Apex PS-7 18x8.5 Wheels BMW E46 ZHP

Hopefully it's just the bathroom scale being inconsistent.

Have you tried weighing yourself and then weighing yourself again holding the wheel? I tend to do this for shipping weight for items below 50lbs

Sorry guys for the late response! I was promoted at work to clinical research manager last week and things have been quite busy to say the least . I also somehow contracted the flu, so I'm taking things a bit easier.

YES. Bathroom scale is INACCURATE. I weighed them again multiple times and got different results... Variation of ~1 lb I think, and since these aren't calibrated, who knows what the offset is either. I'll try to find a more accurate scale to re-weight them.

Congrats on the promotion! More discretionary income? ;-)

Thanks! It was a significant raise. Yes... 90% will be discretionary. LOL. No, I'm rather frugal. FWIW, I weighed myself and held the wheel on the bathroom scale and it returned an average of 21.0 lbs for all 4 wheels this time. A little odd, but I've come to realize this isn't the most precise/accurate method to weigh them...

Ok. I weighed the style M135 18x8.5 rear wheel on the same scale using the same methods as the Apex PS-7's (weighed myself, picked up wheel, re-weigh, subtract).

It weighs 56.0 lbs with a 255/35/R18 bridgestone potenza RE040.... Which also happens to be the tire that is in this link:

I have 30k on the tire and it's deflated (flat). Tread is 5/32 so it should weigh lighter (if anything) than the quoted 25 lbs for the tire weight... Which would mean my M135 wheel is ~31 lbs according to my scale!???? Holy cow...

[ELCID86]

That's about right. I just paid to have 4 135s shipped.

Tire Pressures

From Tru-Line Bellevue:

"****PLEASE MAINTAIN TIRE PRESSURE SETTINGS OF 40 PSI FRONT AND 36 PSI REAR AT ALL TIMES FOR BEST TIRE LIFE EXTENSION AND FUEL ECONOMY IN THE SEATTLE METRO AREA.

That caught me by surprise as I inflate my stock wheels and tires the other way around... ~40 psi rears and ~36 front... But I assume they know best. Anyone also do 40 psi front and 36 rear???

With 10mm Spacers

Looks Perfect!!!

I'm really considering the spacers (they'll definitely improve the look!).... But the rears already stick out a little further than stock, so I think I will pass and instead get an alignment. I'm due for it! I'm getting used to the new look but being so familiar with the stock wheels makes me miss them.
