Puncture today

[MrGrumpy]

Car or bike, garages always come out with cant be repaired you need a new tyre. Now I know I am going to get jumped on but once again I am going to plug 'Puncture safe', 'Ultra Seal'. The night before my camping trip last month I noticed something in the rear tyre. The pressure was fine, but I decided to pull the thing out. It must have been in for a while because it turned out to be a large screw with the head missing. I had Puncture Safe in the tyre and it had made a tight seal around the screw. However with a screw PS recommend that you unscrew it rather than pull it out. This way Puncture Safe seals the hole on the way out, I did not do this so Puncture safe could not maintain a seal over 22 psi. So I also had to resort to one of those worm type plugs, that coupled with the PS seems to have made a good secure seal. Its been a month, I have been away loaded with camping gear, off road and sat between 70 and 80 mph on the motorway. No problems and no loss of pressure. My choice I know but I shall not be replacing my tyre until its worn out.

So this doesn't sound like an especially good ad for Puncture Seal! It didn't work as you had to resort to the plug! The temp plugs do work well, usually far better than their promised limitations imply.
As I've said before the gunges have failed me before, and if they do fail, you are screwed utterly.

"its been a few years so I might be wrong but on datas bike a 3mm plug is or was the largest allowed by law and 6mm on tyres rated 60 mph or less"

Now you mention it, I think you may be right - we only do car tyres but I can also remember reading something along the lines of high speed motorcycle tyres losing their speed rating when repaired. I'll have to look into that.

If you read the instructions they say you can pull out nails but that you should unscrew a screw. This is because the thread can do even more damage when it is pulled out. There had been no leakage at all until I pulled it out. It then resealed and was good for 22 psi. However once I went over that it started a slow leak, which is what the instructions say will happen. The plug and the sealant seem to be doing an excellent job. I check my tyres before a long run and they have not needed topping up, I also have pressure monitor caps fitted and they have remained a healthy green colour.

This is an interesting read regarding tyre repairs. Might not be what some want to hear - especially Dunlop's speed recommendations for a correctly repaired tyre!

Continental are now selling tyres with something similar to ultra seal already in them. With many car manufacturers now not providing spare tyres this is seen as a way forward.

[Steve_D]

"ContiSeal tyres contain a pre-applied, sticky, viscous layer that covers the inside of the tread from shoulder to shoulder".

"Can you repair a ContiSealTM tyre after a puncture?
Yes, assuming the tyre is in a repairable state you can get the tyre repaired. As with any tyre, you should take it to a trained tyre specialist to assess if it can be repaired or not".

In other words, yes in theory but who is going to spend time scraping off that sticky, viscous layer and guarantee the adhesion of a mushroom patch? I'll tell ya - no one!

Just stick a tube in it.
Used to be done regular in days gone by.

OK mostly sensible, but the idea that notion that cleaning out ultraseal or similar when a tyre is being replaced or repaired is a difficult or time consuming job is nonsense. It takes 30 secs with a tap and a wet rag! If it upsets your trained tyre technician then he must be a lazy git!

No Grumpy, it worked! It just didn't make a permanent repair on this occasion. However, it sealed the puncture around the nail allowing me to ride over 120 miles in total with no measureable loss of pressure. Without PunctureSafe the tyre would have deflated for sure and I may have possibly come off as the puncture would have been a slow one and it's the slow ones that are most dangerous. I know from experience, nearly killed 30 years ago by a slow rear puncture on a motorcycle. Cruising in a straight line on the dual carriageway for miles and then went to corner and the whole back of the bike just slide from under me. No prior symptoms of the puncture in a straight line were noticeable but the tyre let go on the bend. I was doing 60mph. Used Ultraseal (now PunctureSafe of course) since then. It's the only one to use and better than any of the others as it makes a permanent repair with no speed restrictions, well it's now certified to 173mph or something like that. Up from 156mph which is used to be.

Oh! Well! Now its certified to 173 rather than 156 that makes all the difference!!!
