The standard 15x 5" wheel fitted with 165/80/15 Continental Contact 1 tyre.
Just weighed it to keep Peter happy
15 x 5" painted steel wire wheel plus 165/80/15 tyre = 17.3kg
Continental Contact 1 165/80/15 tyre = 6.9 kg
Roadster standard alloy wheel 15 x 6 1/2" plus 205/60/15 Avon ZV5 tyre = 17.3kg
Someone earlier mentioned the splined alloys by Minilite. I was thinking of fitting these to my 4/4 at one stage until I picked up one and realised just how heavy they are with the bolt in splines! A shame that Minilite won't make a non bolt in spline wheel like the one fitted to the Plus4SS available to the public.
PM me Graham if the wheel and/or tyres are of interest.
