On Sport Rays

Personally, I'd go one of 3 ways...

245/40-285/35
255/35-295/30
265/35-305/30

Yes, I autocross on 285 square and enjoy it because I can lift off oversteer... If it was daily, I'd do the 285/305

Ok, I understand the 285 x 4, I'm just unfamiliar with people running 285/305 on the street.

On a stock Z, that's a lot of added weight & drag.

I agree, maybe a tad bigger on rear but the stock fronts are plenty wide, extra weight, PS issues

I run 265/305

265 tires weigh the exact same as 245

the 305 tire is only 3lbs heavier than the 275. so you only gain 6lbs total at the rear axle.

reallllllllllllllly small gain to make you not want more grip.

I can make a chipotle stop and take a mean dump to lose a few lbs to counter the tire weight

When you went with bigger tires was 265 40 and 305 35? I'm assuming on stock rays? Also what tires did you weigh?

Ok, maybe it's not the extra weight that's the issue, but certainly there's increased drag with the wider tires.

All I know is the car feels slower to me. Not massively but, noticeably...at least to me. Maybe my perception has to do with the fact that the Hancook V12's I was running (at oem size) were so bald that the new, fatter tires & new tread make me think it's slower

well step one is to throw away V12's they're trash even when brand new lol

all tires will feel a little squishy and whatnot new based on lots of meat and compound on them. unless you buy something that only comes with 6/32" from new like a R888 etc....
