spare wheel ?

[Si Mcinerney]

Just jumping onto this thread as a new Zed owner. I dropped my spare wheel and it’s more rust than metal. For completeness I was contemplating sourcing a 2nd hand replacement. That said the spare is a a 15” and the Zed’s wheels are 18”. Apart from anything bigger not fitting the carrier, can a 15” substitute the 18” to get home?

Got 19s on my Blue 2.8 and ripped a hole in the side wall of my rear tyre. Luckily my 21yr old spare was in fair condition. Got it on and filled up the air. Did me well sticking at 50mph for the 200 mile trip home.

The important thing is to keep the rear wheel diameters the same, this to prevent damage to the differential.

yes because to rolling circumference should be the same for the tyres.the sidewall on the spacesavers is much taller than the road tyres.

If you look on this link and play around with your tyre sizes you will be able to see the speedo difference as you change tyres.
