Stock Sports Tire Size
 

I know this topic has been beat to death and believe me I did do a lot of searching and research before I posted on here.

Basically I need to get tires. I decided to go with the Bridgestone S-04's. My question is,

For the fronts should I go with
1. 255/40/19
2. 265/35/19

My backs are gonna be 285/35/19 (still can't decide if I should go 305/30/19)

Car is stock height with no spacers.

Thanks!

I went with a 255/40/19 front and a 305/30/19 rear, if that helps...The 305 rears just looks right, 285's are still too small IMO.

I'm also thinking about going 305/30 on the rears. Just wasn't sure if it would fit. I know the RE-11's fit but will the S-04's fit?

Should, tire size is tire size, with the 305/30/19 there is still a lot of room, if I had wider wheels a 345 would fit no problem.

Remember every lb of rotational mass is equivalent to 10 pounds carried in the car

I'll need tires in a few months and was thinking 265/35/19 and 285/35/19 to keep the stagger close and keep the beefy look with the S04s. Im running stock size PSS right now but they seem to run wide compared to others and already looked beefy enough. I have 20 mm spacers all around. I don't think a 305 is really necessary on stock sport wheels, especially if you want to stray away from understeer with such a big stagger.

I have seen stock stock sport wheels with 305's, stock height and no spacers and it looks a little silly having a squished tire on there when its still sunk in the wheel well so much.

For a 305 the wheel should be at least 11" our rear sport wheels i believe is only 10". As stated above its like a big bellied guy with a waist of 41 trying to fit on a 36' jeans.

Well smart guy how does the size of my butt equates for every lbs of non rotational mass carried in my car? Lol

It equates to an extra passenger? Just throwing out a guess!!! Lol :ughdance:

I'm just trying to help the guy out. Our car is all about power to weight ratio. Nimble like Spider-Man yet strong. We're non hulk that why we can move around better at autoX. The thing is...do we really NEED wider tires to put the 300ish WHP down? Or is stock size better quality tires better than going wider plus adding more weight. This is why people go with 2 piece rotors to save rotational mass weight isn't it?

In addition to stock sizes, I've run 255/285, 265/285, and 265/305 all on the stock sport rims. You're not going to notice a bit of difference unless you are driving the car hard at an auto-x or at the track. And at that level, the type of tire you are using makes way more difference than the sizing. Hell, even street driving the tire is going to make a more noticeable difference than a minimal change in sizing. I usually have my tire picked out but pick sizing based on my budget at the time they need replacement. If tracking or auto-x it's all about performance, so I would want to evaluate various combinations myself in those environments.

yah, do the nismo sizes... 245/40/19 and 285/35/19.

Bigger is better, i'm putting these on my Z next!!

I am running a 305 on a 10.5" wheel and I think it looks and performs great.

No that would be the stretched look. Putting 305s on a 10" rim is like parachute pants :happydance: :icon17:

I run 305's on the stock sport wheels, looks fine to me...

Lot's of good info in here!

I haven't gotten to the point of needing to replace my OEM Potenza's yet but I'll def be checking this thread when I do.

I know bud you are definitely correct! Why cant you take a joke Mr. Flujoke?:tup:

The 305 would definitely work and perform as it should with the sports wheels. No doubt.
But if your not considering the way it should look flush near the wheel fender then you should be good.

I would possibly use a spacer but that would be my personal preference.

Either way your good with the 305.

I have 20mm spacers and want to keep close to stock stagger. It will also depend on what brand tire you buy as they all measure differently. (i.e. michelin 305 runs noticeably wider than say a Bridgestone 305). I have stock size PSS right now and they look great, but are too expensive for what I'm using them for. Anybody care to show more pictures of their tire combos and sizes on stock sports?

Thank you kind sir. Sorry go ahead tell me a joke :)

Looks good. Never going back to stock tires though! haha

Ya I had BFG sport comp 2's on my roadster and traded em in for PSS to discount bc I wasn't satisfied. I loved those but I'm gonna try some RE-11's on the next go probably this time next year? Idk
