stretched tires and safety... fact vs myth

[kalypso123]

this may seem like a dumb question, but I dont think it is.

once stretched tires are fitted with adequate pressure, lets say a 215, on a 17x9, and your wheel has a proper well

Is there any risk from running stretched tires?

[90KAcoupe]

i may be wrong but the drop-center (what your calling the well) has nothing to with stretched tires.. if anything the size of the bead matting surface would be more important.

lmfao that is not a wheel well,its drop center.

This is a wheel well

BTW, in answer to your question, running stretched tires raises the probability of breaking the bead when your tire goes flat. I would say that yes, it is slightly more dangerous.

[kalypso123]

Thank you redsx13... that exactly what I was looking for

and also, appreciate the help from everyone.

I did search, fuck off

[aznpoopy]

with adequate pressure, i doubt it.

without adequate pressure, the tire *will sheer from stress at the sidewall. ask me how i know.

[gotta240]

How do you know?

[Otto347]

I did search, fuck off :bowrofl::bowrofl: Bullshit, see attached pictar!

Theres 3 whole pages of tire stretching threads.

been running stretched tires for 3+ year now, i have gone as far as a 225/40/18 on a x12.. tire would leak air ever so slowly but never had any probs running a fatty stretch.

[kalypso123]

from being at full pressure how long did it take to get to 90%

[aznpoopy]

How do you know?

maybe two years ago, i was a dumbfuck and didn't recheck tire pressure after a big and sudden drop in temps. tires were probably overdue for pressure check way before that. stretch was nothing... only a 225 on a 9" wheel.

the sidewall ripped apart while i was driving on the highway. luckily i felt the vibration about 20 seconds before it happened and decided to pull over. it fully came apart just as i was coasting down... probably going like 20mph at that point.

after the fact, i could see similar wear on the three other tires. i had them all replaced. sidewall rip basically went all around the wheel, except for a little bit. if it hadn't stayed together i'd have been driving on the wheel rim.

so yeah. if you live in a place where it gets cold, don't be stupid like me and let your tires get underinflated. it's mildy bad for normal tires. but could be catastrophic for stretched ones.

[kalypso123]

aight... thanks everyone im satisfied

215 40 on a 9 is real tame anyways so go for it

over 9000 accidents every year due to stretched tires

I doubt it's much safer to stretch onto a wheel with a small drop center.

But, it is easier to seat the bead on a wheel that has a one.

I have a 215/40 Toyo Proxes 4's on 17x9.5's and they have a big drop center (the less ideal looking wheel) and I haven't died yet. Just takes more pressure in the cheetah to seat the bead. I run max pressure in them. Never had a problem.

not really,

a small drop center doesn't make it easier to seat the bead, to seat the bead you just inflate the tire. it just makes tires a bitch to take on and off.

[MisawaJason]

215 on a 9 isnt bad at all. you should have zero problems running that setup. Disregard all the dumb posts man

85% on zilvia. Although some people on this site really do know what they're talking about

[aoiken3]

85% on zilvia. Although some people on this site really do know what they're talking about

and the 15% who really know their stuff account for probably 5% of zilvia.

yeah check wikipedia it says so

so don't do it. put 255's on your 17x7 +40's!

no, not really i want to see that shit on myth busters. :fruit:

Wrong. Have you ever mounted a tire?

http://i39.tinypic.com/25evaf4.jpg

Let's say the red is where the tire sits, which wouldn't be in real life. But it works for this.

To get that tire to air up, you need to stop all the escaping air. Technically the drop center isn't what's making seating a stretched tire easier, it's the wheel design. But, if the wheel has a big enough drop center, it won't be ideal. So they're related.

The wheel on the left has a BIG drop center, so when you try to air up the tire, all the air will escape. Even with the bead blaster on the tire machine. Especially if the tire has a stiff sidewall, there's now way you could mount that tire without a cheetah/ fire/ some other trick. If you move the tire in either direction, the opposite side will have a HUGE gao where air will escape.

The wheel on the right has a small drop center, Which leaves a lot less space for air to escape from. If you move the tire over to the right, it will close the major gaps, making it easier to seat the bead.

We got a 215/40/18 onto an 18x10 without a cheetah on a wheel with a small drop center. I NEED to use it for my 215/40 on a 17x9.5 with a large drop center.

Anyways, good luck just "inflating the tire" to seat the bead on a stretched tire. It doesn't make it hard to take off either. As long as you get the bead of the tire into the drop center opposite of where the "duckhead" is (where you use the bar).

^ Concurred.

17x9 FN01R-Cs with 215/40 FK452s took ether + lighter to finally bead. Cheetah wasn't working.

17x9.5 Work VS-KF with the same 215/40 FK452s just took a blast of air from the air compressor with a straight fitting on it (no regulating valve that would only allow air to go through when the valve is pushed back) into the valve stem, with the valve component taking out of the valve stem, to bead.

If you look at pics of the VS-KFs, they're like the wheel on the right up there, and the FN is kinda like the wheel on the left.

[awesomenick]

Yep, generally a wheel with a large lip is easier to stretch onto.

Not always the case though.
