Help me choose rear tire Size s13 coupe

[nismolvr]

Just want to get some ideas on what would perform and also look better on my rear tires . I finally got the wheels i wanted thy are BNR32 GTR rims 16x8 +30 . Im using 225 60 all around now (Stock for R32GTR).Im set on keeping the fronts that size. I want to use a bigger tire with more surface contact in rear. I dont plan to drift ,im interested in getting more grip. This is my daily driver. I dont plan on rolling fenders , my suspension for now is Eibach sportline springs on tockyko shocks.I eventually get coilovers and lower a slight bit. here are some pictures

Get wider rims...225 is pretty much squared on an 8j (8" is roughly equal to 205mm). Running wider tires wont necessarily be better when you have so much flex on the sidewall. Also, just because 225/60-16 is stock for a skyline, doesnt mean its stock for an S-chassis. Kick it down to 225/55-16 to match with stock sizing.

not that im a coupe, but, i run 225 45 17 on work vsxx with a half inch offset on the rear. And without a widebody rear quarter or rolling my fender thats about it anyway, Im slightly out of square with these parts and oem sheet metal front and rear. While the launch is spectacular, corner handling with a z32 vlsd is sloppy. I run nexen N3000 directional traction tires.
