Absolute Widest Tire on Stock 19s
 

What is the widest tire I can put on my stock wheels, the sport touring 19s. Thanks in advance!

Interesting question, I've been wanting to ask the same ever since I joined this forum, very glad that someone finally asks!

305 rears been done lots of times

I found this awhile ago when i had the same question and just searched the forum; hope it helps

It's been asked; just a lot of the threads have since been buried and you have to do a little digging to find. I found the above setup in a thread about why you should run 285/325 on NISMO wheels lol

IMNSHO, this site's search is pretty bad. I use one of the web search engines (works with all the major search engines I've tried) and add "site:the370z.com" to my search string. Eg, widest tire site:the370z.com

Unless you dropped in a V8 or are running a turbo, you may have issues getting your NA Z moving, lol. Wider tires are also much heavier than the OEM sizes. Is it just aesthetics you are looking to improve, improved cornering or just bragging privileges with the wider tires?

If memory serves correctly, autoxers were squeezing 295 Hoosiers on the fronts in the stock class a few years back. I'd probably just go with 285's on all 4 corners for a street driven car. The square setup will make the car handle significantly better.

295/30/19 front is possible. Seen it as stated above.
Me personally 285/35 and 305/35 are the biggest I'd use

I'm running 265/305 on my Sport 19's and I've got a few minor performance mods.
You'll definitely notice the performance dip over stock size with the added weight if you're running stock.

I'm going back down to 255/35-295/30 on my next set and putting 20mm spacers back on just to push them out to flush.

I was being sarcastic

Ive seen 325/30/19 on stock 10" wheels.

If I get a second, I will post the pics.

Thats the size i have in my 10.5 Nismo wheels now (like everone else!)

Check page 65 on this thread for 325s on stock wheels.

MarksZ34 has em.

Just don't mind me lol :rolleyes:

I have 345's on the rear. Have no issues with them. :tup: :driving:

This doesn't give the car a "vague" or "floaty" feel in the corners from the sidewalls being bulged? I would think a stiffer sidewall would result in better handling? (honest question)

I get the square part of the equation, I was just thinking the less sidewall bulge the better, so properly sized wheels, or perhaps something narrower than the 285 would be better? Or is the trade off between the contact patch and sidewall stiffness worth it?

315 hoosier slick on the stock sport rears.
I've also run a 295 hoosier slick on the stock sport rears, up front~!

I've run 265/35 and 285/35 at one time, but dropped down to a 255/40 and 275/35 setup, as I much prefer the feel and grip from the non-bulged sidewalls.

I've never had a "vague" feeling on my Z running 18x10 wheels wrapped in 315/30-18 tires on the front. The trick is making sure you get a tire that has a stiff sidewall.

The only time I've had a vague feeling was when I used to run 295/40 tires. Sidewall height, IMHO, has more to do with a vague feeling than pinching a tire on the rim.

I run RE11 285/35/19 front and 325/30/19 rear on Nismo rims. I do not have any vague feeling at all. Stiff sidewall and tire pressure is key.

While I don't argue what you guys feel, having yet to break 15k on a set of tires because of where I live and what I do with the car, I notice sidewall flex and bulge. And I've been there with my old car and know the difference. I much prefer either a square fit for street tires or a slight stretch on higher grip tires.

Mostly, I want to be able to launch the car at the drag strip with little to no spin. I'm considering going with the RE-11s due to opinions of people on here because I have no experience with tire performances with this car. This is the first set of tires that I'm buying. I do plan to be making about 450whp with a nitrous setup in the future but, honestly, will probably have done went through this new set of tires.

If I can stick to stock sizes with the RE-11s and get really good traction, on and off the track at around 320whp, I'd definitely rather go that route. So what would you do in my shoes?

People stating they have flex in the tire, what pressure do you run?

The trick to this is dynamic rear camber on the 370Z. The more you squat the more negative camber the rear gains. If you really cared about drag racing times you'd start with positive camber...

Somewhere in the mid to high 30's. it depends on if I cared to check tire pressure or not, and what tires I was running at the time.
