I was looking at buying some rims of an unknown size. They are wearing 235/35Z R19 (front) and 275/30Z R19 (rear). I feel like the fronts might be big enough but the rears are probably only 9.5 or 10 inch wide wheels, correct? This is just a guess. So I'd like an educated option on the size of the wheels and a guess as to if I can run these on my 996 widebody Turbo, possibly using spacers? Thanks for any advice

 

Don't do it

Get the right sizing to begin with

 

sorry, but that is some crazy kind of straight from hunger kind of stuff. don't do it. "educated option"? advice probably won't help. you need wheels designed to fit a 911 porsche turbo.

 

Thanks guys, this is kinda what I figured, it was just a good deal on some really nice wheels and a chance to help a forum member with a sale. I was just hoping it was an easy fix with some spacers. ll take your advice and just get some properly sized wheels

 

porsche makes a 17mm set that is designed for just that issue. Here they are:

I have a set that pushed my stock wheels out flush with the fender using 295's. With your 275's it will probably make them look like stock 295 fitment. I would not use the 21's they sell. Way to extreme. I'll see if I can find any pics of mine. I sold the wheels off last year o don't have any current pics.

 

Spacers can fix an offset problem - they cannot fix a too narrow wheel problem. Big difference.

 

spacers can bring a wheel designed for a CS out to look like a turbo wheel on a wide body, which is why porsche sells those spacers, in order to fit narrower wheels on the wider bodies if you have to do it. Not saying it's perfect, but that is what it was meant to do. That's why porsche also sells a 21mm spacer as well

 

I might be mistaken, but I think you may be confusing some wheel terminology.

Porsche makes a 17mm or 21mm spacer (the 21 is advertised as "extreme") for fitting narrow-body wheels on a wide-body variant. The spacer corrects the offset, but thats not the same as your assertion above (bolded, my emphasis). For example, to fit a narrow-body GT3 rear wheel on a turbo, you'd need those spacers. That doesn't mean the wheel is too narrow (it isn't - it's 11 inches wide, just like a turbo), it just means the offsets are wrong for the wheel to properly fit the wide-bodied cars.

Addressing the OP's question of "can spacers fix a narrow wheel" - I, and others apparently, would say "no." Wheel width is what it is, regardless of any spacer(s) used, and so too-narrow is too-narrow - the wheel doesn't magically get wider when adding a spacer. OTOH, if you have a properly sized wheel (i.e. correct rim diameter and width), but the offsets are incorrect for the car - spacers might be able to fix the issue.

Said simply, spacers fix/address wheel offset issues - they do not fix/address wheel width issues.

 

I agree that a spacer does not fix a narrow wheel. The question was whether he can run a 10 inch rim on a wide body with spacers and the answer to that is yes, and the 17mm spacers will do just that. It may not look perfect, but it will work. For example, if he wanted to use those wheels as his winter wheels with blizaks the 17mm spacers would give him a close enough look with 275's on 10 inch wheels. Is it preferable, no, but it will work. If you are saying it will not work, then we disagree.

 

Glad we can agree on that.

That was not the question - the question is in the thread title, followed up with the post below:

He doesn't know what size the wheels are from the info posted, front or rear, other than that they're 19" diameter. He doesn't even specify what kind of car they came off of - given the tire fitments, they could be 19" HREs off of a current sports sedan (M3/C63/RS4) for all we know.


Far be it for me to speculate s4gotten's intended purpose, but I doubt he'd be looking to buy some really nice 19" wheels to throw Blizzak's on as his winter set.

We don't have enough info to even know if these mystery wheels would fit at all, much less work as intended for a 996 WB application. Since you appear unequivocally convinced that these wheels mentioned by s4gotten would bolt right up to a 996 Turbo, no problem, as long as a spacer is used... yes, we disagree.

 

to which i would only add: mystery wheels don't belong on porsche turbo's.

i love this bar.

 

Porsche specs 265 rear tires for the winter shoes for a 996 Turbo, which would require a 10" wide wheel as opposed to the 11" stock size. I speculate this was done because wider snow tires didn't exist at the time the car was produced as opposed to the narrower size being spec'ed because of the propensity for people to run narrower snow tires than summer tires. In order for a 10" rear wheel with the same offset as a NB car to look okay on a WB car, you'd definitely want to run some spacers.

As for whether to run such narrow tires, that would be a terrible idea. The Turbo is already in need of as much rubber as possible in the rear, and many of us find the 295 tire already not adequate to the job. Run what's designed for the car.

 

wow i'm loving all the response to my question. Let me provide some additional parameters to this argument and Id like to hear a couple more opinions. These are indeed mystery wheels, the only info available being the tire size, which I've provided, and they supposedly fit and were being run on a NB 996 carrera, not oem or factory wheels though. I know spacers dont make the wheel wider but can I safely run these on my WB Turbo? I was possibly going to use these with snow tires actually (funny you should mention) they are being offered for next to nothing, the tires on them are worth way more than the price for 4 rims and tires. Also can anyone guess the wheel width by the tire size? Keep the conversation goin folks. Thanks!

 

I could throw these on before road trips so I dont waste the wide, expensive UHP summers on my stock Turbo twists

 

also I know that the turbo wants as much meat as possible but I would just keep the drama down when running these. If it will drive badly or be very unsafe I would just as soon skip. Its just some nice 19s for a steal and I want to know if its worth it.
