I was wondering what psi i should have my tires at? The wheels go to a max of 51 psi and the recommended psi for it is 32 front and 29 rear, That is almost half of the max and makes it feel almost flat when driving and hard to steer with passengers? Any recommended psi levels you guys enjoy for all around handling and performance?

 

That seems a little odd that factory specs would have the rear a little lower then the front. Where did you find this info at. I have no tC so I cant just find this info easy. You should have this little sticker on the driver side door. It should say a good deal of info along with the PSI for the tires along with the spare.

 

Always, always ALWAYS, use the pressure specified by the manufacturer.

If you under or overinflate, bad things can happen, including voided warranties, accidents, and your insurance company telling you you're SOL.

Glad to help.

Chucksu, it's not uncommon to have different psi for front and rear. My Saturn has 30 for front, 26 for rear. I would imagine it's to compensate for engine weight.

 

what if you get aftermarket rims and new tires... would the PSI stay the same?

sorri if stupid quesiton

 

Not a stupid question, and no, if you go from 17s to 18s, 19s, 20s, whatever, the amount of pressure you run in the tires should typically go up as size increases. I found this at http://www.DiscountTireDirect.com :

 

yup, that's the correct info on that little sticker on the driver's side door, 32 front and 29 rear. my question is...how precise should you be? does it matter if the front is 31.5 and the back is 29.5? should I get a digital meter to check it or is an analog one ok?

 

No, dial meters are better. Digital and pencil-style gauges don't work as well. It doesn't matter if your tire pressures are off from the factory specs by a few pounds. Essentially, you want the fronts a little higher than the rears, since most of the weight is in the front. You want each of the fronts to have the same pressure, and each of the rears to have the same pressure. Higher pressures will give you better economy, lower pressures will give you a little more "bite". To counteract some of the understeer in the tC you could run the rears a little higher than stock, and drop the fronts a little. Keep in mind, pressures lower than stock will increase your chances of damaging a wheel.

 

Yeah, keep the 32 front/29 back. I went about 5 weeks without checking and it had already dropped about 3-4 PSI in each tire. However, I think I am going to try on the first set of tires to NOT have them rotated on every other oil change. I have also followed this on my other cars but after listening to the guys on "CarTalk", they recommended the savings on rotation does NOT match the savings on tire wear.

i remember reading in the manual that if you plan on going more than 100 mph in legal places they recommend having your tires 38 front 31 rear. thats what i have it in. Should i increase the back more?

 

"they recommended the savings on rotation does NOT match the savings on tire wear. "


it's required for the tire warranty though.

 

Anybody who pays to have their tires rotated is a sucker. It's just about the easiest thing you can do yourself, in some respects easier than changing your oil.

 

what level tire pressure do the majority of you people have in your tires?

 

32 front, 29 rear with the stock wheels and tires.

 

i did try 32 all around.. rear tires began wearing quickly.. since there isn't a lot of weight in the back to push the tires flat.. wearing the centers of the tires.. i put it back to 29 and yup.. wearing correctly now..

 

I could have swore that someone (possibly the dealer) said the tC had a tire pressure monitor. I didn't think it did, but does it?

http://Quoted from <a href="http://w... halfway down.

 

It does, it uses the ABS system to see which wheel spins slower/faster than the rest. It does not tell you which wheel is off, and it doesn't tell you the PSI.

 

It does....and it's bugging the hell out of me! https://www.scionlife.com/forums/viewtopic.php?t=28255

 

Oh. I thought when it said tire pressure monitor it would be like my mother-in-laws Chrysler 300M, where it displays the actual pressure for each tire on a display. This one seems kinda lame.

Thanks for the link, Russian.

 

Well your mother-in-laws 300M was also twice as much as the tC so... this system suits me fine.

 

Punk:
That's true. I guess I just made the mistake of assuming all tire pressure monitors were the same. I would much rather have something tell me when my tires were low then not at all.
