Speed limit on normal looking spare/emergency wheel?

My polo has that kind of sparewheel, after hitting a pothole 2years ago I swapped my damaged wheel with that one. On speeds above a hundred my car vibrated like a mofo as if not tightened well.

If the Polo came with mag wheels, then you are supposed to change to different wheel nuts when you switch to the spare. The tightening surface on the nut is different when compared with a mag.

Yes my car came with mags and yes I used the very same nuts from my original wheel

OK - you are lucky you didn't kill yourself then. :D

There should be a little plastic bag with 4 nuts in the spare wheel well - that is what you should use.

You try rotating tyres on the side of a road with a single jack - it won't puzzle you after that. ;)

Easy - Jack up car - remove good rear tyre on same side as punctured tyre, replace with marie biscuit, then remove punctured front tyre, replace with perfectly good FULL size tyre you just took off, and off you go!

All in all it should only take you about 5-10 more minutes (max) to change 2 tyres on the same side of a vehicle instead of just one, well worth it for the extra safety factor of 2 FULL size tyres on the front of your FWD vehicle!

I'm not comfortable putting that extra stress on the rim of the damaged tyre while I play musical tyres, maybe you are.

Maybe if you're looking at driving a great distance before you replace the tyre then it makes sense but my number one priority is getting off the side of the road and getting it replaced.

Take out marie biscuit, jack up rear and replace with marie biscuit, now go to front and jack that up and replace faulty wheel with functional wheel.

Still twice the work yes and doesn't mean the space saver emergency wheels are not the work of the devil. What is worse is there are cars that only come with wheel repair kits!!!

Saw an A5 around my neighbourhood a while back, jacked up, no rear wheel or driver in sight. Probably got a lift to the tyre shop. Funny but sad

On a normal size wheel (as he posted and what I asked about)? I don't think so. On a marie biscuit it is yes.

I thought that you were talking about marie biscuit tyres. By the way has anyone used those tyre repair kits? How well do they work?

Driving a great distance before you replace the tyre is risky behavior. You've now got no spare at all, and will be stranded should you have a problem. Getting off the side of the road and having it replaced ASAP makes far more sense. :)

It's basically the same thing they do when you take it in to the shops to be repaired. As long as the hole is in the tread, and you haven't driven too far with the tyre it shouldn't be an issue.
It can be difficult to do on the side of the road if you don't have a pump (sometimes even then you need higher pressure), or if you can't find the puncture easily. But something you can do at home. Works out cheaper to do it yourself, but I find it's usually easier to just take to the tyre place to do. I've had 3 screws in my tyres in the past few weeks.

I suspects he might be talking about those bottle things that inflate the tyre with the puncture and temporarily seals the hole. Also wonder how well those work.

Ah. My parents had a bit of a hit and miss with some of those. Think they had two in my Dad's car and two in the trailer, but all of them were probably 5+ years old. They ended up having 4 punctures on a long trip, one of the cannisters worked properly, one worked halfway other two were duds. But to re-emphasise they were probably well beyond any expiry date they may have had.
 
Those cans are rubbish. You will end up with a tyre that you have to discard once you have limped to the tyre shop. While if you had a spare wheel to use, you could have changed the wheel and had the puncture fixed for R50 instead of buying a new tyre.
 
Those kits might help you get to the garage after a puncture, but wheels can burst, be cut, or can get punctures in the sidewall. :confused:
