How much PSI do you think is the best for your performance, tire wear and gas mileage?

I know factory recommend our coupe to set it at 35 psi but i just want to see what is with rest of driver's option. Especially with after market 19" & 20".

 

i have the oem 19"...i try to keep the tires at 35, check it once a week and you should get max tire life.....

I think checking AND maintaining the recommended psi is the best way to get good gas mileage and tire life, I did this with my 99 Prelude and my tires look near new and they are the original tires....though I only have 50,000 kilometers on em, My wife's 03 MPV's tires look like they only have 50% tread left and they only have about 25,000 kilometers on them....hate to say it but my wife checks the tires like once a month...maybe .........I guess I will check it out weekly for her

Buy yourself a digital tire guage and save $$$$, check weekly and save $$$

 

Pre Sentance Investigation?

 

I have 19" GTC's and I run 40 psi. Seems to wear a little better.

 

FILL WITH NITROGEN!!!!!!

 

You can't lose by staying with the manufacturer's recommendation...he has done all the 'legwork' on performance, longevity, gas mileage, and comfort.

Having said that, I set my Coupe tires at 37 cold. I don't mind a little extra firmness in the ride and felt it helped wear and tear a little.

Be sure to set the pressures when the tires are cold tho, or you'll overinflate them.

35 always

 

i run 40psi on my challenges w/ toyos

 

I did that and got excessive center wear on my toyos. Returning to 35 psi

 

I got aftermarket 19s on my '04 6MT. Talked with the tire techs at my local tire chain. Probably the best thing you can do is to fill the tires with nitrogen (less prone to temp changes) and since I upsized my wheels/tires, he recommended that I run my psi a bit higher for two reasons:

1. Compensate for the lower profile to better protect the wheel from bumps and potholes.

2. Stiffer sidewalls with less lateral movement to increase road handling characteristics.

We came up with 37 psi as a compromise. Pretty happy with this setting. BTW, I'm rolling on Michelin Pilot Sport PS2s. 245/35/19, 275/35/19

 

Currently running 42 PSI all around. Im achieving the best mileage Ive ever seen in this car. Could be also helped by the fact that I switched to Full synthetic as well.

 

Careful not to go too hard.......The contact patch will decrease affecting traction including braking......
