well jus wanted to share with u guys....i posted this thread in the tire and wheel section no response...maybe u guys can help

"what should my tire pressure be? 18' (wheels are called stern i think)
plus i'm rim babysitting LOL....

but heres the new shoes if your too lazy to clip on the link above...

 

i can't answer your question, but looks real good man. love the lip, really sets it off. nice choice..im getting some wheels tomarrow, look out for pics in member's rides forum guys!

also what are you lowered on?

 

read the tire should be on there.
4 lug

 

5 lug man...our cars don't fit 4 lug ROFL!!!

 

I know but it looks like 4 lug in this pic,

I see what I thought I saw yea. . . . . . nice wheels very shinny. Whats up with the orange corners?

 

that dont look 4 lug...

 

I keep my tires at 40psi. I have 18s with 235-40 tires.

Wheels look pretty good, look like HRE knock wanna bes tho. what size tires do you have?

 

normal is 35 psi.

 

isn't 40psi a little much?

 

I use to keep it at 35 until a lot of people told me that it should be kept between 40-45psi. 45 seams way too high, but honestly I have no idea what to keep it at because everyone tells me something different.

 

it says on the tire itself that 45psi is the maximum. I still keep mine around 32psi. You might want to get the exact psi reading; too much air will blow the tires.

 

ahhhhhh that looks great and dont get clear corners!

 

stock 15" is 29 psi.

so aftermarket 18" should be at 32 psi (+3 psi).

 

in addition, if u are running higher psi, u will get better gas mileage, but handling ability will decrease.

 

K, thanks guys, I will deffinately lower it.

 

my max tire pressure is 50 psi (cold). it says it right on the tire n not to exceed it. so my front is 44psi, n back is 42 psi. 32 is too low n you'll go through tires quicker than being at 42 psi. yes its true that handling wont' be as good, so then just slow down 5 mph on each turn. it can save up to 4 months of more tire. which is a lot considering 18" tires are kinda expensive

thnks guys for the input on the tire pressure!

whats wrong with orange corners?

 

i am like ImmaSquashYou. i keep my psi around ~44 and i am on 19's.

-myke

 

Read the tire, it is your best bet. I keep my 15" hubbies at 35 PSI all around.

 

nothing is wrong with the orange corners, it looks JDM!

 

I dont know what you guys are smokin but it's not the psi rating of the tire that is as important as the kind of vehicle it is going on. All sedans should run their tires at 30-32 psi. Vans and SUVs at 35-40 psi...and really large trucks, etc... you fill to a happy medium below the max psi rating for the tire (for example if the tire's rating is 80 psi (large Load E rated tires for industrial applications, etc..) you fill it at 65-70 psi). If you're loading your max with 40-45 psi you're asking for a blowout. Most tires for our cars are rated at 45 psi MAX so if you hit a bump too hard or something that pressure is going to go up due to the deflection of the wall of the tire and you risk having a very bad day. I work in a shop as an automotive tech so changing/repairing tires is something I do 55 hours a week for a living

 

he's absolutely correct. I work as a tire tech. and we always check the psi of the vehicle, not the tire. 35 would be correct. I dont see the harm in a little higher, but 44 seems rediculous, seeing as how we hardly fill up to 45 on most suv's. i cant imagine that does much for your ride quality either.

 

It's one of the first things i learned on the org. Mine is kept around 32-33 psi religiously.

 

Chillin and Nismo thanks for the support It's sad that there is so much incorrect info floatin around

 

Looks good.

 

rims look nice, all you need is a nice cf lip!!

btw when i put too much psi, and hit a bump i always get them dam titi things on my tire.

i didnt know more psi equals better gas? im about to fill them suckers up then!

 

wtf is "titi things"
and i dont know if the theory is "more psi equals better gas mileage". but LESS psi will cause worse gas mileage. you dont want to go over fill your tires.
just keep it at 35.

 

Wrong. More PSI means less sidewall flex which equals better handling. What does suffer however is straight-line traction.

 

dam my tires are dam flat kind of.. i have those lumps on it... you know those things that look like tities

 

Lol.. funniest thing I’ve read in a long time!!

You have a bubble in your tire, so unless your suicidal you need to replace those tires with bubbles.. asap.

 

i'm running 38psi up front and 35 in the rears.. 235-40-18

 

Your tires need to be replaced even if they only have 1 lump on them. Those lumps...or "*******" as they've been referred to on here...are caused by that being a soft or weak point in the tire. This is a safety hazard as it is weaker than the rest of the tire and has the potential to blowout. And remember...32 psi all around is what you should be running in your tires on your max

 

1. Less PSI means a wider contact patch, which means more traction and sometimes more grip. More PSI means less sidewall flex, which means quicker response and more stability. Each hurts/helps handling in a different way, so you can't say that more or less PSI is universally good or bad.

2. Yes, running a tire at its maximum rated pressure is bad. But, running a squishy low-profile tire could cause rim damage when you hit a bump. Since bigger rims are heavier, hitting bumps or potholes will cause much harsher impacts. With a low-profile tire, there's also less rubber to cushion the impact. For those reasons, big rims with low-pro tires need higher pressures to prevent rim damage. That's why it's not accurate to say you should always inflate your tires to vehicle spec, or that they should always be within "the range" for road cars, etc., regardless of size.

Also, while the tire techs here express alarm at using 40+ PSI in a road car when that's typically SUV territory, you have to keep in mind that SUVs have MUCH higher profile tires than what we're dealing with here, so there's much more cushioning to prevent rim damage.
