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

 

factory says
33 Front
30 Rear

 

yah, factory usually goes for comfort so the psi ratings are lower.

 

The wheels and tires on the Honda Fit come in three flavors…

The 14-inch Standard model…
The 15-inch Sport model…
And the 16-inch Accessory Performance model…

Your allusion to lower inflation pressures for less road noise and softer ride end at the 14-inch Standard wheels. You still have the Sport wheels and then the 16-inch performance wheels…as this thread is about. The performance engineers (the same guys that do all the factory racing) at Honda say to use 33 F and 30 R. For people like you, the placard in the driver’s door jamb shows 33-psi for the 16-inch accessory wheels. To get the best performance out of your 16-inch wheels, follow the advice of the performance engineers…just my 2¢.

 

well, we like to take the cars up a little from your next door neighbor's
mom's grocery getter setup. therefore, we tune our own psi's by experiments.

but i suppose if you think the junk a/s tires the car comes with is wat
the performance engineers wanted you to use for performance
be my guest.

 

Wow! I’m impressed! Please forgive my ignorance. I didn’t realize that you were a scientist able to document the results of you experiments. Please share your test conditions with your pyrometer readings. We could all benefit from that kind of information/data.

 

I have a 2007 Fit Sport; the factory reccomended air pressure (marked clearly on the side of the driver side door sill) is 32PSI front and back.

The Engineers at Honda have deemed this pressure to be the safest combination of comfort, traction, fuel efficency and responce on a stock size tire that came with your car. Brand of the tire is not a consideration. Also be aware this is a cold PSI, only measure and fill your tires when you have not dirven the car.

The only time you should be making slight adjustments to the pressure is if you have choosen a wider or more narrow tire size, and even then only by a couple of pounds maximum. Other exceptions to the rule would be if you are on a closed race course you may want to increase pressure by as much as 10psi, also if you are in a blizzard with ice and snow it would be prudent to reduce the pressure by a couple of pounds.

So regardless of all the reccomendations of people who think they know better I would suggest following what pressure is reccomended on your driver side door sill.

(Appologies if this is a bit pointed btw, I have been trying to argue this point with people who have been trying to justify running more than sidewall max in thier tires (this is the engineered maximum for the tire) for the sole purpose of getting a couple extra MPG at the expense of safety for themselves and others... these are also the same people who turn thier car off for brief periods on the highway.... *shakes head*)

 

At least you are reading some of the provided information….
This thread is about the optional 16-inch wheels with the optional 205/45ZR16 tires. If you would buy the whole set of 4 wheels from Honda, you would get a replacement placard for your door jamb. And as I has stated earlier, the engineers and the placard say 33-psi. As you had stated, 32 is the recommended pressure for the 15-inch wheels with 195/55R15 tires. Since I never had 14-inch wheels on my Fit, I don’t know what the recommended tire pressures are. I guess I could RTFM, but I’m not interested in the 14-inchers and this thread is about the 205/45ZR16s.

 

i dont just think i know better. i do... from experience.

engineers you talk about are going by general terms for the general public
using the tires their commodity mangers chose based on price. im not
going to be happy at all with that kind of low level setting.


yah, those eco-MPG guys are pretty crazy to run 50psi and 200psi
on their donuts.

 

bringing an old thread back in honor of the Walking Dead premiere tonight:

So I have the wider 205 tires on my stock sport wheels and have been trying to find an ideal number for the general g-max tires I have on them.....I tried 42 but in NYC that is jarring when combined with Swifts...

now I'm trying to deal with a squirrelly feeling I'm getting from the driver side on shitty roads and lowered it to 36 al around.....will lower pressure help deal of increase this problem....also wouldnt wider tires need higher pressure when coupled with sport wheels?

Thanks!

 

Lowering pressure will help with the ride some. 36 psi is fine.
