I'm wondering about this.... I would really like to get a more lightweight spare than the 29lb stock one- there's really no reason to have as much wheel & tire *** we have for most of us- I mean, as performance oriented as many of us are w/these cars, a mountain bike wheel would be about enough to get us through an emergency if it would only bolt up- most of us wouldn't drive on the spare for more than a day at the MOST. I usually run w/out my spare, althought the weight removed IS at the wrong end of the car & slightly lower than I'd prefer, but, I've always wondered- does ANYONE know how much drag skinnies weigh? I've seen some in pics that look REALLY SKINNY! Realistically about as narrow as a mountain bike tire- if something that small would work on dragsters.... I'm thinking that if I could find a skinny or something similar that would match our our wheel bolt pattern, I'd be able to keep a spare in the car AND save a good 15lbs or so over the factory one... That would be pretty cool IMO.....

So., anyone......?

Thanks a lot

Uhm, the factory spare already is a lightweight wheel... Not sure if it would be safe to go even smaller. And even though it's a 15" inch it clears the calipers, don't think any other 15" wheel do that.

Well that makes me wonder if it would still clear the calipers if one had a big red brake conversion.

Mark, if you do the big reds in the front you need a 17" wheel. I don't think there are any 16" that are thin enough to fit and 15" is out of the question. 17" is the well understood common wisdom.

Robby, the problem is we have a 5 x 130mm bolt pattern. That is unique and no one else has that pattern. Well, a friend told me that some light trucks made in Brazil for going out into the Amazon had a 5 x 130mm pattern but good luck finding those rims. And they probably weigh about 50 or 75 lbs each to take the hard duty.

Robby

Dan is right & our spare is 16"- For big reds you will need seventeen inch wheels for sure, w/FEW exceptions...

I do NOT consider our spares to be light- HELL @ 29lbs, they are only 12lbs or so lighter than 16" CS front wheels w/tires_ they're heavy little fu**ers... I think they should at least be <20lbs- AGAIN... think about all the drag skinnies...

too bad about the uncommon size Dan, but that's what I was afraid of- thanks....


Stilll- anyone know of any other wheels that might fit?

sweanders

The spare wheel is 15" on the 944, 944S, 944S2, 951, 951S, 928S4, 928GT.

IceShark,

That's what led me to the question. So what does one do if they have big reds other than hope they never get a flat tire on the front? Only thing I can think of is move a rear wheel to the front temporarily but with offsets and widths being different would that even work?

Well a 928GT had big blacks which were the same as big reds...and it has a15" spare

Matt H

And 16" CS wheels will fit over Big Reds/Big Blacks with a little careful grinding on the top of the caliper. PDs will fit if you are not concerned about grinding more of the caliper housing away.

Nope, the GT has the same brakes as the S4, the GTS on the other hand had the big blacks.

Not sure what size the spare wheel on the GTS is, I'll post on the 928 forum and ask.

Tabor

Are you sure? I though only the GTS had big blacks.

Matt H

Drag skinnys are VERY light BUT, the front wheels are not cheap. You could call any number of manufacturers and have them make one for you. I would not be concerned with the width but what you have GROSSLY underestimated is the weight of your behemoth. A drag skinny is not going to have nearly enough tire to hold you car up, they weigh significantly less than a full bodied car. A tempa spare is only able to hold a car because the tire can be inflated to 80 PSI. I am sure you know that a tire's ability to carry weight is in the amount of air pressure it can hold.

Are you sure? B/c I just measured mine- it's sitting in the other room & I had already measured it before- I'm seeing a hair >16.25" from edge to edge w/out question... I know wheel measurements are funny, but.... Just look at how close the distance is b/t Turbo S/928 S4 calipers w/stock Turbo S/S4 rotors- there's ~2mm gap b/t the inner edge of the REGULAR wheel & outer edge- the spare has to overlap the caliper too doesn't it? I know later spares, w/928 GTS, 993TT/996TT, & Boxsters w/optional BR's are larger...

Mark- they would either have to do what you said, OR, buy a later, larger spare....

Matt H- I've heard people say this & I KNOW that some 16" wheels will house BR's, BUT, I don't see HOW that's even remotely possible when looking at my Turbo S- the gap is just SOOOO SMALL.... Also, I didn't really think about teh weight issue- ESPECIALLY since the FWD dragsters use them on the REAR- there is STILL significant weight RE-distribution- would put much more weight on them than using one on the street on a 3150lb 951 in emergency situations I would think- could be wrong- also, there ARE different size skinnies- I've seen some that were litterally, not much wider than mtn bike tires & other's that looked like a slightly thin spare- this is why I was asking if anyone knew if any OTHER type cars had the same wheel bolt pattern- THEN maybe I could find out how much their spares weigh- assuming they are 16" OR 15" if what some are saying is correct, although I just measured mine...I'll have to measure the edge to edge of the CS's I have- they MAY show 17" & it's just WHERE the measurement is taken, BUT, I've seen people list later spares from BR cars as 17" before, although that may be incorrect...

Tabor- haven't seen you around in awhile...

Thanks for all the input everyone...

IceShark

Mark, Ithink you are totally screwed. you can ask Danno who has tried all sorts of different wheels on our cars. I think the conclusion wii be you are in a bad situation if you didn't start out with 17" rims for the big reds/blacks.

I got this reply from the 928-board:
