What tire pressures are you guys running with Comp 666 wheels?

Alan l. · 07-24-2018, 09:58 AM

Pretty sure on my 2018 zcp M3 door jam says 32psi all around cold. That seems extremely low to me. All my years of driving i've always had atleast 36-40psi in my tires. I tried running higher psi and the ride quality went to shit. Felt like rolling on solid tires without any give. Is everyone sticking to the factory recommended values with 20"s?

i run 32 as suggested on the door jamb

whatever you do - don't go to cars and coffee and have it off by 1.5 psi. you'll wind up on the internet!

32 psi cold on PS4S 666m

MPoweRo · 07-25-2018, 12:19 AM

31-32 with PSC2.

JibSTir13 · 07-25-2018, 12:13 PM

~32 psi cold per information on door jamb.

On a side note, the TPMS didn't inform me of low tire pressure until the tires were at around 28 PSI.

The door jam pressures on my 2016 M4 Comp pack with 666's are 35psi front and 30psi rear. Does it vary on M3 to M4 or year to year???

I inflate mine to 33 PSI so my iDrive reads 32 PSI (idk why the computer is always 1 PSI lower)

instarand · 12-08-2018, 11:44 AM

32 front and rear per the sticker in the door on my '18 F80 CP.

There's been some very slight adjustment in recommended pressures over the years. However, it's the first time I hear about your 35/30psi front/rear for 20" summer tires. Are you sure you read it right?

36 psi

I was just talking to the sales manager at the local BMW over the weekend. He has a ZCP M3 with 666s. He came out, felt my tires, and said that I needed to run 36 instead of 32/33 in my 666s. I questioned it, but he said that the tires wear and handle better with 36. I'm going to try it.

I used to have a e46 convertible with a soft top. I never like the soft top but like the look with top down. It's almost bring back me to my 20's .
The reason I got a convertible f83 was cause it's a hard top , I don't drive it to often with the top down but I like the option.

I had the same car with the same color minus the chrome wheels and add BBS wheels and add the black kidney grills. That car brings me back to the tuner days it also reminded me of my old e30 then which I loved. I hope the next gen M3’s looks as good as they keep making them every single gen
