Hankook Ventus v12 Evo2 Tire Pressure
 

hi all,

currently i am running hankook ventus v12 evo2 tires (235/40R/18) on wedssport tc105n wheel (18x8), and the tire press was set ~34 psi but car tire pressure gage is showing low tire pressure.

was wondering anyone running a similar setup and or know what's the ideal tire pressure for this setup?

Tire pressure sensor light is on because one tire is lower than the others.
There is NO ideal pressure for every setup and driving condition. 30-36 is a good starting point for most cars.

Did you swap tpms?

i checked all tires, and they are all around 34-35 psi

no i did not, all i did is swap wheels and tires

i saw some people running 36-38 psi on 18 inch wheels, not sure if that's better?

Thats the problem mate, you need to swap old tpms from your stock wheels to the new one

Definitely the problem. Also to be noted if you DO end up putting TPMS on the Weds... You mentioned all tires were 34-35psi. Subaru TPMS is suuuper touchy, so set the pressures when they're cold and make sure they're ALL 34 or ALL 35. One tire being a pound off can light up the TPMS. Carries over from the AWD cars where that's a bigger deal because of tire diameter having an effect on center diffs.

Do I need to get a new tpms for the weds? Cause it doesn't come with one.

Swap the original tpms to weds
