Can anyone lend me tyre warmers for 7 April?

[SILVER SUZI]

Hi guys/girls.
Does anyone have a set of tire warmers they would be willing to lend me for the 5th and final round of the AMCC club racing on April 7th.
Mine decided to try and melt a hole in my rear tire at the last round, and it looks like the front is about to do the same. Can't afford to buy new ones at the moment.
I'm only racing in clubmans, so if I can't get some it's not the end of the world as there are no points at stake. But I would still prefer to go out on warm tires over cold.
I'm in Jafa land so probably makes sense if it's someone up (or down depending where you live) here who can loan me a set. Obviously i'll come pick em up, and drop em back again.
Cheers in advance to anyone who can help.

do burnouts.

Check the input voltage to the tyre warmers, as this is probably why they are burning out, before burning out someone elses.

Could well be worth checking when I'm at the track next, as we all assume we are receiving 240V or thereabouts, but I guess with everyone running tire warmers, starters and the like it could be putting excessive drain on the system.
By "input voltage" are you referring to the voltage being supplied to the warmers? Or would I need to be measuring amperage?
I'm no electrician so this could get beyond me pretty quickly. What kind of voltage would cause tire warmers to burn out, low, high or either?

When the voltage drops the amperage automatically goes up (volts x amps = watts) which tests the capacity of the cable. Any weakspot will light up like a toaster element!

Er, no..

P = V^2/R (Power = voltage squared/resistance.)

power (heat output) decreases as voltage decreases.


If the supply voltage was the cause, every computer in NZ would've fried before your tyres overheated.

They're basically an electric blanket that goes around wheels, there's very little chance they'll fail in such a way that a hotspot will be created..

It will be a faulty thermostat letting tyre temp rise too high.

there not black plain tyre warmers (motao?) ones
i had a set that did the exact same thing. couple other people i know had same issue too

No not black Motao warmers. I don't know the brand or age as they came with the bike. They are Blue with "Yamaha" on them.

When they are unrolled you can see where the part of the element that "fried" is as it has scorched the fabric. I is right where the ends velcro togeather, and it's melted the velcro.
Might post pics when I get a chance.

Had same problem. As long as the element is ok, then get a clever person with a sewing machine to patch and repair them. They'll last years. Turn off your warmers when not in use. Ensure they're fully stretched when switched on. Ensure they're not rolled up until they've cooled down a bit.
