So if you can weigh your alloy with (hopefully similar tyre) and we may have an answer.
My current wheels are the Defender steel rims with 7.50 16 (OD just below 33"), and they weigh a bit over 32kg each.

my other tyres are 255/70 but I don't have anything to weight them on...

Range Rover Classic 3 spoke weigh 10Kgs each and I can confirm the 13Kg for the steels.

Bigger tyres weigh much more than 205x16s , so were you comparing apples with apples? ie did the alloy spare have the same tyres as the steel road wheels?

Also tyre brand / composition of construction makes a HUGE difference...


Maybe he just had his Weetbix before lifting the Alloy that day :wasntme:

The alloys must be half the weight of the steelies, so they should be easier to get turning, shouldn't they?

Mate,

I had the original Defender rims on my Cab Chassis when I brought it. I decided to fit the early RR rims (the ones that look like a spaceship). I chose these cause they arn't a bad rim n r built like a tank.:D

So just for a laugh after I purchased 6 of them and had them fitted with Cooper ST C I jumped on the scales with one.

The original steel wheel had BFG Mud Terrains on them and were 7Kg HEAVIER :eek: than the CSK RR rim with what I suspect was a much heavier Cooper ST C on it.

To have reduced the rotating mass of each tyre rim combo by 7kg must make the bearings life a little easier if nothing else :cool:

yep

Ok. basically, changing steelies to alloys will probably show as much difference in performance as getting round with 40l of fuel in the tank instead of 55.....
Does anyone notice a difference between a nearly empty tank vs a full one?
Admittedly I think I do, but I have a LR tank....
Does anyone notice a difference with only the driver vs drive + one passenger?
Does anyone notice a difference when driivng at night with lights and heater + fan on with the alternator doing its thing vs daylight driving with none of these things?

I doubt it - and if you do - the difference will be so minor it really won't help anything anyway.

These cars are never going to be performance vehicles, torque is power, not zip....

My 2 cents...
