Put space-saver spare on which axle?

[nicko]

If you're going to run with a space-saver, and are unfortunate enough to need to use it,
which axle are you going to put it on?

With FWD cars it seems fairly clear the advice is to put the space-saver on the rear axle.
If you have a front puncture, you swap a rear for the SS, then the punctured front for the good rear.
FWD are unlikely to have different rim/tyre sizes between front and rear, so it's easy to do.

now, assuming you're not going to go very far, and you'll be keeping it down at a sensible speed

With RWD I *think* I'd still want the SS on the rear if possible (if the rolling circumference is very close)
Is this the best place for a space-saver on a RWD?
If your rears are wider, how well will they fit in the front wheel arches?

Well the answer is in the last line of your question in that if you run a staggered set up the rears will not fit on the front without rubbing ( well not on mine for sure on 108's)

Frankly if I get a flat it's going on the corner that deflates and with just an emergency jack there is no way I'm doing a multil wheel swap.

Just use the up to 50 miles at 50 and easy on the gas and brakes.

Unless you've got your winter wheels on, and they're narrower than the normal wheels.
Then a rear will fit the front

and then you've got three winter tyres with loads of grip... and a skinny, non-winter, low tread depth, space saver

I don't understand your post and what you're saying?

A rear 8.5 J oem rim will not fit on the front without the inner face rubbing on the suspension strut. I can show you photos of what happened to mine when a tyre shop did it in error. A front will however fit on the rear without problem

My simple logic tells me SS should always be on the rear axle, because the size difference will not affect the steering.

Put the SS on the wheel which has a problem, simple

Ditto.. Whichever wheel has the flat tyre.

sorry.
I have now finally got my winter wheels on, and they are 7.5" rear / 7.0" front rims, so the rears can fit the front.

Haven't been far in them yet, but the ride is so much better than with the Bridgestone RunFlats
