Interesting concept, and a way to spend more money!

Chk them tenn. teams!

[MI Dirt Fan]

They had to have tested this before. Because you just don't go sticking that in a tire wondering what it might do. That is though. If it's true.

Not with LM tires but I know a few that would run a tube in a street stock/modified tire usually on the left rear years ago. I know one of them got hit in the left rear during a race with a few laps left and it bent the rim some. If it weren't for the tube he'd of lost the race. He ended up winning.

[OhioRaceFan]

They are using these in go kart tires. Some places have banned them. https://venomjuice.com/?q=node/26

[heinen81]

Exactly, I find the timing of this all to be suspicious. A few weeks ago the kart ArmorWall technology situation/controversy was all over social media in the kart racing world. Then 2 weeks later a Lucas bulletin from an "alleged report", sounds to me like someone just brought up the technology and the rumor spread. Highly doubt it was ever used in a DLM, presently. May not have taken long to eventually get there though.

One of them would gladly trade you $100 for $30k!

Too bad your daddy didn't use one, maybe it would have prevented a leak! :)

I've said this many times......racers themselves and part manufacturers are mostly responsible for costs being where they are today, on both the national and local level.

I’d place way more blame on racers than the part manufacturers. The manufacturers are really only going to produce stuff that will make them money, and new products exist because some racer somewhere asked for it.

[Tireguy17]

I'm sure that is the case on alot of part improvement, but I'm sure just as many evolve from the manufacturer making a part "lighter" or "low drag" or "low friction" or some exotic material and increase the price on the racer.

Should be interesting to see if the results in the coming weeks show who may have been guilty of using this item on their tire(s).

Pretty sure this is a ghost they are chasing.

Pretty sure the 49 team saw something when Bloomquist's tire folded under the car during the B-Main on Friday evening. Lucas officials went down there and found nothing. No big deal, off to the DREAM. Kevin Rumley always trying to get every eye away from the 49 car. Thats why he's the best in the business.

Yea. They saw something.... lol

Somebody else let the cat out of the bag on the tire inserts weeks ago. Lucas has already tore the 49 tires down to look for them.

[No_Weak_Links]

Only part I don't understand is it says like 5x "they can't re-use them"....im sure it would take a little work, but why could they not be reused?

Not sure but i believe it sticks to inside of tire wall. As im told anyways

[MI Dirt Fan]

They are glued to the inner sidewall.

[a25rjr]

It wont be long and dlm will be like nascrap!

Every time someone finds/develops something, its outlawed!

[No_Weak_Links]

They are glued to the inner sidewall.So cut the sidewall out of the tire and a grinder and save $100, or just flip it over and you saved $50 lol

[Illtsate32]

Ehhh, way to many variables, seems like it can have just as many if not more disadvantages, and I dont think there is enough data to prove what they are saying about reducing heat is true. Merely speculation...

Right on they are both to blame they make it lighter, stronger, more expensive cause they know racers will buy it driving the price of racing through the roof.. racing was affordable back in day cause alot of these manufacturers didnt exist and you got your parts from a junkyard or made them yourself, but thats not the world we live in today unfortunately...

[billetbirdcage]

This is a rhetorical question:

So if I make a insert that goes into the tire like a tube and it's not glued to the tire and can be removed and reused, is that legal....................


Hmmm

[Centeroff]

I’m calling BS. Just another rumor on the mill. Reduces flex in the sidewall to reduce heat is what throws me off. I understand the concept but it’s not like these guys run low enough air pressure in the RR to get over on the sidewall anyway. It would throw the balance of the tire off also and if you had a tire come apart there would be no hiding the evidence. Possible but doubtful

[billetbirdcage]

No idea who wrote that or where they got that info about the heat, but part of the idea is to change the side wall flex and therefore the forward drive of the tire.

Back in the day, some LR tires had wedges in the side wall at the bead extending but tapering down into the side wall to stiffen the side wall for more forward from a LR tire.

Changing the tire carcass in anyway will/can effect the tires performance good or bad but it will have an effect, why do you think you can get Hoosier tires in different carcass's right now....

