High speed touring in a powerful sports coupe has all kinds of risks associated with it, the least of which is a flat tire I think. You know, it happens, deal with it. You can't expect a car company to cover all your bases in every contigency. All vehicles make design compromises of one sort or another. Run flats is also a compromise that is no less distasteful than no spare, either in terms of ride or expense. Ask a Lexus SC430 owner, who is the very antithesis of a Porsche owner anyway.

I currently have a Jag XKR which has a standard spare. Since I have a couple of older Porsches I was thinking of a new 997 to replace the Jag next year. Since I do take the car on extended trips I really want a spare. I am now going to check out the SL500. Although I haven't driven a car with run flats I find it hard to believe that the Corvette and 645i BMW give up much in handling/ride .

Replying to: pathdoc (Oct 06, 2004 9:40 am) Not having a spare won't keep me from buying a car, but until runflats get a lot better, I'll avoid any car that has them (which is getting harder to do). regards, kyfdx |

A doughnut tire I could accept. It is interesting that my older Porsches (70 914-6& 78 911 SC targa both have full sized tires. Progress?

Progress has many definitions.  There should be a doughnut, at the minimum. Other premier sports cars have managed this accomplishment (Porsche 911 included) for many decades without adversely affecting handling or performance. As for the argument that sports cars come with risk, well, that may be the case if we were talking about a stripped Lotus Elise here. But we're not, we're talking about the 911 which is as chock full of features and luxury amenities as many a top-tier sports car today. This makes the omission more notable. They should include a standard satallite phone

It's these big fat tires they are putting on cars today. they certainly wouldn't fit in an old 911 either, so what can you do?

I'd have to look the car over to say anything more about it, but it could be that a doughnut is actually impossible with the current design. In other words, the spare tire was consciously designed out from the get-go. Maybe you could lie it flat in there and lock it with a center bolt but ....goodbye trunk space. It's kind of a non-issue for me. I haven't had a flat tire in ten years. (uh-oh, I shouldn't have said that...damn!)

The 928 solution with the inflatable mini tire and air compressor that plugs into the cigarette lighter was a decent solution---but they still had to make a well in the trunk floor, and also one for the battery, which means they had to move the exhaust system around, which means they had to put a big butt on the car.
