I'm running 0 toe right now and my inside of my tires are already wearing after 5000 miles. Which way do I need to go? Toe in or Toe out? Rear tire wear is excellent. I have 33,000 miles on them and still are not to the indicators. Any help would be appreciated.

 

If you are at exactly 0, then that's the path of least resistance. If you go in or out, you'll get more wear. IIRC, toe in gives you more stability at high speeds, toe out gives you better response and faster turn-in.

Where are your tires wearing?

 

There isnt much else you can do. These cars are known to wear out tires.. You say you have 33k miles on a set of tires already? You're already at almost twice the normal life of a set of IS tires.

check out this thread I started some time back. It should give you all the info you need. Mine is the first post and you can see the PDF from the dealer. I did lower my car if you did not with yours.

 

Thanks passnu2, I think I remember a while back that LowBuxracer was actually getting wear on the outer tread. Don't know if it was the fronts though.

 

Yeah, it was the fronts, but it's because I was doing a lot of on-ramp driving and pushing the front end hard.

If you set to zero static toe and still get inside edge wear, you need more toe out. Dynamic toe goes toe in because the tie rods mount on the front of the suspension uprights, so as you apply force moving forward and the suspension "sets back" the tires get pulled slightly inward creating a slight toe in. To counter it, you'll need to go slightly toe out. I'd try 1.0 to 1.5mm toe out, but no more than 1.5mm for sure.

Any decent alignment tech (no, not some rack driving monkey, but someone who actually understands suspension) should be able to look at your problem and make adjustments to correct it. It surely isn't rocket science.

 

^^wouldn't this be the opposite? so if you had slight Toe-in when you move forward the wheels would straighten out? This is how I understood it and all the info they showed me at the dealer when they did mine after I lowered it unless I have it backwards.

 

your welcome. hope its of help

 

The control arms push backward when the car moves forward and loads the bushings. The tie rods attach to the front of the upright (actually the tie rods attach to the front of the lower ball joint assembly which is bolted to the upright). As the upright moves back with the control arms, the tires turn inward. If the tie rod mount were at the rear of the upright, it would toe out dynamically.

 

^^thank you...

 

Thanks Lobux. That makes sense since the alignment range that Lexus has tend to be shifted to the toe out. I'll have to start flying around on-ramps faster to even out tire wear.
