I did this awhile ago but some of the tires were worn.  I weighted my wheels and tires today.  Getting ready for the car show I removed the HREs and installed my VR1s.

Stock GTS wheel weights for the front are     58.2 pounds each.  PS1 tires that look like new.

HRE 3pc wheels with Like new KDW tires are   54. pounds each. 

The VR1 wheels and new PS2s I installed are  46.8 which s equal to more than 11.4 pounds each for the front wheels.  Probably 15 pounds lighter than the rears (guess)  which would make the VR1s nearly a 50 pound weight savings for the car.

HREs are about a 18 pound weight saving. 

That is a huge difference.

Good to know the stock GTS weights.

I have my ACR wheels and BFG KDW tires just sitting in the garage.  I'll weigh those up and post results.

That would be helpful, thankyou.  I'll also weigh one of my old tires that are worn, but still legal so we have an idea of what a tire weighs without the rim.

Weighed my chrome ACR wheels off my 1999 using a Weight Watchers scale.


51.3 lbs. for the fronts.
61.7 lbs for the rears.

KDW's maybe had 5000 miles wear.

I was not able to get a Body Fat reading.

Rule of thumb is every pound of unsprung/rotational weight removed for the track will have the effect of 8 lbs off the car. If you've taken 50 pounds off, total, your wheels and tires it will improve the performance the equivalent of taking 400 pounds off the car. Yup, that much.

I weighed my factory wheels before I shipped them. fronts were 23Lbs and rears were 28lbs ,no tires . They are the later forged ones like your. Sure is a big difference between the 17x10 and 18x10, 10lbs or so. Yikes!

Yes there are huge differences in weight, but also strength in many cases.  I watched a rear sidewinder wheel on an ACRX catch a rock in the 'barrel' and the rock got caught against the brake caliper.  It wore all the way through the wheel and dropped the tire and the inner part of the wheels was just bounding around on the car.  It was during a race and it was cool watching the OTHER Pit Crew fun over and help change the tire!

I'll take my weigh scale outside and measure my 19" CCCWs I just bought from C-note ...
