What is the recommended PSI for everyday use on these tires?(245/35R19 and 275/35R19)

 

Ask Wld350Z - he has same..

Cheers Amy -

 

wouldnt you use the nissan specs still?

 

Depends on the rims.. But 35 Psi is a darn good place to start.

Keep the TPS senders.

I want to know too. I have mine about 37 psi cold. Thinking about bumping that up to around 40 psi.

 

I have 36 front 34 rear. I'll lower rears to probably 29 for autox to get the best performance, but since I want to get some miles out of tires, I keep 34 for the road.

 

If you are running larger than the OE size, usually you can bump the psi up a couple. For instance I am running 245-40-18 at 37 and the OE 245/35/17 were 34 & 32 (02 Audi Avant). Questions, e-mail me at youngc@toyotires.com.....I am not on the board that often so e-mail might be better.

 

so 19's you recomend around 40?

 

I would say at least 37 and then see if they wear evenly. If you start to get edge wear, you might bump them up a little.

 

Man, I was running mine with too little air I guess. I was around 34, maybe I will step it up a bit whenever I can get my rims back (sigh) and put the Toyos back on. I am worried that they would be too rough and bouncy at 37 psi though, cause the Z has a tendency to be bouncy anyway.

 

I would try increasing them to at least 35-36 and see what the ride is like. I run mine at 36-37 (of course it is not a Z) on a set of 245/40/18 and they react well and are not too stiff. Again, just keep an eye on the tread wear and if you are getting edge wear, you need to increase the pressure, if the centers are wearing faster, decrease the pressure.

 

I have the same set up. I run about 35-36 in the winter. In the summer I start at about 34-35 because once I drive a little the pressure goes to about 36-38. Only a little difference in the ride, not to obvious. So far tire wear is pretty even at 7000k miles.

 

cold: 33-34
hot: 36-37

that should be fine..
