Stock porsche 997 tires - will they fit?
 

Hey guys,

I'm not terribly knowledgable about tires and fitment on our cars (or any other car for that matter) and know that a lot of questions like this are asked everyday.

I have a chance to purchase a set of 235/35/19 and 295/30/19 re050A for $600.

I'm thinking it's a solid deal but don't know if these tire sizes actually fit our cars or if they'll cause any problems. I know our stock sizes have a higher sidewall on the front and the tires are wider (245/40/19). Will stretching the tire to get it on the rim have any negative results with handling, fitment, etc?

Thanks in advance.

Stretching will adversely affect everything...

But you REALLY aren't stretching much... So you should be ok. You're just going to have less sidewall (your speed will be a little off too)

The rears are slighlty undersized. the fronts are severely undersized. Your ABS/VDC and what not will be going crazy though. You could use the rears but I definitely would not use the fronts.

Don't do it. Not even considering the sidewall differences, the car will handle like crap with a 235/295 stagger. If anything the Z needs more front tire. The last thing you want to do is take that away while adding more to the rear.

Thats what I run, and have zero problems. Alot of cars, ie: the one they came off have no problems either. I got mine used for $200 V12's with right around 1k or less on them.

I can't imagine running that much stagger on this car.

The reason the Porsches pull them off so well is because of their weight distribution. They need that stagger for stability. The Z on the other hand is heavily front biased.

Again I have felt no differences in it. First hand experience. I can post current pics if needed.

Hell, I have 305's on mine rear, No issues to comment on. I had continentals on it before. They did grip better but that was mainly the tire compound difference. Watch eBay after a nice weekend and you can find good deals from rich guys that want fresh tires for their next track day..

Is your car daily or it is being tracked and/or autocrossed?

On another note, the shorter sidewall, plus a slightly more stretch fronts, will make for even bigger wheel gap and make it look a little weird

If you plan on "lowering" the car, i'd run and try that setup.

If NOT, i would look for a bigger front tire because it will look awkward with no drop.

/thread :)

You can't track or autox the V12s, at least not effectively anyway....

Are v12s no good for track? Even if they were properly fitting tires? That was going to be my next choice of tires since I'm poor (relatively). I'm hesitant to fork over the dough for PSSs

You will overheat them within laps, they grip marginally better than fuel economy tires. They are just average everything with a great price tag

^ What he said. If you drive your car at all spirited you should noticed some MAJOR understeer, which to me outweighs the fact that the car will also look funny with such a small profile up front. Yes that is a great deal, but for me it would definitely still not be worth it. Fork out the extra cash and get some proper sized tires (265/35/19f and 285/35/19r is supposed to be a excellent setup for our cars).

The wear of a summer tire with the grip of an all-season

They look straight to me for DD'ing. I have felt no real difference in them for DDing and driving them spirtedly. I am sure a different story for track purposes, even that model tire would be a no go, but I dont believe he is asking about tracking purposes, but of any really noticable side affects, which I can 100% say is none for just BS'in on the street.

Sorry I have to disagree...

if all one cares is to DD related performance of the car, why even bother to get a Z, especially a sports pkg one? Base brakes and open diff will work just fine....

For reference, couple other daily related things Nissan thought were "fine" but really weren't

-lack of oil cooler
-steering locks that fails through no fault of owners

Just because it works doesn't mean it's a good suggestion.

I am still have snow tires on the car even though it is spring, it still works.

That dash looks very familiar lol

That it does. So funny people on here. Blah Blah Blah about this performance tire and that performance tire. From what I have seen on here maybe 10% actually have even taken their car to the track, split that in half and those are the few that actually go weekly.

Those tire the OP asked about will be more than adaquate for anything that can be done safely on the street. Those sizes will allow you to top your car ;)

Thanks for all the info guys. I really appreciate it. I've decided not to go with the cheap tires and just save for an extra two weeks for some proper tires. I had intended to use them at the track but not for time attack. The reason I was looking for cheapy tires was because I'm going to be burning through them at the drift track.

You don't necessarily need to go to the track to feel the negative affects the tire combo will have. One spirited corner and you'll probably notice the insane understeer right away.

So you are going to save for an extra 2 weeks only to burn through them in a few sessions??? Go to a used tire place and buy every 19" 265-305 that you can get your hands on with 30-35 profile for like $30 a peice. And also a pair of some crap 19x10.5's. I am starting to question if you are even serious about learning to drift or came up with this idea on a cocktail napkin at some bar drinking with some buddies.

This thread is all full of win here! From a guy wanting to spend extra money for track purpose tire to only burn them off, to people making assumptions by saying you will "probably" feel the understeer, without even driving on them. Most people on here I can safely say have never even come close on the street to hitting the grip thresholds of the factory crap tires. But yet drop serious coinage on PSS or re-11's only to cruise around town and maybe if the car is lucky some spirited driving.

SPECIALIZE: Buy a spare set of wheels for your drift tires. Then you can have a street set of wheels/tires as well as your own drifting wheels/tires. Swap out wheels when you arrive at an event or practice course. Buy cheap rear tires for your early drifting days. In fact, most tire shops have a discard pile of tires that they will let you go sort through for free rubber. You're going to be burning them up; match your budget to your available effort (hey, it's easier to to buy new tires and pay someone to mount them for you, after all) and time.

TIP: Smaller wheels and tires are easier to spin, requiring less horsepower (read: less money/investment). Less hp means less wear. Sure, we've all seen someone brag about their tuned 1,000 hp Supra Turbo that can spin 20" rims filled with Pirelli P-Zeros, but what Mr. Tuner isn't telling you is that the money spent to bump up that engine isn't going to last very long...that motor may only last 4,000 miles before it needs a full $$ rebuild. Most of the tuner kids learn the above the hard way, and when they do finally realize it, they end up leaving their tuned car in the garage for most of its life because they don't want to pay to fix anything again. That turns them from drivers into museum attendants. Welcome to living online instead of out on the track. They can brag about their car, and maybe even *trailer* it to car shows, but they can't/won't drive it any longer.

Good luck drifting with a huge stagger.

If you were looking to drift them that would have been fine, I wouldn't run such a narrow front as your permanent setup though
