I am going to scan my alignment results and post it. I am wondering why I had severe inner wear considering that the before and after settings are not a big change.
Now if I compare the recommended settings to the old and new, it shows little deviation....???
I feel like I am missing something.

Hi Everyone,
After much research, I have decided to purchase a set of Conti Extreme Contact DWS 06 tires for my new to me 2010 SC. This is a brand new tire released in May of 2015 and it is said to have all of the attributes of the orginal Extreme Contact DWS plus some additional attributes. I will let you know...................

Alignment specs- more lies from bad mechanics?
Not all shops (or dealerships) will reset your camber to anything other than factory specs. For some reason, Lexus set the camber from the factory so that it causes excessive tire wear on the inner surfaces.
If you take the car to an independent alignment shop that will use the specs you give them (preferably one that does laser alignment), and tell them to use these camber specs when they do the alignment instead of factory specs and you should be golden. Your tires should wear much more evenly without any negative side effects (other than the steering feeling a bit lighter):
front +0.05 toe and - 0.85 camber.
rear +0.15 toe and -1.25 camber.
BTW ...unless you hit a lot of potholes or bash a curb, you shouldn't really need an alignment that often. You should be able to go for years without one.
Good luck....

Also, in regard to the tire wear issue on the inside, I read on the daizen website that the solution is changing the control arm bushings. Another place I read the solution is to get w camber kit. But on this thread the solution appears to be correct alignment specs?
So is the solution to the excessive tire wear correct alignment specs, control arm bushings, or a camber kit?
Can someone please help me understand??

I have an unlimited alignment plan for five years at Merchant Tires. That's the only reason I go there. Got my conti pure contact tires installed yesterday and asked 'mechanic' to do alignment based on the specs you provided. He said he could not adjust the camber as much as the specs but he did the best he could. I didn't really fully understand what he was saying so I will post the alignment report tomorrow so everyone can chime in!

Good luck, this can be corrected without adding kits or control arm bushings.

All I can say is when I had my first set of Conti DWS tires put on in 2010 The camber was way off. This from the Lexus dealership. This was a CPO car and I only got 18K on the brand new tires because of excessive wear on the inside of the rear tires. I had all the camber taken out that was physically possible. The tech said that it was at the limit and it was the best he could do. I said OK we will see what happens. I got 45K out of those tires and they were worn perfectly. I put the Pure Contact on this time a little over a year ago and had the alignment checked but not changed. I have about 13K on the Pure Contact Contis and they are worn perfectly so far. I think if you come close to what NAmvet and I have as settings you will be OK.
Good luck, this can be corrected without adding kits or control arm bushings.

Still on the fence on what the GOOD setting is. I hear that negative camber must be taken out. The readings below is what the other members are recommending however it shows high negative cambers, should they be close to ZERO?
Left front Camber -0.9
Right front Camber -0.2
Caster Left 8.6 Right 9.1
Toe Left 0.09 Right 0.09
Rear Camber Left -1.7
Rear Right -1.4
Toe Left 0.09
Right 0.09
Am I bonkers on interpretation?

Less Camber means more negative results right?

its very hard to get shops to change setting because of insurance. if they change setting other then stock they will be lie-ble that why they don't want to change it. if you change the setting to more straight up it works but it effect steering. we are watching these setting.

Seems like making the adjustment to the REAR TOE is the most important since OE specs cause excessive tire wear to the inside of tires in the rear... No?

I will ask them to change it to my settings towards the end of the 6 months warranty that I have on alignments.

I think that the rear camber is the issue. I had them move it to the inside of the spec. -.7 adjustment.
I do agree with the rear toe in adjuster upgrade. I have Battle Version -- really well made.

No, toe will not normally make the tire wear on the inside. It causes a scuffing pattern which can be on the inside or outside depending on whether it is neg or pos and whether you have a front wheel drive or rear wheel drive. What is being described here is normally associated with camber. You need to check the rear thrust angle also. This can cause problems. Mine was way off when I got it from Lexus (CPO)

Hi Iolmaster,
Dio you like the Conti Pure Contact or the Conti DWS better and why?
Thanks,
Tom
