*if you're worried about understeer, go w/ a 295 R-comp up front  |
Adding more rubber up front will give more grip, but only to a point. There are other factors to consider when you get to those extreme sizes, including the unsprung weight impact on acceleration, braking, turn in, and your spring/damper settings, ride quality (transmission of NVH), and the certainty of your having to install a power steering cooler if you run that much tire up front on a road course car. On a twisty track you will almost certainly start boiling your PS fluid with tires at 275 treadwidth and above, when driven hard on the Z and G.
