Plug (pasak) then Patch (tapal) on tire?

**k_leos** · December 28th, 2021 10:08 PM

Hi, this morning, na flat ako and I went to a car service center and saw they put plug/pasak (like spaghetti) on the hole. Pero pinalaki muna nila hole to insert it. Yet the technician couldn't insert it. Kaya linagay kunti oil to let it slip. Naka rinig ka ng ganya? But nowhere did I read in the net that it was ok to put some oil. I'm afraid it may either slip or the air inside may get into the belt/ply. What would happen if pa patch ko yun portion inside it to seal the belt/play on the plug/pasak spot?

I have a plug/pasak DIY puncture repair kit which I bring in my road trips. Used it twice, yup, its very difficult to insert esp if your tire thread is still thick. My kit has a tube of repair glue included, you put the glue into the puncture before you insert the plug. The oil you think they used is probably the repair kit glue.

I always have it redone in proper vulca shops using the patch. In my observation no air is lost using the plug, I have a tpms to monitor it.

I'm sure they used oil because the main technician said the assistant get some oil to make easy to insert and I saw him with an old can with oil from the engine oil replacement area and got screwdriver to let the oil in. They didn't use the repair kit glue. The assistant said it was alll oil and rubberized strings. But I'm beginning to worry because I read the hole should be rough and not smoothing it with oil. Also I read plug/pasak can damage the steel belt that keeps the tire's structure intact and can cause bulge in the spot.

If I'd have patch done tomorrow on the spot by opening up the rim. What would likely happen since the hole is now bigger than the original? Would it cause other side effect. A new tire costs 11,000 pesos.

About patch. Does anyone know a service center (or vulcanizing shop) around the Thomas Morato Ave area (Timog St) in QC that uses so called cold patch system inside rim instead of using high temperature? How many still use the latter? Also service center with good security because you don't want to be vulnerable with a car inside a corner.

You can dm me if it is not allowed to post a shop name.

I assume it is safe to patch a tire that was already plugged (pasak). Thanks.

The vulca shop crew will use a plier to take off the plug, grind the surface, put a glue and the patch.
The plug is not a piece of metal its ruberry but softer it will contract. So it will not be any bigger than the original hole.

I had a puncture before that needed 2 patches to cover the hole. The patch outlived the life of the tire thread.

I mean originally, only a nail was in the tire. Then they used screwdriver to make the hole bigger so the rubber plug could fit (as many who users who saw the procedure reported).

If the new shop will put patches inside. He still has to remove the rubber plug? I thought it would remain. What happens if it would not be removed? Without any thing to block the rubber outside, won't air/water from outside like flood, can slowly seep into the belt/ply system over the years?

When you insert the plug, there will be an extension of the plug protruding inside the tire. Since its soft rubber, grinding it will be difficult, thats why the crew will remove it using a long nose plier. In most instances all the plug will come out, some will be left behind.

I prefer to leave some part of the plug behind to cover whatever the patch plus tire pressure could not cover.

A puncture is a puncture, its a hole, removing the nail that caused the puncture will not heal the tire, there will still be a hole in there. Patches and plug do their job to keep the air inside your tire. Unless your tire is made of biodegradable rubber, you should not worry about air and water creeping in a tiny hole.

This is a surprisingly long discussion for a very simple topic.

I get my vulcanizing done at Goodyear Servitek near my place. 400 pesos with a decent tire changer and good mechanics. They use your typical patches.

Have tracked my car several times with patched tires, also countless roadtrips.

If you don’t feel confident with the repair of the tire, change it. Simple as that.

My questions.

1. Ano torques used in the impact wrench? Is it hydraulic? Kasi if ma overtighten ang nuts ay mabasag nuts (masira rin yun bolts)?

2. Very necessary ang car stand? Kasi I haven't used the car since Dec 28. Bukas balak ko palit reserba na tire before going to the service center pero ordinary screw car jack lang gamit ko. Hindi pa ako naka palit tire so I wonder if ma slip yun screw car jack and absolutely necessary to buy a car stand and put under the suspensions.

My last questions po. Hehe. Sori for the questions but I have been googling it yesterday and couldn't find the answers especially the torques of the impact wrench used and what wattage (based on the video).
