Winding up spare tyre winch without a spare

Just as a follow up. Took off spare. I laid underneath and held tension on the cable as my wife wound the winch up. No problem and no issues. My main aim was to see how much difference it makes to rear axle load by removing spare from normal position and pitting it on roof rack as far forward as possible. The wheel is about 34kg with weight all behind rear axle as a lever. It adds about 45 kg to rear axle loading due to force moment. Went over the dump weighbridge with spare in normal sport and on roof. On roof it removes about a total of 30kg from rear axle loading. This will help when towing van as it gives me more available load on rear axle from ball load. Not much, but it helps.

Hi Briar,
What wheels and tyres are you running?
I'm surprised they're that heavy.

My 255/85R16 LT on steel Defender 130 rims with internal bead locks weigh 40kg.

I would have expected a D4 wheel to be close to half of mine.

Hey Tony

Last time I put them on scales was with the standard 19" alloys and I had Maxxis Bravos. Earlier this year I changed to Pirelli's, so I'm assuming they are about same weight. They were 34kg. I have a set of Moab 18" wheels with Nitto Terra Grapplers. They weigh 32-33kg each. The image below shows the standard ones I have. I wish they were 10kg lighter. As I get older they get harder to throw around.
