25-28 is alittle low, 32 PSI is average. I run 35PSI on my toyo proxes. 30-40 is perfectly acceptable.

I keep my tires at around 32 PSI. I think 50 PSI is pretty high for daily driving. Your gonna wear out your tires pretty fast.

Keep it at 30. It will raise up once the tires are warmed up.

over inflated tires will wear faster in the middle on the tire. under inflated will wear faster on the edges. 30-40 will wear evenly.

If you have stock tires, or equivalent to stock tires, run any where between 28 and 32 is good.

40 is way too much pressure. Always look at the recommend tire pressure on the door, and not the max psi on the sidewall of the tire.

btw, you can't look at the tire and say "my tires look underflated", unless they are actually flat (in my terms, like 10 psi or less). I guarantee you that most people could not tell a tire that had 25 psi from a tire with 35 psi.

Just run you falkens at 30 psi. I would never run a tire on a civic more than 35 psi.

With 30 psi, on warm days psi will go up to around 33 psi maybe a little more, and on colder days it'll go down to like 28psi.

I don't where you noobs get your info from. Running 40 psi on a civic, LMAO.

It says 50 psi on the tire, cause that's the max psi. Just remember, a tire can go on many different cars. Different cars have different psi ratings, and load index's.

Alrite,
this is word for word from a Honda Tuning Magazine (June/July 2002 issue):

The rule is:

(Vehicle Weight in lb/100) + 2 psi at heavier end + 2 psi all around if suspension and alignment are stock.

Example: Stock Honda S2000, 2,800 lb.

(2800/100) = 28 psi
Add 2 psi all around = 30 psi
Add 2 psi to heavy end = 32 psi rear

*With modified suspension, the result is 28 psi front, 30 psi rear.

Hope this helps.

I run mine always from 32-35. 28 PSI is a little low. In the summer u can actually put the tires to 32psi and in the winter u can put it up around 35 because in the summer it is hot and tires expands when it gets hot so it will build PSI. In the winter for every 0 degrees or something it will drop like 4 psi. Somewhat like that and i can't remember. So yeah. If it says like max 51 u can put around 35-38 but usually 38 psi all around is good. If your max tire says 35 then put it on 32. If it says 44 i usually put it on 25. U can follow your spec for the car. It should tell u on the door or open the glove box what psi u should put on your car.

Actually, you should put less psi in the winter. You want more traction, and a lower psi will do that for you. More traction = Better control of your car.
