out that it's not always the best idea to try to stuff the widest possible tire under the car unless you're running wide wheels to go with it. A good rule of thumb for tread width I've found is (RIM WIDTH + 1) X 25, so for a 7.5" wheel the ideal width would be 212.5, which you would round to a 215. For a 245, ideally he would want an 8.5" or 9.0" wheel, which I don't think he wants to do, so a 215 would be best for predictable handling.
