overheating wheels?

hi to day i was riding a normal park skateboard around the hill near my house and i started carving down the hills and after a while the wheels got really hot and after a while the wheel would hardly  even grip the road on tight turns the only thing i can put it down to is the heat in the wheels does anyone have any other ideas.

Billy, you are busting out some seriously awesome advice here!

 

Mojo, PU is a thermoset so I wouldn't expect so, or if there is an effect it should reverse once they cool.....although there's dyes and fillers and all manner of funk mixed in so it's possible heat could have some permanent effect. The main thing that is likely to get them is gradual degradation due to moisture and age. Over time they'll start to oxidise and UV will cause chain scission. PU is slightly homphobic hydrophilic (from memory), so water can potentially affect its structure too, but not enough to worry about in the short term.

Someone with more hands-on experience with PU may well come along and correct me. I never had much to do with them.

also, you will definitely get a tonne more traction of you lube up ur bearings with super glue. it makes them run super smooth and fast. split duro wheels also help.  you want two 100a sergio yuppie sliders at the front, for maximum roll speed. and two 72a flashbacks for awesome grip at the back...you also might want to run a 0 degree baseplate at the front and a 65 degree base plate at the back.

i do know about friction that wasn't the problem it was the fact that after the heat the wheels actually lost grip on the raad

You were riding small hard wheels down a road. A little thing named friction made them heat up. Why does this discussion exist? It is not bearings, or blown cores, just friction.

 

If you are old enough to be online, own your own skateboard and form a sentence with a keyboard and you still don't know about friction then the Australian schooling system is deteriorating faster than we thought....

I take back the mean-spirited things I said about your question - the effect of heat on grip is actually a valid thing to ask whether they're park or downhill wheels. I'll have to get back to you on that.

Road temperature does play a roll in how grippy or slidey a road is. Hot days are different to cold. Suppose the temperature of your wheels would have an effect too. Get off those hard little wheels and get some grippier wheels. Problem solvered.

This thread reminds me of that scene in Clerks,

'Whad do you mean theres no ice? you mean I gotta drink my coffee HOT???'
