People Running 09 stock Rays
 

I am currently running the stock size tires on my Rays but as usual the rears are about to be shot while my front tires are still good. Has anybody gone bigger in the rear with out going bigger in the front? I used to run RE-11s 265F and 295R but have changed to Hankooks for the time being. Just wondering how big I can actually go with out changing the front and running into problems.

This, i need to know too, its almost time for new rear tires, id like to know whats the fattest tire size you can go in the back mine is a 13 with the Rays

If you're running the OEM front size 245/40, you can go 285/35 in the rear w/o the same front...that's the Nismo sizes

You can fit 305/30 on the Sport Rays, no problem.

You should know that unless you're modded and/or boosted, you'll notice that your Z will be slower with over size tires.

ah didn't know nismo tires ran bigger in the rear from the factory. I am assuming you meant I can run 285 in the rear.

sprot- 9/10 - 245/275
nismo 9.5/10.5 245/285

i am just about to put on my 3rd set of 265/305 RE-11s on my oem sport rays and i love the setup. gits perfectly and sticks like none other :tiphat:

Ya I loved the RE-11s but they only lasted about 10k miles and my front right blew a belt so I had to move on especially since the price isn't favorable. I have the Hankooks they don't seem bad at all for the price 800 but I haven't had them a year yet and I'm already at 7/32F 3/32R. I'd say I've put about 5-6k miles on them already. So it's still in the air on what I want to do.

you must have got a bad set of RE-11s or your suspension is off lol

i put around 12-14k miles on my RE11 and my rears are at the wear bar at this point. my fronts still 75%+ when i switch to brand new ones around this time every year.

285/35 front and 305/30 rear

Did you look at the Bridgestone S-04? Not as grippy as the RE-11's but, not bad.

I got a set from Tire Rack 265/305 for about $900

Yes, I think I did say 285 on the rear in my op.

On Sport Rays:confused:

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

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

I didn't notice anything different performance wise when I switch to S04 285 on the rear. Or are you talking about people that put 305s on the rear?

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

Aesthetically the wider tires, especially in the rear, look very good.

I was talking about 305's

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:iagree:

If you are leaving your fronts with factory dimensions and 245 width, then I would leave the rears with the same ratio to the front, and go with a 275 in the rear.

If you're willing to increase the front width, then go wider in the rear.

275/305 here

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 :tiphat:

Anyone who thinks 245 fronts are enough, go run your car, Really run the car and then try wider. Trust me, 265 minimum fronts handle incredibly, 285 to me is even better

I need new tires on the front soon. Can I run one of these wider sets without switching the rears at the same time?

Technically yes you can. Would I? No.

Best thing to do is to replace all 4 tires at the same time. Mix matching fronts and rears you may run into different compounds, different wear, different diameters, etc

Also you should want to keep the oem 30-40mm width gap between the front and rears. If it's just a small window of time between getting your fronts then tears you should be fine

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

Anybody see an issue with running 275 35 F and 305 30 R? I have eibach springs if that should affect anything? I've never gone this big before so a little worried about performance.

265/35-305/30 is a better set up.

I'm dropped 1"+ on KW-V3 coil overs

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:icon17:

265/35-305/30, yes, on Sport Pkg. Rays

245/275 RE-11 vs 265/305 RE-11

all the info is on tire rack they weighed them for me lol

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....

I see everybody saying 265 with 305 and I asked about 275 and 305 bc someone is selling them on the forum and I'm just curious what issues I would run into. Has Anybody stayed 245 with 305? Probably no by why not?

do not go 245/305. that gap is way to much the car will handle like shit.

275/305 I know a few who do that and like it.

I do 265 because I think 275 one sport rays is pushing it......then again do is 305 on the rears but oh well lol

All this just makes me confused lol. Hoping I am good just staying with stock sizes?
