Toyo 205/45 ZR16 air pressure

[schutzenfester]

I have a 2007 Fit with Honda factory 16" spoke rims with Toyo 205/45 ZR16 87w tires. (Proexes F24 PXF24)

Sidewall states 50 psi max. I know that is not the ideal pressure but the manual states pressure for stock tires that did not come with my new Fit when I bought the car.

Any suggestions for proper psi inflation?

Thanks in advance for your feedback!

I will say 33 or 34 psi

i think it kinda depends. If you want better handling feel, and possibly better mileage, you could do about 40 ish. you'll sacrifice comfort though. rvall004 said 33-34psi , which is probably a good balance.

for a car of this weight, 33-35 should be plenty....

but if you have the garbage ziex912's like i do, pump it
up to 38-39psi. it feels so much better.

uhhh, IIRC the factory Honda rims are 15".

are you talking the HFP wheels?

Either way, I do 35psi in all my cars for the street. Maximizes fuel economy without threatening wet-weather traction. Going beyond 35psi on most street tires will cause more possibly hydroplaning issues....and 35psi+ means less contact patch on the ground, so the handling won't be as crisp.

for your tires maybe... but tires are all different and depending on the
application higher psi is recommended. but beyond 40psi is kinda iffy...
but those hyper milers use those crazy 50psi setup. well, kinda
crazy in my books but works for them.

tires are all different, yes. But in general, with cars, you shouldn't exceed 35psi, or your hydroplaning possibilities increase. There's an equation we used to use when I was in flight school to determine at what speed a tire has the most chance of hydroplaning, based on PSI. I'd have to look it up.

Beyond 35psi you're just trying to increase mileage, at risk of uneven wear and wet weather traction loss.

yea i'd go with 32-35psi to keep it safe
