Space tyre

[bazjude2998]

Not sure if this is the right forum
Will the tyre off a space saver wheel 125 -80 15” fit on a 15” x4” wide wire wheel
Thanks

Proberly? What it going onto?

[InitialDave]

Should do, yeah. But why?

[GreenV8S]

It would need to be designed for the same rim section, and the right size.

[finishing touch]

As they are made to replace a tyre three times the size and run at twice the pressure I would think the sidewalls are built like nuclear bunkers.

The tyre is going onto a 4” wire wheel as stated.The issue is limited space to stow the spare
It’s a 1962 Grantura
Thanks

The issue is more likely to be the other way round, as in, is that rim designed for that tyre as in, tubeless.

Presumably the other wheels have tyres, of a known/working spec, but don't fit in the spare well? Owners club you can ask?

If it's a spare I wouldn't worry too much about stiff sidewalls, but obviously it needs sit in the rim nicely. Would you be running it with a tube?

Yes I think it would have to have a tube
My real concern is would the tyre fit a spoked rim or are these space saver wheels and tyres designed specifically to match each other

[dhutch]

As far as I know 'space savers' have the same rim profile as any other modern tyre.

I think so too. I have no idea whether you can say the same of an unknown wire spoked wheel.

[finishing touch]

As a spoked wheel has a pressed & rolled rim I would think you can see the rim profile from the outside, minus a thickness of metal.



As a matter of interest has anyone taken a space saver tyre off the rim? I have two, both over 16 years old but they are not the sort of thing
that you ever replace. Mine still have the cast nipples on them, although one has done six miles.

What about the speed rating of the tyre? Space savers are normally marked at 50mph or so, I'm not sure if that's the limit of the tyre or just because it doesn't match the other 3.

Valid to check, but if it's only for the spare...
