Space saver maximum speed

Depends on the type of spacesaver. There are the slim donuts that are limited to 50mph/80kph and there are the fatter ones in some markets for up to 80mph.

I'm unfamiliar with these - any links or more info, such as sizes?

I reckon 90% of the UK could have space savers front/rear 24/7/365 and never have to worry about the limit, because 90% of the UK seem to be glued to 40mph anyway.

Just wondered. It has a sticker attached saying "max 80kph", yet the speed rating is "M" which would imply a max speed of 81 mph.

The maximum speed of the tyre might be 81mph, but the maximum speed of the wheel and tyre in the scenario of your car is lower.

Either way, it's an emergency wheel, get the proper one sorted.

What I don't understand is why they put the 80kph stickers on full-size spares as well.

My car came with an unused spare, with a brand-new Bridgestone tyre, the same size as all the other wheels, albeit steel. The tyre is exactly the same as any other of its size, so why the 80kph?

I had one on an Espace rental car and had to change the tyre.

I would think so, a bored worker with a roll of 80kph stickers.

Thanks for that - I hadn't read that issue.

Three things arise from that article -

1. The 80mph sticker would be wrong as even a higher rated spacesaver is still a spacesaver and under the rules would still be limited to 50mph/80kph. Renault would appear to acknowledge that.

2. In the 2nd paragraph of the article it days that fitters find worn spacesavers proving that they have been run for more than the 50 mile limit.

As far as I understand there is no limit for how far you can legally drive on a spacesaver.

Most sensible people would drive the minimum distance possible to get to a tyre fitters workshop for a repair or a replacement tyre, but I don't think that there is anything to stop you say driving a considerable distance more than 50 miles if you had a puncture on a bank holiday or on a long overnight journey.

3. It is repeated a couple of times that a run-flat tyre cannot be repaired. That's a load of rubbish - they can be repaired like any other tyre - as long as they satisfy the usual requirements of position on the tread of the actual hole, and no side-wall damage due to running flat.

I carry a spacesaver and as soon as the Tyre-Pressure Monitoring System alarm goes I stop and fit the spacesaver - that way there is no further damage to the tyre.

I like run-flats as if Mrs Iceweasel had a puncture I'm happy to know that she could continue without any safety problems in changing a big heavy wheel or in a dangerous location.

I'm prepared to accept that her doing that my wreck the tyre - but it's not a 'given' that run-flats cannot be repaired.

I realise many tyre fitters won't even look at the tyre - and simply want to sell you a new one.

Another country, but seen a car running on about 3 worn out skinny space savers.. The remaining full size was down to the threads as well..

Still be in the outside lane though despite the inside being clear and of course, totally oblivious to everyone behind them...
