New Tyre Blue Sealant.

[MissBex]

Hya, just had a new rear tyre fitted (tubeless) and I noticed some blue liquid (sealant?) a little on the tyre after a running in ride today.

Is that normal?

[MaybeGuy]

maybe they damaged your rim, and bodged it with hylomar. They should use lubricant to get it on, nothing to seal it.

heya, thanks for the reply. Is there anyway to tell if they have? I might just pay them a visit to ask.

[P.]

This is why you should try to DIY.

Im guessing the bikes chinese tbh, because your tyre came off last time.. now its leaking

[MissBex]

its the one in the picture. Honda CB500S. (workhorse xD)

[MissBex]

today I had another ride on it, seems to be ok as far as the blue stuff is concerned, it could be just a bit left over from the old tyre has rubbed off onto it.

I wanted to check both of my tyres pressures so I went and brought a tyre pressure guage.

I'm a little concerned about the readings though. The front said 17 and the rear (new one) said 25. Checked again an hour later when the tyres were fulled cooled and i got the readings 16.5 and 19..

The tyres are bridgestone battleaxe bt-45's and it saids 41 on them which is the max pressure, when i looked online and even emailed bridgestone, they said the correct pressures should be:
36 front, 41 rear.

Feeling the tyres, they both feel really solid and I cant see double the amount of air being put into them..

I'm going to need to checky my guage against another one i think, Surely it cant be right.

hi ya, i dont know if its any different to a car but im a Car tire fitter and if the rim is corroded where the bead sits we wire brush the corrosion off and bead seal it up, its like liquid rubber solution stops corroding of your rim,


hope this helps

Pressures will drop as the tyre and rim cool after a ride, this is normal.

Your pressures are far too low, don't go by the "poke it and see" method; Use an accurate gauge and set it to the manufacturer specified pressure. The bike will handle much better for it, and you won't ruin your tyres.

Running them that low will make them wear unevenly, and maybe overheat the tyre too.

If it is quite a light blue, then it is the stuff they use to slip the tyre on easier. They use paint brushes in the paste around the edge of the tyre to get it on. Never clean it off

Thats at the place I go anyway

Thanks for the info peeps.

The guage must be faulty. I'm gonna get a new one tommorrow and check them again. Then I can pump them up to 36f and 41r if needed.

The Honda manual says for pirelli and dunlop tyres 29f and 33r for driver only, but as im using Bridgestone BT-45's, Bridgestone emailed me and recommended to have them at 36 and 41.

I'll update with the new guage's readings

[chris-red]

Can you wash it off with a sponge and water? It is likely just the lube they used to get the tyre on.

Heya, yea I wiped it off. It's probably what you say.

I got a new guage and tested it on my bike, I'm still getting silly readings like 10 psi front and 17 rear.

I decided to check it out on my friends car tyres and it gave the correct readings :/ It's really odd.

[cb1rocket]

if the gauge is fine then whack way more air in!

Go to one of the petrol station/garages that have the digital airlines. It cut outs when you get to the correct pressure that you set

[MissBex]

Been to the garage and filled them up, Checked the guage again and its saying 8psi for the front.

[.....]

What pressure gauge are you using?

Without meaning to sound patronising, are you sure you're using it right and seating it properly on the valve?

[MissBex]

The first one was a gp moto one and this new one is an oxford one. I'm sure I'm doing it right, even my friend tried himself and he got the same low readings.

[P.]

Even though its frowned upon, ride to a garage and pay the 20p, see what the machine says... leave the bike to cool the tyres down if you need.

If you have a leak, you'll hear it. I heard such a tiny hole on my rear tyre a while ago.. small was an understatement

[Noxious89123]

FYI, if the pressures are that low, a garage compressor might not work. (Some have a function for inflating nearly flat tyres). Also, they tend to be rather inacurate.

Foot pump and a decent gauge is the best way to go. I would also ignore the email from bridgestone and go with the manufacturer pressures, unless they specified those pressures are *speficically for your bike* and not just the generic recommended max pressure for those tyres.

I've ridden a CB500 with the pressures down to about 18psi in each tyre, and I thought I was going to die. Wobbly, won't lean into a corner then flops right over. Horrible experience.

If your pressures are that low then I'm surprised you can ride it. I wouldn't ride it in that state, there's a risk of the bead breaking (particularly on new tyres) leaving you with a tyre not fixed to the rim, and with no air at all in it.

Assuming the pressure is that low, and you're not just incapable of using a guage, then go back to the place that fitted the tyres. It will be either a puncture, a knackered valve, or the bead not sealing.

As a general rule, tyres may lose a very small amount of pressure over a long period of time, 2-3 PSI over a month would be my tolerance. More than that and something is definitely leaking, which can lead to the tyre suddenly losing all pressure and hurting you.

A tyre like that will always feel solid. Tyres are made up of very stiff rubber supported on metal wires. You wouldn't be able to squeeze one enough to feel a change if it was totally flat.

[cb1rocket]

is the tyre valve faulty? We haven't heard much lately, keep us updated

[MissBex]

Heya all again.

Well turns out that they really must have been flat. When I used the air from an old machine at a garage next to my house it said it filled up, but as you know I was still getting the low readings, so It cant have worked properly. Been thinking that something is definatly not right, either with what I'm doing, like you say, or with the tyres or guages.

Today I took it to a Tesco garage and because it's a newer machine it actually showed me what pressure was in the tyre, unlike the old one i used previously. Indeed it actually said 10 psi xD

Pumped the front and the back up, tested my guage and the guage messured it 2 psi under from what the tesco machine read, so im pleased now and I shall endevour to keep them topped up regulary from now on.

The ride feels alot better

Thanks all for your help and info

[MaybeGuy]

the fact you have to 'top it up' anyway would indicate a fucked tyre/wheel, hence the need for sealant.

Go back and ask them WTF
