How do you warm up your tyres - on the street and on the track? BTW yesterday I found an article on the Internet with some tests which prove there's no point in making twisties in order to better/faster warm up your tires.

How to warm up tyres

I swerve left and right in my lane to make a large contact area on the tires, sort of slalom down the street. I ride conservatively for a while before making any sharp turns.
I'm not sure but I sure could have used it yesterday. I hit a 180 degree freeway on-ramp at about 30 mph within 1/4 mile of my house yesterday morning and the rear tire started slipping out from under me. Luckily I maintained constant throttle application and put my foot down to keep the bike from going down.
Maybe I should buy some of those tire warmers you see trackside for use before my morning commute!

almost everyone on the track uses tire warmers due to the type of tire that they have. A street tire will heat up on it's own after a couple minutes of riding and weaving has no measurable effect on that, other than it gives you a feel for how the tires are gripping that day.
The spot I park my bike is very sandy, so I weave a few times in the street to scrub the tires off. By the time I can go above 30 mph, the bike is completely warmed up as well as the tires.

I ave heard that this is a bad thing to do.. be carefull, or maybe im looking to deep into what you said

yes it is the deformation of the tire from flat to round that warms them.
I weave/sicssor for fun on my bike, not to get them warm. It also scrubs off the old rubber and puts a fresh new layer down on the road surface.

Street tires will warm up fast so long as it's not brick outside. Tire pressure will impact tire temp. as well, from what I understand.
Can you post the link?

Not to thread hijack but it's related...
How long would you say it takes for the stock tires to warm up under normal city riding conditions?

Here is a good one too. Its 70 pages long though and takes quite a while to read, but its worth it.

From track days i've been told that about 10km of riding (6-7 miles) is enough to warm up normal road tyres. So take it easy when you're just pulling out.
As to weaving, i do it standard every day, not so much for the tyres, as for me. It allows me to find my limits for the day.

On the race track it's NOT only the tyres that need warming but also the engine, oil, brakes and (yes you guessed it) THE MIND.
So actually the most effective method is simply riding slowly and carefully for a lap or two, and letting everything warm up steadily.:rockon:

Isn't a hot lap just an aggressive, mucho lean, high speed weaving exercise? They used high performance tires...I bet weaving hard on coldish street tires with pressure below 35 will help them on their way to "temp" faster than a straight line would...it has to, no?

Nope, leaving the bike in the sun has more effect than weaving.

I just do some weaving across the road. Its not a big deal because by the time I get to anywhere that needs the grip of warm tires they are warmed up whether i try to or not.

"nope" what? I read the thread too. You're missing my point....

Good read, thanks!

The amount of pressure in the tire is directly proportional to the ambient temperature at the time the pressure is measured. For example, suppose you live in the valley where the ambient temperature is 100 deg during the day and you air up your tires to 40 psi in anticipation of heading up the local mountain the following day. The next day your at the top of the mountain and the ambient temperature is 60 deg., you measure the tire pressure and it reads 36 psi. The rule of thumb is for every 10 deg. change in ambient temperature results in a change of 1 psi in tire pressure. Of course this means the pressure change goes either up or down.
So what does this have to do with warming tires? The less pressure in the tire and the more a rider(s) weights combined with the temperature of the road surface all determine how fast the tire warms.
A reduced tire pressure causes a larger foot print in contact with the road making the tire flex more which generates heat and this heat will tend to raise the tire pressure slightly.
So if you really want to warm your tires, the ideal way would be to let out 5 psi pressure from you tires before you set out and run them 1 or 2 miles, then stop and increase the pressure to normal.
This is an interesting article on the subject of tire pressure and temperature.
