Got a 2003 base with a Brembo upgrade and read here that the spare will not work.
Was looking a mag. And saw an advertisement on Tyreguard

I tried to search here and nothing on it.
Does anyone have used it?
Some input?
I barely use my Z now and some weigh reduction is always welcome.

 

Personally, I wouldn't touch it. It appears to be a coating applied to the inner surface of the tire that supposedly provides a automatic seal in case of puncture. Unless it stays in a liquid form, I fail to see how it's going to ooze into a puncture to seal it, otherwise the puncture goes through it too, right? If it stays in a liquid form, it would run and settle to the bottom of the tire when parked for a extended length of time. Seems like it would be impossible to balance a wheel and keep it that way.

Then there's the issue of high speed rating - a puncture could damage one or more of the steel belts. That automatically lowers the speed rating of your tire. If this stuff seals a puncture, then you never know that the tire has been compromised.

What happens when you have a large puncture, cut, blowout? You're still gonna need a spare.

From a Google search, I don't see what looks like a lot of experience using it, just a bunch of sales/marketing related BS. I'd wait a year or two until all the problems with it are known for certain.

 

I think that once injected into the tire and driven around, the formula coats the inner side of the tire and settles. It then probably becomes a gel-like substance which stays on the tire. In case of a puncture, the gel will fully surround the intruding object. Even if the foreign object was removed, the gel will probably have enough elasticity and adhesion properties to seal the puncture. Of course, for safety, these won't be some super substance which can take any puncture or impact. It probably has its limitations well within boundaries of safety.

At least that's what I think that is anyway. There are other products like this (preventative measure).

 

Correct, but that gel has to have certain elastic properties that allow it to flow. How thick does it have to go on??? Too thick and you're adding weight to the tire. Too thin and it limits the ability to seal anything but a needle sized hole. Too stiff and it won't flow, too elastic and it flows when and where you don't want it. What does it cost? What expertise does it take to apply?

OP would be better off buying runflats until this stuff has proven itself.

BTW - you definitely don't want to try it on a TPMS equipped car. They claim it's compatible, but TPMS manufactures recommend against using any kind of tire sealants.

 

I'm wondering about the initial premise, the spare won't work with the Brembos. I have an '06 GT with the Brembos. I also happen to have an '03 spare that I got with a second set of used wheels that I bought, and as near as I can tell, my stock spare is exactly the same the spare from the '03.

 

Brembo equipped Zs have a 17" spare, the others use a 16" spare. That was the first thing I had to replace when upgrading to Brembos. IIRC, the 16" spare will fit as the rear wheel but not as a front.

 

"Glue in a can" is as old as jesus. Bad idea.

 

If it fits the rear, then I have no issue ( I’ll try it on the week end). The only problem would be to change 2 tires if one of the fronts is flat. I read one thread here that said it would not fit the rear either that was why I was looking for alternative.

I have been on the Brembos for a couple of years but have not got a flat on that time.(Toyo T1R – have been great).

Many new high end vehicles are coming without spare. Those either got some king of glue and compressor or a puncture kit to save weight or due to lack of space.

Thanks for the inputs!

 

Or they use run-flats

 

We have a good system made by Continental called the ContiComfortKit. Contains a latex liquid that is not harmful or will ball up once driven like other inflation kit propellants. Comes oe on the Ford GT supercar.

 

used a gel similar to the tyreguardian long ago - dont remember the brand
rusted the wheel where it came into contact with and was a complete mess when changing tire from the wheel.
not sure if this will have the same result.

 

These liquid flat-fix products are not recommended for low profile tires. I found out the hard way......it throws them out of balance.

After using slime, at speed, I got the steering wheel shimmy.

 

Buy the properly-sized spare, get RFTs, get the Coni liquid from TTR, or risk it. You weight the risk/reward for each.
