Car and wheel/tire weights - 2SS NPP MRC 6SPD
 
**** I edited this first post with additional information on OE wheel and tire weights and some fitment information ****

I weighed my car on calibrated vehicle set up scales the day I got it (1/29) and also weighed a front and rear tire/wheel assembly on very accurate scales. Both at work, an ISO certified place so they are checked regularly.

2016 2SS, 6SPD, NPP, MRC, no sunroof, 56V (low gloss black 5 spoke wheels), full tank of fuel (2 miles from gas station).

LF = 987 lbs
RF = 1021 lbs
LR = 853 lbs
RR = 874 lbs
Total = 3735 lbs

OEM front wheel = 29.32 lbs (no weights or center cap, includes TPMS sensor)
OEM rear wheel = 32.30 lbs (no weights or center cap, includes TPMS sensor)

OEM front tire = 30.02 lbs (only 280 miles on it)
OEM rear tire = 32.07 lbs (only 280 miles on it)

Conti DWS 06 front tire (245/40R20) = 27.08 lbs
Conti DWS 06 rear tire (275/35R20) = 29.42 lbs

Hankook RS3v2 275/35R19 = 29.03 lbs

19X9.5 ET36 aftermarket wheel = 24.60 lbs

Rear OE fits on front with 9.8 mm spacer but is very close. Better with 4 spacers at 13.1 mm. Still closer to the strut than the OE front. Best would be using 15mm spacer.

19X9.5 ET36 aftermarket barely clears with 13.1 mm of spacer. 15 mm spacer needed to clear strut to inner wheel lip.

Good information. Thanks!

I edited my original post with more information. Added OEM wheel and tire weights and also some fitment information for different offsets to work on the front. I did not drive the car with these fittings, just bolted on while on a lift using 4 spacers. The wheel studs are NOT long enough to use slip on spacers in this quantity, but worked to check clearances.

I have some 15mm bolt on spacers, but as crankaholic and I have found, they don't play will with the stock wheel stud length and various wheels. Shorter studs or wheels with deeper backside pockets are needed for them to work.

Do the 6th Gen OE wheels have the same geometry and bolt pattern as the 5th Gen wheels?

Just curious, because those new 1LE wheels look pretty cool :)

Sorry if I cant wrap my head around the wheel stud issue.
You add a spacer, push the rim out, but the studs are to long?

I would think you would need longer studs.

Yes, they have the same bolt pattern,5x120. The needed offsets change with changing widths. Lots of information on this forum from wheels suppliers on what fits.

The spacers on bolt on, not slip on. Once you get over about 10mm, the studs would be too short for enough lug nut engagement like you said. So the bolt on spacers go over the oe studs and bolt on using small nuts. Then the spacer itself has studs that the wheel bolts to. So the oe studs stick through the spacer and the wheel needs to have a pocket to make room. On the new car, the oe studs stick out 25mm past the spacer, so the wheel needs a 26mm pocket. The wheels I've checked have an 11mm pocket.

Sorry I don't have any pics, worth a thousand words....

Ok. I get it.
Sorry for the foggy brain.

I will look into this more with my go to tire shop. See what they come up with.

oh you have what i think is a small adapter style spacer. on a easy fix you need a bigger spacer,, second option is to add shorter studs...which rarely needs to be done and only if you want to use the spacers you purchased, or add a regular 10mm spacer and use these babies et lug nuts which will give you that extra 2 turns or so that you need.

Thanks, I hadn't seen the ET (extended thread) nuts. Yes those would probably do the trick with a thinner spacer. But 15mm gives the the offset I need. So I'm down to using shorter studs. Or as you say, a thicker spacer but with my wheels I'd need a 29mm spacer!

60ish pounds per tire mounted on wheel?

Crazy question.
Why not consider wheels with the proper off set in order to eliminate the spacer? Or better yet wider wheels upfront which the car can take.

I bought the spacers for a set of winter wheels - 19x8.5 ET35 wheels are plentiful and much cheaper than ordering a set with a proper offset... considering winter tire grip and less enthusiastic driving style, using a spacer to bring the +35 offset back to +20 is a cheap solution that won't hurt anything in this case.

Using a spacer to offset a wheel further than stock will have negative consequences... both short and long term.
