I’ve now got 2 punctures in my 14k Old pr3 fear tyre . Have always used sticky string as do all my dispatch mates .

Tyre now needs changing as going around corners has now become interesting , funny even

I thought the later GS's at least the 1100s are actually tubeless and don't require one since the way the spokes are actually fitted. They don't go through the wheels like "normal" pushbike style.
There are other options to add outex? or helicopter tape equivalent to make a spoked wheel tubeless.
May be something for you to look into.
Re 800GS... Like you Riz I thought they were tubeless rims too like the 1200, but they are tube type rims fitted with tubeless tyres and tubes as the spokes go through the centre of the wheel and not through the outer rim as on the 1200. The new 850GS coming out soon does have tubeless rims with spokes which is a much better idea, as it still give you the option of using tubes for serious low pressure off road stuff.

Not sure if I've mentioned this on here before (I have on my other bike's forum) anyway.... July last year the Viffer's rear tyre picked up one of Screwfix's finest :BangHead:

Reluctant to bin a tyre with loads of life left in it i looked for possible fixes and after much research decided on Punturesafe which used to be known as 'Ultraseal' (cost £16 off Ebay. )The main reason i went with Punture-safe was because it claims to be a permanent fix for the life of the tyre unlike the plugs ect. and also there is no speed restriction. (Punture-safe claim 150mph tested)

The other thing i don't like about the 'plug type' of fix is that in order to fit them you've got to first make the hole bigger! turning what was a semi sealing slowish puncture into a rapid deflation situation should the plug ever let go, never mind the additional damage caused to the cords and ply by enlarging the hole.

Because i already had the puncture before installing it, i simply added the required amount through the valve stem, spun the tyre up then inflated it...(Not my idea Puncture-safe claim you can do this ) and up it has remained with no air loss what so ever for hundreds of miles! (200 mile a week commute shared between two bikes)

Riding with it...

At first i was a little paranoid it would let go / go down... but after a couple of weeks of absolutely no air loss my confidence in the product grew and now ride in my usual manner of 70 - 80 and on the odd occasion 90+ :angel

No air loss
No vibration
Won't freeze (tested a sample in the freezer)
Permanent fix.
Washes away with water come tyre change time.

I change my own tyres so wont't be pissing off the tyre fitter... apparently some places charge an extra ten quid if they know its in the tyre!!!! (any old excuse to money grab eh?)

Will i use it again?

Only if i have a puncture... once this tyre is spent i'l be fitting a new one with just air installed :)

My concern is (and why i wouldn't have it in there permanently) is one of corrosion long term? Puncture-safe's site say that this won't happen due to the formula but i;ve read at least one negative review where someone's chrome steel rim apparently corroded, but as you well know there is always a few negative reviews with any product.

When i researched it by typing in 'motorcycle forums puncture safe /ultra seal' rather than finding anything negative i found mainly two types, those who swore by it when touring ect or those which were simply dead against having a liquid in their tyre, no real life experience with it but just apposed to the idea of it. (which i understand as they are pneumatic tyres not hydraulic)

Seeing as i fit my own tyres... i'l post some pictures of the rims condition when i fit a new rear tyre in a couple of months time. Will also post pictures of wheel/tyre pre washed.

P.s. The reason i didn't have a professional fix the tyre was that most if not all garages won't repair a Z rated tyre. I guess they think we all ride around at the tyre's maximum speed limit or would simply prefer to sell you another
Kevin, --- Sorry to hear you had the problem, but glad to hear it all worked out as expected for you ;),
Were you out on the open road when you became aware of it , and how did you go about re-inflating :nusenuse:,
Fortunately I found the tyre to be flat at home. After re-inflating the tyre, the puncture was found to be a small shard of metal but only leaking slowly. I actually went for a short ride but also took a small battery inflator, just in case. On return ~3 Hrs, the tyre had lost around 10 psi, I've ridden on a tyre like this for several thousand miles before. Sometimes its better to leave the offending article in the tyre. As it happens the tyre was worn out anyway so I took the opportunity to try the Stop n Go kit. It was easy to use but glad I practised in the safety of my garage. I then rode the bike at 'normal' speeds to test the repair. The kit is intended as a get you home repair and speeds should not exceed 50mph. I can confirm there were no ill affects at speeds in excess of this however, not that I would recommend riding at excessive speeds of course. I've now replaced the tyre but would have been happy to ride with the repair until the tyre was worn out.

When I've experienced a puncture on the road, as long as it's not flat, I would get to the closest garage with an airline before attempting to repair the tyre. 26678203_10156105838023653_7087410574015336843_o.jpg

Guys, just a warning about Ultraseal / Puncture safe whatever they call it from my experience. I used it religously (leaving it in all the time) hoping it would protect me from flats on long trips abroad. What it did do was rot my rims. Luckily not badly, but it did require cleaning with a drill and a wire mop. I have heard of Pan riders from my local Honda dealership needing to have wheels replaced. The same dealership LLoyds Honda Carlisle did offer sealant with tyre replacement but stopped using it due to the corrosion issues. After a tyre change and SEEING what it had done I decided never to use it again and went down the Stop n' Go route. Then I got a puncture in France, but a 10 minute fix with Stop n' Go and on my way again. Def the best option imho.
If you change your tyre regularly then perhaps with Ultraseal you can keep an eye on it. If you've had it in for longer than a couple of years I suggest you take a wheel off, break the seal and take a look inside. I hope it's ok! The bikes were both VFR, one FiW the other VTEC A6 and it caused corrosion with both...

At the moment I'm thinking about one of these ----

Looking forward to any advice offered by you bunch of knowledgable guys ;),
They are the best kit for a clean puncture. I have ridden over 400 miles on a tyre with 3 of those plugs in it. Not sure what I ran over but it put 3 holes in the tyre. Never lost any air. Just remember to bring a set of short pliers with you to pull the plug tight as its the only thing not in the kit. have fun.

Def buy Stop n’ go kit! Best thing out. I never needed a pair of pliers as pulling on the inserting tool worked for me. Puncture in middle of France, rode without loss of pressure to Carlisle. Binned tyre on return as was worn, but would have fixed with a proper patch. It took only 10mins to fix, took longer to find filling station to blow up to correct pressure so now carry mini compressor as well as gas cartridges. It also fixes lawn mower tyres!
Buy one!!
