Tyre sealant

[Jewellbags]

I carry a spare anyway but what are your thoughts on tyre sealants (slime) ?

 

[Phill D]

Had it my tyres for past several years, does it work well I don't know. As you won't know if you get a basic puncture.

I used some in a cycle tyres a couple of years ago and got a lot of flats with the gunge bunging up the valve cores. Had to replace the inner tubes to stop it happening - lesson learnt

If valve cores were clogging then it is likely they were leaky. Or the dose qty was incorrect.
The cores are removed to insert the goo then the valve thread wiped and core inserted, anything else will result in clogged valves.

I've been running my mountain bike completely tubeless for several years. Tubeless totally relies on sealant liquid sloshing around inside. My wheels get a lot of abuse. Pulled thorns out without issue, just a wet rasp for a second before it seals. Multi-hour rides across the passes in the Peaks and Wales. Red runs at the bike park. Never had a puncture.

Because you don’t get a puncture you don’t get notice that anything’s in there, so you could have a screw or nail or something in there a long time doing damage that eventually destroys the tyre.
I used to use it on a caravan we had but it can cause imbalance if the tyre has internal mouldings that trap it and stops it evening out.

It's normally the "running on it when it's flat" bit that does the damage.

It should not be used in tyres that have internal mouldings like run flats. It causes poor distribution and possible imbalance.
Used in normal tyres, applied correctly, and in the correct qty it is effective with normal punctures

One consideration is how much is pisses off the tyre fitter when the tyre does need changing...

And if you leave the vehicle still for long periods, it will congeal into a lump that puts the wheel out of balance and stops providing protection.

My experience over 12 years in our motorhome is neither of these points are a problem.

It's like all of these type of things, it's about personal choice and personal confidence in the product.
It's not for everyone.

I spoke to the Kwikfit mobile guy who services our hire fleet and he says it is good.

Thanks all for the comments

Had it installed and on the way home via M4 every uneven bump sent the steering into a bit of a wobble like an unbalanced wheel.

Contacted the fitting company and was advised may need balancing. Went to local tyre garage who put the front tyres on the balancing machine and advised they would not be able to balance the wheels as every time they stopped the machine to fit weights the balance weight position changed. Also they had got to nearly a foot of weights to be stuck in one of the wheels to achieve something near.

So all 4 wheels & tyres removed, washed out, refitted and balanced. All as it should be.

Have to say the fitting company refunded the cost of installation and removal.

Photos available if your not going too or have eaten recently. Speaking of which the photos show the sealant had not covered all areas of the tyre and therefore could be considered ineffective.

Again, back to cycles. They used to use goopy slime and didn't work particularly well. The modern stuff is a thin liquid that continuously washes around inside the wheel. The liquid contains fine sand-like particles that work with the fluid to congeal when it finds a hole.

Sadly, looking at the photos when they removed the gunk from mine the covered was very patchy. Not what was expected.

Strangely my lawn tractor/mower used to get punctures all the time (hawthorn hedges) so put green snot in them.... Still got punctures.
Put inner tubes in and haven't had a puncture since.

Yeah Mike Wood in Devizes said similar. OK in low speed stuff like lawn mowers / tractors but no go in anything much quicker, His tyre fitter were not happy washing out the sealant.