"not like these guys run low enough air pressure in the RR to get over on the sidewall anyway"

Guess you are new, because even at the STD air pressure the RR can roll so far over you can remove all the white paint off the hoosier lettering or that the beadlock is less then an inch from touching the ground at the right high speed/banked/tacky tracks easily, so much so you have to add pressure over the STD.

[Tireguy17]

Its no different that Cup cars wanting to run as low of air pressure as possible. I doubt this device was used on anything but the LR tire to increase traction.

[Josh Bayko]

Hmmm

My guess is that it would be legal until you won some races, then it wouldn't be legal anymore.

[Kromulous]

If you ever drove a SLM you know that used tires lose feel. The tires are big and feel like marshmallows, and when there used, some say more than 3 runs, the side walls get weakened and then lose feel in the car. Along with sharper edges that obviously add more feel.

I could see tire inserts being a big deal, even inner liners for dual air pressures.

[FANSFund]

The first test of the Kevlar inserts was done at Deer Creek. So the "story" of Kevin Rumley noticing something on Bloomquist's wheel at the Show Me and that is when the testing began is absolutely false.

LR tire is what they are checking.

The above posts about the tire would be LR, stiffening the sidewall, inserts allow lower tire pressures to be run and lower heat in tire are spot-on and shows the knowledge and understanding of those posts.

If your interested in what is going on... discuss with Rick Schwallie, Steve Francis or one of the crew members of the Lucas teams... they all know what is going on, what the insert is for and why the advantage.

It's not just absolutely false. It's absolutely impossible

[Tireguy17]

What's impossible?

[MI Dirt Fan]

To "notice" something on the inside of a tire...

[Kromulous]

While true, from the outside, you would probably notice that the tire had really low pressure. One side wall may be more wrinkled up, low pressure, than the other. There could a different rim being used. A lot of possibilities.

One thing i noticed over the year about guys that are great at their craft is no detail is to small, down to wind drag on hood clips... seriously. So could he (Rumley) noticed that a tire looked odd? sure.

Obviously you're not risking $30,000 by trying something new. The report was a Lucas driver was using the tire inserts on the left front and left rear. It was 100% false as Lucas looked over the cars before the feature and after.

[Planetzer0]

To "notice" something on the inside of a tire...Not when the tire rolls under the car with every camera focused in on it.

[MI Dirt Fan]

That's how your able to see inside the tire when it's mounted on a rim?

[Centeroff]

billittbirdcage, I haven’t seen Hoosier rubbed off the RR in years and especially the bead being 1” from the track surface. Maybe on a rough surface but then again I haven’t been to a big track since Syracuse in the late 1990s. Speeds were so fast up there we had to run 1” washers and bolts on the roof because the rivits were tearing through the metal of the roof. It locked down on the bottom and was a terrible race to run 16th. We ran Hoosier 70s that day and a bunch of air and still had 3 flats. Figured out later we didn’t have enough air and was on the sidewall. Maybe we needed some Kevlar lol

Tmac doesn't run them

[SLIDING SIDEWAYS]

May b you should have gotten some advice from brett hearn or gary ballough on your syracuse issue!

[Josh Bayko]

Syracuse was an animal that no other track can really relate to.

[Centeroff]

Josh you said that right

[Josh Bayko]

Josh you said that right

How much different Syracuse cars were compared to the cars at weekly tracks and the SDS was pretty eye opening. It went way deeper than a new body and a quick fill.

Yea they didnt call it the "moody mile" for nothing

[Bubstr]

To understand this, you need to learn about tire slip angles. Learn that and let your mind wander with it.

If there is a tire rule, this could circumvent it's purpose. The good tech guy says illegal.

[kdawg]

Funny how go carts used "kevlar" for years, not as a insert though

[CageFaraday]

This is why I'm for, "Open Compound/Open Supplier" tire rules, it helps negate the temptation to cheat so much if you can just buy the tire you need, same costs as any other. When the box gets too tight, the costs invariably go up as everyone scrambles in search of the smallest performance gain. These guys are the "Top" of the sport, "Professionals" let them run open compound and be done with it. JMO, your mileage may vary.
