I was wondering if it would be OK to drive the VX on a space saver tyre in an emergency? I have a 115/70/R16 space saver that would fit. The overall diameter of the wheel and tyre is about 22 inches, the standard VX wheel and tyre is about 24 inches. Would the 2 inch difference be a problem, obviously handling is going to be affected anyway running a space saver. Thanks

I suspect this would cause problems with the abs as it'd be turning faster that the other wheels.

and where do you propose to put it when not in use

Hmmm I thought about space saver wheels but then considered if I do manage to find somewhere to squeeze a skinny wheel If I have a puncture and fit the skinny where do I then put the huge rear wheel to get it home ? 😃

I hadn't thought of that but I think you're right it would be a problem.

I hadn't worked out where I was going to put it, I was just seeing if it would work.

When you swop it over you give the huge rear wheel to the passenger that what they are there for

I don't see why you would want to. The foam works well enough in an emergency and the tyre can actually be reused afterwards (depending on the type of puncture)

I keep one standard front wheel & tyre at home and one at work just to getting me going in the event of a puncture at either of those venues. Also I have to have a jack in both locations. At a push I could use front wheel and tyre on rear, I have done worse things in the past! In the case of slow punctures I have a electric pump in the car just to get me to a tyre repairer. I have heard the foam is a hit and miss affair. I'd avoid at all costs risking losing a tire due to using the foam. Kind regards, Paul

As long as you replace the canisters regularly they will work; the problem most people have is by the time they come to use the foam it is well past it's use by date.

That said, given the situation I would much rather call the AA and get them to recover me rather than putting that gunk into my tyres.

I had to use the foam in the BMW when it developed a puncture on the way back from Cannes (no spare in there either). Got me the 600 or so miles left and my mate (whose car it was) drove it around for a few months before rplacing the tyre. It works perfectly.

Avoid (where possible) putting the different wheel and tyre on the driven axle... As the different rotation rates are not good for the drivetrain. Having a significant difference in rotation rates cannot do the gearbox / diff any good at all.

AA, RAC,Green Flag and so on its what you pay them for. If its a cut and not a hole like Craig had in Scotland you Don't have a lot of options . So get some of your money back. They can take you wheel for repair and bring it back or take you and your car to the tyre place,job done.

If you have differing rolling circumferances on your drive (rear) wheels it will play havoc with your diff.

[Paulus H]

Many OEM spacesavers have a different circumference to std wheel. In this case one driveshaft will be turning faster than the other and the sun and planet gears in the diff will be turning - which is exactly the same scenario as when the car is driven along a twisty road. Don't get me wrong I would not recommend this for a track day. I think nearly all of the users of this site are very safety concious, of course I would not recommend using a spacesaver (of any kind) for long distances AND I would recommend the utmost caution and care when driving with any kind of spacesaver. Kind regards, Paul
