    Default Corroded wheels warning

    Whilst I was in Watling tyres yesterday picking up my new tyres I caught side of some photos of a badly eaten away alloy wheel. I asked the chap about it and he explained the wheels were off a 2009 Fazer and they were like new on the outside but totally eaten away on the inside. He had to use copious amounts of bead sealant and it took him an hour to get the new tyres to seal. It is the punture deterent or sealer that does the damage. Slime Ultraseal are all the same. Apparently Ultraseal is the worst as it has Phenol in it. So if you have this in your tyres for long periods it is likely to eat your wheels. I am aware that Phenol is corrosive to metals and having seen the damage to the wheels I am convinced that there be some truth in what Watling tell me.

    If the damage can be proved, there are going to be a few court cases for new wheels.

    Meh, some of Guzzi's 'tubeless' rims are notoriously porous. So much so that using a tube is a good idea, unless you like the idea of pumping your tyres up every day.

    Corroded hidden area of alloy wheel?

    First suspect: ingress of water or salty water.

    Next suspect: Fairy Liquid used as tyre fitting lubricant. Really the same as a small amount of salty water.

    "Phenol" has some corrosive effects on aluminium, but is it in Slime as an aqueous solution of carbolic acid?

    If the phenol group (is that the right word?) is part of a bigger organic compound, then it may have no corrosive effect at all. Bakelite knobs on wirelesses don't corrode their spindles. Phenolic manifold spacers don't corrode carburettors.

    I know nothing about this shit, but then how much does Watlings' tyre fitter know?

    There were some pictures of badly corroded wheels on the CR250 website. The blame was attached to the use of duct tape instead of proper rim tape.

    Yeah, or the fact people ride around on surfaces covered in a corrosive powder 3-4 months of the year.

    Deffo one of the two

    On my last bike, I used some stuff called "ride-on tps" selant. At the time there seemed to be a lot of rumours about fake ultraseal, and it also seemed quite expensive so I was looking for alternatives. This ride-on stuff was just starting to be sold in the UK and a lot of the americans seemed to swear by it.

    From what I remember of their marketing blurb I think they mentioned that it was different from ultraseal and slime in that it wouldn't rot aluminium rims? Might be worth a look if anyone is looking for an alternative (check the details of course in case I'm wrong but I seem to remember that being one of their selling points).

    My new bike I recently discovered has some corrosion inside the rim when having new tyres fitted, and they look perfect from the outside. Haven't used any sealant in these though and it must have been like that when I bought it. I'm guessing age and water has had more to do with it (or judging by the patched tube - perhaps a roadside repair that's left some moisture trapped in the rim at some point or something along those lines).

    The screw-on cap on the valve? The bloke's a loony. Those same Schrader caps have been used since, literally, the dawn of motor transport!

    Did he reckon it was ok to use the metal nut, further down the valve? And what about the black plastic caps with the sneaky metal threaded lining?

    I suspect the tyre monkey was referring to cheap anodised aluminium shite rather than stainless steel or brass.

    Sticky tape with a woven print on it will do.
