Hey I was just wondering what is the tire pressure suppose to be set at for 19" tires. I have a set of 19" toyos by the way. Thanx in advance.

 

I have mine at 34 psi. Some go higher for fear of potholes.

 

On coupe, Im using 36.5psi at 80F+ cold right now.

If below 65F, I use 38psi

 

hey guys thanx for the feedback, especially kenchan, You've been really helpful.

 

These suggestions for any size 19 inch wheel? I'm running 245/35/19 and 285/35/19 Falkens.

 

hmm... Tire presure is whatever your car's recommendation is. It doesn't matter if you have 17 inch rims or 20's. It will remain the same.

 

Low profile high performance tires that didn't come with the car does not use the listed air pressure. 17's with the same aspect ratio, yes, would be the same as 19's. A tire with 35 profile needs more air than 45 profile. You will have uneven/premature tire wear if you don't have enough air in a low profile tire. I've learned this through trial and error. I'm older than most guys around here. I've been using performance tires over 20 years. A lot of shops told me I was crazy years ago but most now totally agree with this. In the winter I use 38-39 psi. In the summer it's 36.

 

I'll take your word for it. What I stated above is what the shops told me over the past few years.

With my 285/30/20 my tire wear was even, I had it at 35lbs (in california, so we don't have winter here). Only thing was hot was my creditcard account replacing those tires.
