OEM tire psi same as aftermarket tire psi?

**wiretap_md** · June 2nd, 2003 10:33 PM

Take my case as an example:

OEM tire dimensions for the Suzuki Vitara is 205/70R15. The recommended tire pressure as stated in the door sticker is 23 psi front and 23 psi rear.

I changed my tires 2 years ago to BF Goodrich T/A All terrain 235/75R15. Are the OEM tire pressures still applicable to my current tires? Currently, they are at 28psi cold for both front and rear.

AFAIK, same lang ang tire pressure even if you changed to a wider and taller tire. Maybe Suzuki wanted to maintain the soft plush ride kaya nila pinalalagay sa low pressure ang hangin. Believe it, even if I have 33 inch tires on my ride, we have the same tire pressure.

I use the same prssure with all my tires. 31x10.5, 32x11.5 and 275/70

curious lang..

I'm running now at 25psi. Adjusted it early this am before leaving for PGH. Syet! Grabe ang improvement ng ride. Di na matagtag and "damp" na ang feeling. Tried doing hard braking and cornering. Same pa din ang performance. I think I'm sticking to 25psi for the meantime.

yan yung manufacturer's specs. para akong nakasakay sa truck pag yan ang sundan ko. ginawa ko kasi 29 - 32, di pa rin gaano comfortable. binaba pa namin ni freeman kahapon to 29 - 30. mas ok ng konti. pwde kaya 28-28?
