Currently im running
Front 19x9.5 w/ 225/40r19
Rear 19x10.5 w/ 245/40r19

How hard do u guys drive your cars? Meaning do u guys take turns at like 60 plus mph and so on
Thnx for the input.




Also did u guys have a problem with the beads sitting. My tires have a small leak coming from in between the bead and rim. Already put bead sealant on and to no avail. Any help with that issue. This is my first time running stretched tires

Did you take the same turn @ 60MPH before the stretch? IF so then you should be able to do it after...

The contact patch doesn't change from stretch, sidewall will get a bit stiffer though.

What tires are u running? Some tires are better for stretching. Yokohama s drives are some of the best. Yes I have driven the car hard with no issues. See sig for stats.

You sure it's because of the stretch? No hole or nail stuck on your tire?

I'm running 235 on 9.5s and i drive hard plus drift my car every week. Never had problems so far. I usually run 30 to 32 psi.

totally useless















Stretch stiffens the sidewall and increases feedback, steering and throttle inputs. obviously if your putting a 215 on a 10" your not going to be auto-xing but stretch is very useful within range. 245 on a 10" is really not that big of a deal.

I'm trying to get clarification on this issue.

If what you want is absolute performance and you don't care about looks at all (well actually you dislike stretched but are willing to sacrifice for performance) should you have any stretch at all?

The OEM's don't do it that's for sure.

^Depends on the purpose
Function isn't function isn't function.

What KIND of performance do you want?

Every driver is different, there is not one ultimate way to set up a car. even in a race as specific as drag racing. they set up the car around the driver, not the other way around.

Best way to improve your cars performance = High Performance Driving School/Event

if your looking for all out performance you start out with yourself, begin to understand your driving style and what modifications could be made to accentuate it. I.E. if you use more front end grip or the throttle to steer through a turn, then you experiment with one part at a time adjusting the settings till you have time lap evidence that it actually makes you faster.

The thing is that I do not have the funds or the time to develop my ideal set up. Which is fine because it really isn't necessary as the tech work has been done to a large extent. At least good enough for me to improve my enjoyment in the canyons and get the most out of my set up.

I've done a bit of reading on this subject at motoiq.com (loads painfully slow btw) and my understanding is this: A very small amount of stretch is indeed beneficial for both handling feel and absolute traction. In short, the tire manufacturers have a range of rim sizes that they recommend for each tire. Pick a tire size to match your current rim that is either in the middle range of your particular rim rize or just one size smaller while still remaining within the tire manufacturers recommendations for rim size. Get it?

Also, the 'muffin poppin' look is quite bad for handling. This might explain why my buddies S2000 that is all set up w/ trick parts is an absolute handful on canyon roads w/ his 'muffin poppin' tires.

^I've heard the opposite runs true (for road courses anyways), you want a little bit of tire flex to improve predictibility.
Stretched (stiff) sidewalls will go the the breaking point, then immediately let go.
A softer (less stretched) sidewall will reach it's limit, then as it lets go, will still maintain more traction that the stiff sidewall, and will recover faster/easier.

The stiff sidewall is preferred for drifting because you want it to let go when asked, canyons I would assume are closer to a road course though..

But this isn't from personal experience and I'm not an expert, just what I've read mostly.

Stretched tires are for the most part only useful for drifting, and stretch and poke.

The reason being is pretty simple, stretching the tire puts the sidewall in tension and doesn't allow for sidewall flex. This makes the breakaway point smooth and predictable, as well as reduces tank slapping because the tires don't just suddenly grab.

Flexible sidewalls, do allow for more mechanical grip because it allows the tire to flex over bumps and road imperfections, maintaining the contact patch.
