Dear all,
Hummm, just realised the spare wheel for my Omega 2.5 V6 CDX (V plate) is a 15 inch one and only 205mm in width! The ones on the car are
225/55/R16. I have had the car from new and so no odd sizes fitted by other owners but the spare is on a steel rim and I have never used it (std CDX alloys fitted on car).Are all Omegas like this ?
What are the implications if I have to use the spare on the car - will I notice one wheel smaller than the other three on the car !
Andy.
My 1992 Clarton had a steel wheel with a 185 or 195 width tyre as the spare and 205s on the alloys. I'm not sure if that was standard as I was not the original owner of the car, but it wouldnt surprise me if the car was supplied like that. I think the idea behind it is so that you can drive to a place to get the tyre on the alloy fixed, but without so much of the handling/speed restriction placed upon you by a space saver type spare.
You might find that the rolling radius of the 15" spare is the same or similar to that of the 16" alloys depending on the aspect ratio of the tyres.
Either way, it won't hurt to drive with it fitted on a 'get you home' basis.
You will probably find that the spare is a different aspect ratio (the 55 bit) perhaps 70 or so , this would make the tyre roughly the same rolling radius.
You are unlikely to notice any difference in normal driving even if the spare is quite a bit smaller or larger, however the spare should only be used in order to get you to a tyre place to have the right tyre fitted on the punctured one in any case.

Yes. Not just Omegas, either. You very very rarely get a full size tyre or alloy wheel as the spare.
What size is the tyre? 205/65 15 is damn near identical height to 225/55 16
Treat it as a temporary spare, and don't hammer the car with the spare on, and you'll be fine. Or get a spare alloy with full size tyre, if it'll fit the well inflated.
I hate space-savers. The only current car I noticed with a full size alloy spare was my mothers celica.
Probably only on UK models. My jap 'ST185 Celica has a spacesaving spare. The boot wheel well is actually shallower. A full size spare sticks up well above the floor level. Mike.
My Supra had asymmetric alloys, so it had two alloy spares (via scrappies, I suspect)
You couldn't fit them both in the boot at the same time any which way.
And even the one that it was designed to fit stuck up a good 5" above the boot floor and had the carpet moulded to fit. Which made it next to pointless having any boot at all.
That kind of explains the spare on my old Xantia. It was exactly the same size and rating as the others but had a "Don't exceed 50 mph" sticker on it. I did wonder at the time but now I see that it was probably just a standard spare fitted regardless of the actual size of the normal wheels.
Our Previa has a space-saver. Daft IMO as it hangs under the car anyway
- so what space is it saving??

Ground clearance...?
Yep my Celica GT has the full size spare wheel, and its an alloy - I was quite surprised...
Cheers!
About a foot - no, I don't think so!
