'92Q: Michelin Pilot Exalta AS vs. Yokohama Avid H4S

[bruce.weiland]

Brian,

OK, I'll bite.

I have weighed my current setup. Based on a 24 lbs tire weight I get 11 lbs per wheel. That could be incorrect because the Michelin Symmetry 215x65x15 may not weigh 24 lbs. But, based on the tire rack info that is what I come up with.

I do know that my current setup IS 35 lbs.

The Pirelli is 25 lbs, according to the Tire Rack website. Therefore, the BBS with the Pirelli 225x65x15 should be a 36 lbs. combination.

Does that make sense to you?

I recall the BBS weighing 16.5 lb., the 235/60-15 XGTH can only be extrapolated to weigh 26 lb. since the 225/60-15 Exalto weighs 25 lb.

Brian,

You may recall correctly. The BBS may weigh 16.5. And, I am sure you are correct about your extrapolation.

However, I was not extrapolating the XGTH. And here is why I am confused about the weight of the OEM tire.

I was exprapolating the tires that are currently on the car. Michelin Symmetry 215x65x15. These tires are not listed by Tirerack, but the two below are.

Michelin Symmetry205/70 SR15 95S SL 500 A B 1499 lbs. 35 psi 10/32" 23 lbs. 5-7" 6" .8" NA 26.1" 796 215/70 SR15 97S SL 500 A B 1620 lbs. 35 psi 10/32" 25 lbs. 5.5-7" 6.5" 9.4" NA 26.5" 781

Therefore, the tires currently on the car should be around 24 lbs. each, and because the tire/wheel combination weighs 35 lbs (my digital scale rounds up or down to the nearest pound) that only leaves a weight of 11 lbs per wheel.

If the wheels weighed 16.5 lbs the tires would have to weigh 18 to 81.5 and I think that is not probable, given the construction of the other sizes above.

http://www.wheelweights.net lists two 15x6.5 BBS at 9.9 lbs. Most very low weight wheels that I have seen are 5 spoke and veyr open, so less material/metal in the first place. However, the forged BBS RG-F looks somewhat similar to the OEM Infiniti wheel. So, I don't think the leap to a 11 lb weight for the OEM is such a big jump in thinking.

I guess we really won't know until someone takes a tire off one of these "lace" wheels and weighs the wheel by itself. Or, if someone has the specs on the OEM in print somewhere.

I am with you. It is hard to believe that Infiniti put such a light wheel on the car clear back in 1994.

If no one weighs them before I do, I will take a scale with me to the tire place and weigh a wheel when I put the next set of tires on. I don't currently have any tires ordered.

I guaratee the BBS wheel weighs more than 15 lbs., probably more than 16 lbs. I believe someone weighed them before and posted.

I have no idea what the Symmetry tire is.

For a reference, the stock OEM 20 port 16x7 FGY33 wheels are ~20 lbs.

Followup:

Based on the advice here I purchased the Michelin Exaltas. The lack of road noise alone would have been reason to purchase them, let alone the smooth ride. Wow....!
