So since most of you guys if not all have been in the fitment/stance game longer than me, I was wondering what should be PSI be to keep the tire from unbeading, coming undone etc etc. Planning to put some 205/40 on a 9. Any other information helps I can update this with a list so newer people will know.

Just need to make sure I can make it WFC meet and back in one piece. :lol:

It's basically the same as normal tires dude.

I run 38-40 in mine 225/35 on a 10 and I've never had any leakage. (38-40 for the gas mileage lol)

Best tool, get a digital tire pressure gauge. Just check on them every so often, don't want to run flat.

hope that helps...

That factory recommend but since we stretch so we need a bit more PSI to hold the tires in place.

I seem alot of stretch and for a mint stretch is 38-40 psi, for extreme stretch and 35 series tires is 42 - 44 to protect ur wheels.

I seem super VIP stretch running at 55 - 60 psi but like extreme extreme stretch lol.


I personally run somewhere at 38 - 44 psi and no complaint (8.5 with 215/35, 10 with 235/35)

Yea, I think Im gonna run 38-40.

32 PSI is enough to keep the bead in place no problem.

even on a 205/40 on a 9? wouldnt you run a little more to be on the safe side?

I run 42-44 psi, as long as you arent getting near the max limit of the tire then it doesn't hurt to run that. Plus a lot of the tires like Falkens, Federals, Suhmitos, etc that people tend to stretch has a soft side wall so the stretch with higher psi makes the sidewall a bit more rigid.

For stretched tires not to un-bead just make sure u stay on the high side of the psi, I usually run 38-40psi on a 215/40/18 tire on 9.5" wide rim and drive 100+ daily and not one problem yet.

i honestly think once the bead is set i dont think it will come undone... unless you have an extreme tire stretch running like 20PSI... im running 225/40 on a 9 with around 32-40 psi same with my rears 235/40 on a 10

upper 30s / low 40s seems to be the general consensus. I fill it to around 42 and refill months later when it drops to around 35.
i read somewhere vehicle manufacturer recommended PSI is lower for better ride comfort, but higher PSI gets better MPG.

Some of the sizes and widths posted don't sound like the tires are being stretched . I run a 195/45 on a 9 with 40 psi . The psi from the factory on my car is like 30-32psi ,in my car such a low pressure causes the car to handle not so good . I've stretched 205's on 10.5s an 235's on 12's with these setups i usually put in about 45-50 psi just to be safe .

grippymonkey
12-10-2012, 07:11 PM
My rule of thumb is that if the tire took a bead blaster to get it on then you need to be running around 40 or close to Max PSI. I would rather be safe than sorry. I popped a bead on a small crack in the track drifting my E30. I was only a little down on the PSI. I've drifted that same setup a million times with proper air and never had an issue.

Just out of curiosity- do you remember what tire, wheel size, and if it was close to max psi when this happened?

Thats a super mellow stretch. You can probably get away with 32psi all day, but I'd bump up to about 35-40 for peace of mind.

Ok everyone, so here's what happened. I have a 245/40/18 on an 18x11. Hasn't given me any trouble over the year + that I've had them mounted. I go out Monday night, checked my PSI and all tires were around 40-42 psi. Everything was fine. I wake up the next morning and the tire bead unseated on the front of the wheel. I was like wtf?? Took it to a tire shop today and had a buddy refill it with air and the tire beaded right back up. Checked for leaks, none.

So, has this happened to anyone else before? Should I up the psi a little more to make sure it doesn't happen again?

Ok so I took my wheels back to my boys shop to seal them with bead sealer and they're still leaking a hell of a lot. We checked the leak and it's coming from where the bead sits. Anyone have any ideas on what I can do to fix this (other than buy new tires...)? I plan to sell the wheels soon so I'd like them to be leaking less

Did you check the bead itself? Might have a small tear in it causing it to leak so much.

Wirtz
09-27-2013, 04:28 AM
Maybe because you're running a retarded amount of stretch for your setup and the tire doesn't even meet the barrel? I can't imagine that sealing well consistently

SpyderGT
09-27-2013, 06:26 AM
We checked out the rim and tire, they looked good. It's probably too much stretch but it's weird cause one leaks way more than the other one? Is there no way to ensure a good seal?

Ya. Let it reach both barrels and your seal will hold much better

There is nothing to support that side wall location so when you turn and shit it all flexes and loses air and stresses the bead

SpyderGT
09-27-2013, 09:30 AM
I lose most of the air while I let it sit. When driving it barely drops but now with the weather getting colder is leaking way more when letting it sit. I'm going back in on Monday to give it another shot

Just a general question, i'm on the fence about stretching Hankook Ventus V12's 215/40 on 9.5's (4), or just go Nankang NS2's 215/40 on 9.5's (4)

(Keep in mind I already have (2) Hankook Ventus V12's 215/40 from my previous setup)

Are the Hankooks a better choice for stretching compared to Nankangs in relevance to being able to withstand daily driven stretch or are they relatively equal?

In the end should I buy another 2 Hankooks, or just buy 4 NS2's
