I was just about to order a repair kit for tubeless tyres, when I noticed an ad for ULTRASEAL.

Anyone used this gunk? Any comments or suggestions re: whether this stuff really does live up to its reviews or alternative buys would be appreciated.

Cheers.

Hi, I have worked as a motorcycle mechanic for 30 years and fixed a lot of flats. If ultraseal is a good product.... great. But don't trust only one way to repair. If I have a bad flat with tubless and don't have a strong air compressor I need a tube to get the tire seated on the rim and inflated. I have used stuff in the tire and carried a tube and patches and a tubless tire plug kit.

Hi

I just put Ultraseal in the tubes of my Africa Twin before I left for my trip a month ago.

It was easy to apply and thus far (4 weeks 2500 miles mainly tarmac)no punctures yet(touch wood) - No idea whether this is due to luck/ my riding/ or the ultraseal!

However as suggestedby Bill I also carry a puncture repair kit and compressor as back-up.

Doesn't seem to affect handling.

Cheers

Thanks for your advice so far guys. Bought Ultraseal at a discount today, so time will tell!

Happy and safe travels.

Ultraseal does work, i know a few people who have used this but it is a temporary repair. You should "try" and get it professionaly repaired asap. One downside is that most tyre fitters wont touch the tyre after its been ultrasealed, so in many cases, if you use it , you bin the tyre. I think its best left for emergencies.

I always run Slime in my tyres - magic stuff. Put it in a new tyre and forget about puctures. Picked up loads of nails etc going through India but the Slime always sealed the holes. Only had to fix 1 pucture in 40,000 miles from UK-NZ and that was a 1cm square hole that I couldn't fix with a tubeless puncture repair kit either.

I've used Ultraseal with Bridgestone H/D tubes and Mich Deserts (and now a front Metz Sahara) for 20000 kms in Africa. No punctures! Maybe you should carry a spare set of tubes. I don't.

My friend is a Vendor for Puncture Seal or is it Ultraseal, anyway, most of our group have had the tyres 'sealed'. One of the guys who didn't got a nail and caused him to miss half of the ride out.
2 riders reported having punctures that sealed leaving a pink 'thumbprint' but did not know about the punctures at the time.
That one unlucky rider was me - I wrecked my Pan European causing nearly £4000 in repair bills and a broken leg!
Bike is due out of Sherwoods of Birmingham today - think I'll invest in some now.

Hi
Ultraseal is a pre puncture sealant and tyre conditioner - it is the only product of its type to pass US & UK Military tests, also the US govt Fed Mail etc, etc, etc. It is a permanent sealent and as others have mentioned it will leave a colour 'track' or thumb print - I have used this and it does work. I was so impressed that I have taken out an agency agt with Ultraseal - so if you want it let me know: I can post for self fitment or if you are in the South East I can seal the tyres for you.

Regards

I used Slime in my AT tyres and found it effective. Then I read an article by a bike tyre fitting company which was totally opposed and said that ALL technical advice was against it. They said it also increased weight exactly where you dont want it.

So I dont know - it's all very confusing....

Good roads

Some extra weight in the tires can't be so bad, right? We're not talking about kilos. Certainly nothing like tire treads loaded with mud or clay. I use a similar product in my bicycle in Colorado (after a flat caused by a tiny nail). I haven't had another flat in years. If I ran tubeless tires on my motorcycle, I'd be all about the Ultraseal type products.

The point about weight is that it is unsprung weight right on the circumference of a tyre/wheel, greatly magnifying its effect. That's what the experts say anyway.

Someone else quoted military approval - well bikes are hardly military spec. This approval is of no use to a biker. Most military vehicles are large, clumsy, very heavy, and operate at low speeds with ultra thick tyres.

The experts may stone me (wouldn't be the first time I've been stoned), but a few ounces of Ultraseal can't be so bad can it? My bike is loaded down with gear (none of it is BMW authorized equipment- I deserve another stoning!). Go with your gut, just seems like a no-brainer to me.

One of my bikes is military spec although I've got no idea whether there is any ultraseal in its tyres yet, so it's approval must be of some use.
Being a Harley of course it's also large, clumsy, very heavy and operates at .........
....... Yeah OK - you might well have a point
