What's the recommended air pressure for my 2010 GS , with newly installed Michelin Super Sport non-RunFlats ? ( stock sizes )

Discount Tire installed them at 26 psi , but that seems low to me ...

Where do you guys keeps them ? ..... 30 psi like my old Goodyears ?

Thanks !

Whatever the sticker on the driver's door jamb says.

I run mine at 32 cold, which is what the sticker on mine says.

X2, whatever the sticker says. 26 lbs. is too low.

Thanks guys ! That's what I thought .

My door sticker says 30psi , so that's where I'll keep them .

I appreciate the input .

I have the exact same tires. My door jam on my 13 GS says 30psi but that is based on OEM tires. Non run flats don't have as stiff sidewalls. I run mine at 32psi and with over 5k miles on them the tread wear is even across the tread.

In Utah the tire pressure monitor likes to read about 10% low anyways so it usually reads 27psi. Colder temperatures would cause the warning light to go off.

I did run them at 30psi in the beginning and it felt too soft.

That too , is really good information ... Thank You !

Maybe I'll try em at 32psi as well ...

26 psi cold seems ridiculously low. There was a post a few months back where I believe the guy had your same tires and the tire dealer was recommending 35 psi! I'd run them in a range of 30 to 32 depending on your driving habits and personal preferences.

Thanks for all the input guys !

I'm going for a cruise today ( it's BEAUTIFUL in Chicagoland !! ) and I'll bump up the pressures in my Super Sports to 32psi , and see how they feel !
