Hi guys, may I know e tyres pressure for tyre's profile of 225/45/r17.

Check the guidelines on your driver's door.

The guidelines Tyre's pressure indicated:

Front:220

Rear: 210

 

But my car comes with only 15 inches rim (stock).

I had changed to 17 inches so just wonder if I need to increase/decrease on e pressure of e tyres.

You can try higher tyre pressure,i put 40psi for my Z,i felt the car is sharper & better economy than the 35psi spec on the car manual.

What tyres are you using?

Probably your sidewall is too soft? What tyres are you using anyway?

I also pump 10% more than the recommended pressure when cold.

[GoodCar]

Plus 10 percent from the recommendation will save a lot of fuel.

But make sure you know what you are doing,

 

If you pump too high when unladen and later on the full laden weight cause pressure greater than max tyre pressure,

A potential hazard present.

[Monoswift]

is 10% consider too much or is it still acceptable?

 

my 15" manual recommend 230 but i upsize to 205/45/16 i just fill about 5% more when cold..

Sorry do not get what you mean.

Though my stock rim is 15 inches, I changed it to 17 inches e moment it with me.

 

So powerful or not, it quite e same for me.

Am more concern on e grip of it and too believes getting e right tyre pressure will increase e life-span of e tyres.

[Jchuacl]

Sidewall for this tyre is a bit soft, you can try 240/230 for a start.

 

Just changed to PS3.

 

[Dh15]

I pump 270 for all 4 tires.
