I would like to save space in the boot and also a bit of weight on the spare tire.
I have a 5.5 Mahle rim and I wondered what is the smalest tire that could fit on this rim ? I was thinking of a 135/80.
I don't care about same size as the other wheels, I would only use it as temporary spare
I could also hunt for a 4.5 steel rim (paint it red) but I don't think I will save weight with this one.
Of course there is the "no spare" option, but I don't like it.
