I had four T1R's put on the car and Firestone inflated them to 35 PSI.

This obviously wasn't enough because the tire pressure warning kept coming on.

Anybody else have these and what pressure are you running? I see the maximum is 50 PSI, I am running 40 PSI right now.

Thanks.

 

I am running Toyo T1-R's in stock sizes (225/40/19, 245/40/19) and use 35psi cold. I have had no issues at all with the warning. Maybe Firestone damages your TPS.

 

i have TOYO T1R's 245/40/19 front and rear on stock 19's... 35psi and no issues at all

 

Hmmnn, that's odd. Maybe they were slightly under 35 PSI.

Anyhow, they seem to be OK with 40 PSI, that should not hurt anything.

Almost time for the Blizzac's anyhow
