There was recently a thread about which generation Maximas were the fastest, and someone posted a very informative guide about power/weight ratio and tire weight. It showed that 15" tires were actually ideal for acceleration because they weighed less. I am wondering what tire size would be the best for handling as opposed to acceleration.

 

The bigger the wheel, the smaller the flex which would give you more responsive steering. But at the same rate, a bigger (heavier) wheel would add to your unsprung weight which would make the suspension less able to do it's job.

 

8 in wide or bigger rims n micheling pilot sport tires which are really expensive. usually 17 in is 7 or 7.5 n 18 is 8in wide. 19 i believe is 8.5 but remember that you can spend a lot of money n get really light 18 in rims n those michelin pilot sports. volk racing rims are expensive but really light. they're about $1500 - $2500 depending on which ones u get. also the michelin pilot sport can run about $150-$200 a tire. so if you have money, you can have both acceleration n handling
