Weight of Double Five wheels

I have absolutely no idea, but perhaps Dave at DCR can answer your question. Jaguar XK8 XKR Double 5 Alloy Wheels Set | Jaguar XK8 and XKR Parts and Accessories
Since they ship them, they should know the weight. Remember, the fronts and rears are not the same size. Eight inch (front) and nine inch (rear).
Cheers,
Stu

Higgins the Double Five man!!
Higgins, They are all made of some kind of Aluminum Alloy and the weight difference of all the Jaguar Wheels would not be enough to matter....The Double Five Wheel is smaller in size than the Montreal or the Detroit wheels as they are both 20's. I don't think the Double-5 is more than 18" and not as wide as the Detroit which comes in at 9" Front and 10" Rear....Weight doesn't matter on an XK …it's the Beauty that counts! If you like the Double-5, then that's the Wheel for you! What kind of Wheel do you have now? Someone with Double-5's might want to trade.....

Hi,
when it comes to performance and fuel consumption, every pound or kilo counts. Of course xk8 is not the car if you want outright performance or minimum fuel consumption, but I would still like to improve both. Also, light wheels improves ride quality since unsprung weight is malicious. If 3 or 4 pounds can be saved at each wheel, gains are made. In this case I dont hope to find a decent set of Detroits or Sepangs since they have become to expensive. I look at using BMW wheels with 5x120 pattern together with conical bolts. I found a wheel Miro 110 with the same specs as Coventry whitley, that is 20" ET20 front 8.5 rear 9.5. Weight is 29.5 pounds front and 30.5 pounds rear.
So, now I would like to compare weight with my Double Fives

Higgins

this may be too simple of an observation, but have you thought about just taking a wheel off of the car and weighing it ? Every tire manufacturer I know of publishes weight specification for their tires. So finding out that should be easy as pie. Weigh the wheel / tire assembly then subtract the tire weight.
That should take you all of 10 minutes to jack up one side, get the wheel off of the car, weigh it on a digital bathroom scale (they are very accurate). then put the wheel back on the car. If your scale won't go as low as the wheel / tire weight, just pick it up and get on the scale. Then weigh yourself without holding the tire. Subtract higher number from lower number and there you have the weight of the wheel / tire assembly.
In any case, following the above procedure will take you less time than waiting for someone else to post the answer.

Well Higgins, Why didn't you do that in the first place? Do you think that we are going to go out and find a Double-5 and weight it for you? I told you that all the Jaguar wheels weight about the same......and by the way what model and year Jag do you have to start with?
Do you even have an XK8 or XKR?

The performance changes you are going to see or feel are going to be negligible if all you are doing is saving a few pounds per wheel. You'd be better off dumping your spare tire in the garage.
Our cars are heavy and not exactly meant to be sports cars. MAYBE you'd see some quantifiable difference in the track, but I'd not bet on it.
The one thing you can be sure of by reducing rotational mass is that your one of your rear tires is going to turn into smoking sticky goo more quickly.
Relax and enjoy the look!

Hi,
As I wrote yesterday, I am aware that the XK8 is neither the car for outright performance (unless you change your SC to a bigger better one) nor minimal fuel consumption. Still, I want to reduce weight where possible without ruining the strenghts of the XK8. If weight is reduced in many places, maybe just a pound or two in each place, in the end performance gains will be made. Yes, I have thought of changing seats from my worn standard seats to new reclinable Recaro or Sparco seats without electric motors in them. Weight of such Recaro seats are 33 pounds each. That is maybe 30% of the weight of the standard seats. If my seats where not worn I would probably not bother but since I need to do something about them, why not reduce weight at the same time?
I have the greatest respect of the XK8 owners that wants to keep their cars 100% original, and I never get rid of the original parts that I swap for aftermarket replacements. Some day I might want to restore the car to 100% original spec
Regards,
Henrik

Bill,
no I dont expect you to go out in your garage and put your wheel on the scale. My humble question was aimed at those who might be in possesion of the knowledge of this kind. If you dont, please dont be offended by my question. And yes, I am the proud owner of a 2000 Xkr coupe, platinum gray

I am not entirely sure saving weight on the wheels will necessarily save on gas. Might be slower to accelerate, but also harder to slow down. Braking less and driving more on momentum save a ton of gas. FWIW, most people would say 18" is a great choice for our cars, good compromise between comfort (more sidewall, less un-sprung weight) and performance (for a luxury car), and even leaves room for big brakes. Tires tend to also be cheaper. I had a set of heavy chromed 19" Apollos, and changed them to a set of 18" hydras. Way better for me in just about every respect. Of course these nicer 20" wheels from the later cars look incredible, but I am not willing to do what it takes to get a set, mostly because of cost.
Jaguar wheels are cataloged "everywhere", but hardly anyone has them available Search "jaguar 59713". If you search long enough, maybe someone has a weight listed.

Remove unspring weight is different from removing sprung weigh. A savings of ten pounds per wheel will have a dramatic effect on suspension travel dynamics; while removing forty pounds from the car will yield negligible effects. Less unspring weight allows the tire to follow the contours of the road better.

That being said, the double fives are a smaller wheel, but if they're at all comparable to the revolvers in terms of weight, I would probably look into aftermarket wheels instead. Obviously every pound counts, and it all adds up, but wheels are one area where saving 10 pounds a corner might actually be a big deal, so it might be worth going for bigger weight savings there.
