I could go either way I suppose. If we're actually racing I think it'll be a better test in the heat of battle.

So the 245/45/17 Azenis is nearly the same OD as the 275/40/17 RRs. The 255/40/17 Azenis is wider than the 245 (obviously), should be better for wear and heat. The 255 Azenis is 0.6" smaller in OD (25.6" OD for the RR, 25" for the 255 Azenis). The price difference for the 255/245 Azenis is less than $1 on tire rack. These tires are in the $150 range - tires at this price would substantially change my ability to show up to races and prepare the car.
