How long does it take for tyres to warm up?

[LordShaftesbu...]

I've been riding about 3 years now, but it was only on my way home tonight that I managed to absolutely scare the living shit out of myself. Taking a left at an empty roundabout, gently upped the throttle like I normally do on the way out, only this time the back of the bike is suddenly all over the place and the handlebars are slapping like I've never experienced. It seemed to go on forever, I remember thinking it's either going to stop now, or I'm off ... oh, it's not stopping. I was absolutely certain I was coming off. Luckily it all seemed to die down of its own accord.

I was thoroughly shaken by the experience - straight afterwards I thought I could feel something wrong with the back end, some kind of weird wobble. I stopped to check to see if I had a puncture but it must have been my paranoia because the back tyre was fine. The only think I noticed was that it was virtually stone cold. This was after riding for about 20 minutes at about 40mph. I'd say ambient temperature was around 10-15°C, so quite warm, and the road have been dry all day.

I'm sure I've been able to get away with more throttle doing the exact same thing before, so I guess what happened is I just used a bit too much power while leaning over, and while the tyres were still cold?

So my question is, to prevent this happening again, how far/fast should I go before my tyres are safe? I was riding a Street Triple on BT-016s, if that helps.

Weird how they are stone cold, After about 10 mins mine are very warm to touch and I can push the bike hard.

Depends on a lot of factors.
Can easily be riding at a relatively 'rapid' pace on track and still have the tyres pretty much stone cold when you get back because of the wet, cold, etc.

I like tyre that still give good grip from cold.

When i had bt16s on my old gixer they took an age to warm up properly

Get some better tyres.

Mine warm up enough after a couple of miles It also gives the bike a chance to warm up.

After that it is play time

How do tyre pressures affect warm up time? Would reducing the pressure help?

[.Bishbash.]

Don't listen to JD he only likes to warm the middle of the rear tyre, no other part.

Yeah, lowering the PSI in your tyres can make them warm up quicker. More surface area I think, I could be wrong, it's happened before.

Get yourself a set of Racetecs, never ever had a slip on one of these tyres, I highly rate them.

If you weren't going silly with the throttle then have you considered that it might have just been something slippery on the road instead of a problem with the tyres? Also, what about your suspension?

Just got home after taking the same route as yesterday, only this time in daylight. There was a large patch of what looked like white gravel or maybe salt at the edges of the road, exactly where my wobble started. I remember my tyres were covered in white speckles so maybe that's the explanation.

I'd have thought lower psi would warm tyres up quicker cos it would allow them to flex more ...

There was a test done in a bike mag a few years back on different tyre charactersitics.
One then was weird was how weaving left to right will not warm a tyre up. The best way to warm it up is by hard acceleration and braking.
Weaving side to side did hee-haw to improve warm-up times.

Lower pressure to worn the tyre is not recommended.

When you lower the pressure the centre of the tyre will not contact the road properly and this will cause the tyre to lose grip.
Run the tyres at the correct range.
Tyres set with cold tyres.

Roundabouts are a perfect place to have an off.

The road surface could be worn/polished due to heavy use.
The road could have spilled fuel on it.
The road could have a coating of tyre rubber from other vehicle use.

Motorway slip roads off roundabouts are always worth caution too.

Thanks man.

Offtopic, and I think I've asked this before, but what is WALLOPER? Every time I see it I think I've seen it somewhere before, but I've googled and googled and can't find anything. It's doing my head in!

OK, and married to the Cyborg Name Decoder you get your name. Weird, I must be thinking of something else ....

from what i understand about the pressures are that you want a specific pressure once the tires are at the optimum temperature range. the only reason you need to alter the pressure are to either speed up/slow down the warm up speed (but overall i think this will affect the temp at its optimum) and alter the pressure at cold depending on the ambient temperature.

i know a group who take a car racing and the guy has a list of ambient temperatures and road conditions and from that he will know what to set the tires at at cold and after a few laps the tires are warmed up and the pressures correct.

but unless your on a track its not worth changing the pressures. your tires are for road use which means they will warm up how they need to for the road and probably not take too much of a beating. when your on a track tires can be a completely different story.
