Tyre Goop & Slow Leaks

Hello Tiger,

When I was a service manager at a JD dealer back then, we used a lot of multi-seal on new lawn equipment tires because the customers did not want to be bothered with random flat tires.

In this area we have a lot of mesquite thorns and sand briars that will puncture tires from the time they are new.

Fix a Flat in a can is useless, but Walmart sells plenty of it. LOL

Have to keep a heads up when trying to find and buy a good inner tube now days.


Lots of china junk that split easily and not cheap in price.

I've had good luck with Carlisle/Carstar, firestone.

TireJect is the only sealant that works on sidewall cracks and continues to work over time. Haven't had one come back yet. It even advertises this on the label. It is water based and cleans out very easy. For a bead leak, I break the bead connection, clean both surfaces and apply bead sealant.

I've found that it's usually a combination of old tires and bead leaks, particularly if the tire has been low, and debris and water were able to penetrate into the bead area. I remove the tire, completely clean off the rim with a wire brush in the grinder, then paint it. I use good metal valve stems. When I replace the tire, I normally buy 4-ply lug tires, just to get them off the ground that extra space of the solid lugs from the things on the ground [thorns, etc.] that make tiny holes in the normal turf tires with slow leaks. My last pair of 16x6.50-8 tires were about $52 incl shipping via Walmart Online, and worth it to replace once and for all tires that would no longer hold air, and were always flat when I went to use the trailer. I've tried various "Slime" products and inner tubes, and both are a pain and always seems to cause more problems in the long run. Be aware that small tires are a pain to unmount and mount, particularly new stiff ones. I use a Harbor Freight mini tire changer for some of the changing jobs, with lots of lube made of coolant and dish soap. A couple cheap tire irons from Harbor Freight are definitely worth it. Plus the lug tires on this little mower utility trailer just make it look good... like it fits in with all the big-boy equipment.

Slow leaks are when the tyre loses pressure over many days.

Mower tyres seem to be particularly prone to slow leaks. Small volume and lightweight construction, likly causes.

I am attracted to the idea of using one of the liquid "goop" repairs, to extend the time between needing to add air to my tyres.

• Is this a good idea?
• If so, what goop do you recomend?
• If not, please explain?

Note: I check my Schrader valves and replace if they are leaking - very rarely the problem.

Avoid the goop....just not worth the aftermath.....
