Stock OEM size MPSS so what's the optimum street tire pressures F/R?

Thanks

Manual states 33/39 for partial load and that is what I run.

I'm usually sitting at 37/42, after they warm up

37/40

+1 But, both sensors on my left side just failed so I'm replacing them all along with the stems. If you need to replace yours I suggest calling Suncoast for OEM; they are less expensive.

I like 6 lbs between F and R, in the range of 34/40 cold, 37/43 hot.

C2 Turbo

Cold or warm

I am sure, we can set the PSi number for TPMS, right?

eurotom

Cold. TPMS does not have setting for hot/temp, only partial or full load.

I run 31/36 cold with Pilot Super Sports. Works really well with the suspension set-up I have.

32 front 36 rear cold on mpss
feels great.
i run 30 and 34 on my r888s

C2 Turbo

I set mine up at 33 F and 36 R (Cold) and though car feels great but the TPMS keeps saying "-4 psi" in rear

What do I need to do here?

Are they pre-set at certain numbers from the factory? Do I need to reset the TPMS?

Thanks

Street 37/40 hot
track R tires 32/36 hot (big track like wgi)

I am going to use my P zero Trefeo on street. What pressure should I run on street?
Will higher pressure cause a big performance decrease? on track I run 30/33 hot.
But I am not sure I should run that low on street

The TPMS is expecting 33/39 and if it drops 4 PSI below that the warning comes on. So you may consider going to 37 PSI in the rears and see if your tire gauge and TPMS are in synch. I have a very good tire gauge and my TPMS is consistently off by 1 PSI. That's one of the ways I avoid the dreaded !

^ I see a bigger variance in TPMS vesus a quality gauge. More like -3 PSI from actual.
