Question about stretched tire setups
 

I have a two part question. I'm currently running a staggered 19X9.5 +22 F, 19X10.5 +12 R setup, with 265/35/19 and 295/30/19 tires, respectively. I'd like to move to more of a stretched tire setup. Nothing crazy, probably more mild. I'll post some pictures (attached) below of a side profile of my current setup and then two photos of more of the look I'm going for, which was from a previous forum member (Calvin, who many of you know, he had a great build thread). My first question is: based on my current setup, what tire size(s) should I go to for a mild stretch, like the yellow one in the photos? My second questions is more in regards to performance. I've read that with a stretched tire setup you lose some performance handling and are not able to be as aggressive, say if you're running mountain roads. But is that case for ALL stretched tire setups, even something mild? I don't really plan to do much Mountain touring or auto X'ing, but I'd like to be able to take some fast turns and hit a mountain road every once in a while. Is there really that much performance lost? Sorry for the long post. Appreciate the info.

We may be arguing semantics here but I wouldn't call what's going on with the yellow z mild at all. I'm pretty conservative with my taste in tires and feel that even the stock sport set-up is too narrow for the wheels provided, so take what I say with a grain of salt.

As for performance, so long as we are talking mild not extreme stretching, its more about preference than simply better over worse.

A slight stretch will give the tread a more flat profile for more steering response, but can make the break away characteristics more abrupt. Essentially one second you will have grip, the next second you don't.

A pinched tire will have more progressive break away characteristics. Its more forgiving, but you lose a bit of steering response.

:iagree:

Thanks for the quick responses. So if I was going for more of a look like Calvin had in his yellow 370, based on my current wheel specs any idea on what tire size I should be looking at? 275 rear, 245 front? I realize this is opinion, just trying to get a close idea.

I'd say the rear has to be somewhere 225-245 range... maybe less
I had 275/35 on my Advan's and they were not nearly as stretched

Wow. Yeah you're setup doesn't look stretched at all really so yeah, probably going to have to go quite a bit narrower. Thanks for the feedback. Your car is sick, by the way. Great setup.

Your wheels are not wide or aggressive enough to pull off the stretched look correctly

That yellow Z has a very aggressive and wide wheel with a low offset which will make stretching both necessary and functional (to run that low)

Your wheels will just look like you're on a thin tire if you try to stretch as you have it today.

Before anything you need to lower your ride. Those wheels don't fit right.

:facepalm:

Z starts to become cheap and this is the stupid type of thread that pops up. lovely.

stretched tires are fuckin stupid. also you lose any hopes of performance and make the car unsafe.

Ill fitting tires are dangerous. Period.

People have been stretching tire on the Z34 since 2009, because of the backlash and ignorance on this forum they just choose not to post their setups publicly

To each their own, I like the look when done properly but would never do it myself

sooooo they have been hiding in shame. makes sense. :bowrofl:

there's no "proper" way to stretch tires. its just an unsafe way to look like a douche.

Not going to argue with you, it's pointless because you have shown time and time again how little you know about this topic and I don't care to defend stretching tires beyond my previous statement

Strecthing is not dangerous when done correctly. The Cyber Evo team won the GTA for numerous years on slightly stretched tires (look it up)

I get that but the point is that no one that I've battled on here was stretching for performance reason as the cyber evo team did.

these people are stretching for a stupid look, to clear fenders because they have terrible offset wheels and want to lower to where the car can't perform at all, or because they think a unsafe non performing sports car is cool.....but it's not.

I know plenty on the topic so let's just move along.

The problem I think is the misconception of thinking you can have the look and keep the performance. You can't have both. If you want to go with the pizza cutter size tires on fairly wide wheels you are going to be sacrificing quite a bit of grip. I mean the whole concept is like shooting yourself in the foot. If you want grip, or more of it, then get wider tires. When you start limiting your tire size to the opposite side of the spectrum then you limit the functionality of the vehicle itself. To each their own. If you want to stretch go right ahead but please just limp back and forth to the car show. Otherwise I might suggest getting two sets of wheels. One for show and one for go. :twocents:
