 |
|
Hi
I have 5.200 5.25 x 16 cross ply tyres on my ford special and want to change to radials?
Has anyone used spacesaver tyres as a replacement. I don't intend going over 60mph or much motorway use.
If so, which size would be the best profile?
Thanks
Andrew |

Hi Andrew. By "spacesaver" if you are referring to the type commonly carried as a spare in modern vehicles, the please don't even think about it.
If not these, then ignore my reply.
Regards

To echo Peter, spacesavers are not intended for permanent fitment, 50mph maximum speed I think.

I believe they also require a special wheel which would be unlikely to fit a classic & at 60psi would probably blur your vision,cheers,JD.

Space saver tyres are rated at about 80mph, it's ony 50mph when they are used as a spare and you are mixing different tyre types on the same axle.
Why would they not be suitable as a replacement for a cross ply?

But you wouldn't use one other than as a spare as they're only intended for temporary use. You'd never run a car on four of them, they have limited tread depth (3mm max), run at a much higher pressure (60 psi) and are often made of a softer compound to compensate for higher pressure/narrow width. Stopping distances are increased too. Most car manufacturers recommend 50mph maximum.
I'd use one only as far as the nearest tyre depot.

| The tread pattern is only there to conform to regulations. Their water moving capability is virtually nil and as for snow... safer to walk outside in your beach sandals. |

nice to know how little new car manufacturers care about our safety!
Ive not had the chance to look at one, as the wife's new car came with a "proper" spare!
Feel stupid now for asking a stupid question, but thanks for the replies.

Andrew,
The ONLY stupid question is the one you keep asking.

Let's face it - no matter how much motor manufacturers try to dress up these "space saver" spares as being a good thing for the motorist in terms of increased luggage space or decreased weight leading to fuel savings, they were only ever about being a "cost saver" for the manufacturer.
It hasn't happened yet, but should I ever be unlucky enough to be lumbered with a vehicle that comes with one of these, about the first thing I will be doing is ringing around the breakers in search of a proper roadwheel to keep as spare, even if it ends up rattling round loose for evermore for want of sufficient stowage space. "Space saver" spares may be just about OK for footballers and the like poncing around London, but away from the big city, travelling rural roads, up in the mountains? I wouldn't trust one as far as I can spit. |

The Ford Fiesta is sold in Australia without even a space saver spare wheel. You just get an aerosol can that you are supposed to use to get you home after a flat. It'll almost certainly wreck the tyre!
When I questioned the salesman about the lack of a spare wheel, he had the cheek to ask me when I last had a puncture. He became quite upset when my wife pointed out that she had had a life policy on me for years and yet I hadn't died yet! It goes without saying that we ended up buying her a small Holden! (Which has a full size spare!)

... and that's exactly what I have done. I have now owned two cars issued with 'spacesavers' and I have immediately replaced them with full-sized spares. The silly thing is the originals didn't save any space, the spare wheel well took the full size as if it was made for one 
Edited to add: in both cases I was able to sell the (unused) spacesaver for more than the replacement cost  |

You even have to be careful with those, a friend had a Ford Fusion (the Fiesta on steroids ) car.
It had what looked like a standard pressed steel spare just like the steels on the the road, but it turned out that the wheel size was smaller but with a different tyre giving the same rolling circumference.
There was a 50mph warning sticker on it.
