On the contrary, most guys use 26", because they're cheap and plentiful. Very often these tires aren't even frontrunners, but cheap radials. This negates the benefits of frontrunners - lower mass, less rolling resistance (growth at the top end for even less rolling resistance at speed), and weight transfer on launch. Some of these "donuts" may not have adequate load ratings.
For a "stock" suspension car using 28" slicks, I think 27" frontrunners are ideal. Goodyear makes 'em. You just need to ask, as they very often don't appear in catalogs. They're a little more, but they fit like a glove.
Taller tires, like 28", rub, depending upon the specifics of your set-up.
I think we're on the same page Strike. I'm currently running 26" Goodyear frontrunners that actually measure 25.5". Not only do they look a little small vs. my 28" slicks but I'm also not getting enough weight transfer. I'm looking at going to a taller frontrunner to help get the front end up a little. I was thinking of the M/T 28" (actually measures 27.5") but if Goodyear has a 27" I might check that out as well. Thanks for the tip.
