I have a 2017 Transit campervan, which when converted, had 18" alloy wheels put on. (tyre size 235/50ZR18 101W extra load)
Just discovered the spare wheel strapped under the van is a 15" with tyre size 215/65R15 on it.
Can this be used safely as a 'get you home spare', or is using this 15" with 3 x 18" others a 'no no'?
Also, would like to get winter tyres for it. Rather than putting winter tyres on the 18" alloys, I thought I would buy a set of steel wheels, put winter tyres on these,
and put them on the van, storing the 18" alloys with their original tyres on them.
Problem is that there appears to be so many different wheel sizes for different transit models.
So apart from physically fitting a wheel to the van to make sure it fits, how can I tell if a wheel will fit my van before I buy?
Buying off of Gumtree or Ebay, so have to know before I buy.
Thanks
