My dealer says the tire pressure on my Goodyear RSA (factory) should be 32psi, but on the sticker on the car it says the pressure should be 30psi. Anyone know what it actually should be ?

 

I would follow the sticker first. Raising the pressure a little (2 lbs) won't hurt anything, you may see a small increase in mileage but you may also notice a small degradation in the ride quality but I would be surprised since it's such a small difference. I run 32 lbs in my aftermarket 18" wheels with 245/45/18 tires.

 

I would run what ever the sticker on your vehicle tells you to. Although it
does seem a little soft because I run 37 lbs in my tires and the local tire shop
tried to tell me I should run 40 lbs....I tried and tires were rock solid....not a
good thing for a comfortable ride. Keep an eye on your tred so that the
outside edges don't start showing excessive wear.

 

Anything between 30-33PSI is fine on a cold tire. Thats how I have been running mine for years on all my cars.

 

The idiots at the dealership delivered mine with 44 PSI. I lost three fillings from my teeth on the way home it rode so rough!

 

I run mine at 35psi cold but those are wider 20" tires so 32-35 should be perfect for yours.

 

Yeah, play around with pressures in the 32-35 range and see what you like best. On the sport models with the stock 18's, the suggested pressure is 33psi...
