Weight of wheels
My wheel and tyre package weighs 14.7 kg. It is 14" with 185/60 A-021 tyres. Is this good, bad or indifferent.

Adam,
My wheels are 15x7 Simmons B45's (a three piece rim). See the Simmons web site for a pic
although the B45 is no longer available in 15".
My tyres are Simex SM8000 205/55-15. Each tyre/rim combo weights just under 17kg which sounds comparable with yours.
Hope this is of interest,
Dominic
Brisbane, Australia

The other day I pick up a 17" x7 alloy wheel in my local tyre shop and was a mazed how heavy it was ----
Just to put a perspective on this a 8.0"x13" Revolution 4 spoke wheel with 7.2-20x13" racing xply slick weighs about 18 lbs ---
about half the weight of a fctory steel rim with a 165x13" radial. --- 18 lbs is bit over 8kg and the Revolution isn't an ultra light
wheel a proper thin rimmed single seater racing car rim would weigh about half the weight of the bare Revolution rim which is really more of a
forest Rally wheel from the days of the Mk2 Escort.
Of course a racing Xply tyre dosen't have a steel belt, but allowing for that it points to the fact that that majority of alloy wheels sold
these days are designed for fitting to big heavy cars and the designer gave little or no thought to unsprung weight.
A good wheel manufacturer will have the weight of typical sizes in is brochure, also look for the the type and grade of alloy used. With aluminim
alloy look for LM3 or LM25 or better still heat treated LM25.

My wheels were designed by kn for the caterham classic de dion. They should weigh a bit less when I swap the tyres for 185/55 A-032Rs.
A SLR split rim weighs about 31/2 kgs without a tyre.
