...without loosing comfort. What do you prefer?
I found that recomended pressure on front wheels makes them look a bit flatened

 

I run my tires at around 35 psi all around. I'm on stock sawblades with a TOYO TPT tire.

 

Yes, the fronts will always be deformed a little more due to the front-heavy weigh distribution of the car. The front should be 2-3psi more than the rear - not more than that.

The recommended pressure should be around 32/30 (f/r) psi, but you can push that up to 40/38 or so and still not be uncomfortable. I would recommend under 35 unless the bulk of your travel is on smooth highways.

In the end, you'll find almost no measurable savings in fuel economy. The real fuel economy savings is when you start with underinflated tires and bring them up to proper pressure.

higher psi >> better gas mileage, more uncomfortable, decrease in handling, increase in power
lower psi >> worse gas mileage, more comfertable, increase in handling, lose in power

stock spec for 17" is 32psi all around... i have mine @ 35psi. i forgot the stock spec for 15", i suppose it's 30psi? maybe u should try 33psi and see wat will happen...

 

will try thanks

 

lol.. i must be out of date....

I run 30psi front & 28psi rear.

Also my 17"s are 14.3 lbs a piece so if they get any more psi the tire jumps every bump...imo

 

under the arm rest in the car, it recommends 33F 32R.

I run 36F 34R, I get great gas milage with that setup.

 

35 psi for rear and front

 

in your armrest it says 29psi front and rear..

 

run the recommended pressure of the car.
dont max your tires out, use common sense.
keep it 32~35.

 

the tire tends to bow out at higher than reccomended psi causing horrid tread wear (center wear only). try 35/33 and remember to adjust based on outdoor temperature, it makes a difference.

 

My father-in-law did extensive testing with tire PSI on his 94 max. He's a tight wade like that. He found out the optimal PSI is 32. He said after 32 it didn't make as much difference and also you have less contact with the road.
