Gotta good deal on 20x9 +20 20x10.5 +25 (i know everyone hates 20s,wanted 19s but couldnt turn the deal,theyll do till i can afford 19' Weds,lol). The Z will will be comming out of storage soon, i have a set of BC coilover's waiting to be installed(looking to drop 1',depending on how wheel/tire fit). Would a 255/30 keep everything happy? or would there be a better choice? I would like to run a tallest tire possible without issues or confusing the traction control.

 

255/30 front and 275/30 rear

 

Dropping it 1 inch or morer will likely need rear fenders rolled. Prepare for that
