I track six, two-day, events per year. Two days ago, I hit the leading end of an apex berm and ruined a tire. My intention was to replace all four tires after this event, so no problem there. I am going to get Michelin Sport 4S replacements. However there are two ways I can go on my 20 inch Porsche rims.
1. Stock sized tires (235/35/20 and 265/35/20) OR slightly oversized tires (245/35/20 and 285/35/20)
If i get the stock sizes, I can get N spec tires. If I buy the oversized tires, I can still get the 4S tires but they won't be N spec.
Questions: 1. Will slightly oversized tires make enough grip difference to give up the N spec rating?
2. Will slightly oversized tires mess with my traction control nannies? I know that my speedo will be slightly off.
