tires breaking loose on RWD common?
I have Continental DWS tires with plenty of tread left. These are supposedly decent tires.
But with light/normal throttle from a stop, I chirp the tires half the time before traction control kicks in.
Not sure if the tires have less grip or the road is dusty, though the road does look clean.
Anyone with expensive michelin tires often break the tires loose?

What car do you have? I had Conti DWS 06 on my GS430 and never had them chirp with light, moderate, or even heavy throttle. I had older Michelin summer tires on my GS430 that were pretty worn and I definitely had some traction issues on them in wet weather, particularly with turns, I was making a pretty sharp u turn one time on a wet highway and slid and almost did a 180 with traffic coming, scared me to death. Once I put on some Kuhmo Ecsta ASX never had any traction issues and were a lot smoother too, almost day and night difference, Conti's felt about the same.

Alignment is usually not an issue with traction problems.
One thing I can think of is that the TPS (Throttle-Position-Sensor) may not be working properly....sending a signal to the computer and fuel-injectors to inject too much fuel when starting up from rest, creating too much power in the engine.

The two possibilities are over-aggressive throttle application by the driver or a mechanical malfunction. No tire in this category would chirp if taking off normally and everything else was working.

^^ I agree with mmarshall's suggestion. If you can use a multimeter and the TSRM for your Lexus check the voltage rages for your TPS sensor or TRAC sensor to make sure one or both are operating within OEM spec. Or take it to a mechanic to do the same.
It does depend on the car but it shouldn't happen unless you really tried to push the car full throttle from a stop. I've done it occasionally in a 290hp '99 LS400 by trying hard to but it wasn't much of a chirp. TC always kicked in after one second. The open differentials in most Lexus vehicles make this easier to do but for the vast majority of owners they won't be pushing their cars in such a way for it to make much difference. You have to deliberately try hard to do this unless you have a very modified suspension setup (or non-factory alignment) that has taken the car out of its ideal geometry. And even then, TC kicks in to limit power and further loss of control.
I have to deliberately try to do this in my car with no factory traction control. The only exception is very slick roads where tire to road adhesion is naturally lower. Even then, with mindful driving as to the conditions it still should not be easy to break loose.

If that is the case neither of those cars are very powerful enough to be regularly chirping tires on Conti DWS though the 07 GS350 did have some pretty aggressive gearing down low.

Turns out all my tires lost 6 psi over time, and were underinflated. I just read that contributes to chirping and slip from turns.
and I have Power ECT mode turned on all the time in my GS. so it's jumpy with the throttle.
Inflated all back up to 34psi, we'll see.

Some of the automatic pressure-indicators in newer vehicles will also sometimes take a minute or two to stabilize when the tires first start rolling....you might not get a perfectly accurate reading from them at first.

This all depends on the car. My little 2wd Tacoma, 2.4 liters of fury, its stupid easy to get wheelspin from a dead stop, especially in the rain. If you want to get the jump on somebody at a light, it involves wheelspin, no way to take off quickly in that truck without breaking traction.

I dunno I have Pilot Super Sports, are those expensive? And I dunno what kind of car we're talking about so I figure it's not material. I will say yes, if I accelerate even mildly, my traction control kicks in, very annoying. Also, it has a hill holder that is quite annoying as it grabs the rear even when not on a hill for a few ms. I would disable the traction and stability, but that's also not recommended by the mfg and forum, so can't win....

I know my truck likes to get freaky in the rain. Or if I'm climbing up a steep gravel road.
.....or if I ****** stomp on the pedal.
