Ride quality seems good when tyres at cold pressure, too firm when tyres warm up

Neat, I didn't know Tesla fits 18" performance tires from the factory for some markets (I see you're in the UK). Were the 18" PS4S standard or did you check an option for them?

They don't. These are not PS4S's they are PS4's. Different tire. Yes, it's confusing, but blame Michelin.

New 18" Pilot Sport 4S - Tesla Spec

Just saw these new Tesla Spec-ed (Acoustic Foam, Eco-Focused) 18" tires (235x45x18) Michelin Pilot Sport 4S tires. I'm wondering what new rim's Tesla is aiming to provide with these! Could the new referral forged wheels be 18" diameter?!?!

However, its unclear that these actually ever came on a Tesla stock.

Ah I do remember seeing PS4 - not PS4S! - in 235/35R18 Tesla spec on tire shop websites. I don't recall ever finding a way to spec 18" summer tires from the factory on Tesla USA Model 3 config page though.

I guess this explains why those tires exist, they're factory fitment in other markets. Nice of Michelin to sell them in the US anyways, though even Michelin seems to steer consumer tire buyers towards the PS4S over the PS4.

Whoops, sorry for the confusion. I checked and indeed I have Pilot Sport 4 (not 4S).

I lowered mine from recommended 42 to 39. Didn't seem to make a difference, but got the amber TPMS warning which was still showing when they warmed up to 40 (but only on the front tyres). I'm booked in for a service so added this to the list as I thought TPMS warnings were triggered at -20% or about 34 psi.
