Default corner balancing and tire wear

Ok guys, heres some background info: 01 prelude with azenis 215. Size: 215-45-16 on a 16x6.5" wheel.

I installed GC/konis in october of 04. I set both the front and rear to have the same thread count between left and right. The rears were mostly even but in the front the driver's side sat about 1" lower than the passanger's side. I eventually evened the front out but the front right perch was lower on the sleeve than the font left - yet the car sat even. A few days ago I rotated my tires and I noticed that the right tire was much more worn than the left. Is that because since I lowered that side more to even the car out, it has more weight on that tire therefore causing it to wear faster than the left? And does that mean that the car is supposed to sit unevenly in order to distribute the front weight evenly between left and right? Its a daily driver so I wasn't planning to corner balance it on scales until I was ready for new tires or started doing HPDEs again. Thanks for any input.

Peter

The engine weighs more then your tranny, therefor your drivers side perch will sit differently to even it out. Because the car isn't corner balanced you are placing different weights and different stresses on each corner. This causes uneven wear.

no, not quite.

you didnt mention if you got an alignment after you got your final ride height.

toe alignment changes when you lower the car. you also lowered the car unevenly, relatively to the start. thats why you have more uneven wear on one side.

you must check and adjust your alignment everytime you change ride heights.

then there's the problem right there, get an alignment, issued solved.

tire wear can also be affected by driving habits (more hard lefts than rights, etc), rotate your tires often and make sure they're properly inflated

I did get an alignment after I had the car set so that the left and right sides were even. However I did not realign it when I lowered each corner the same amount shortly after that. I just want to be clear that Im not talking about camber wear on the tire, im talking about the whole right tire being more worn down than the whole left tire. Ill try to get pics up later.

well it has nothing to do with corner balancing.

not aligning it again after you messed with the ride heights is still going to cause toe misalignment, which causes accelerated tire wear.

but what Im wondering is why the right tire wore faster than the left when they were both at even heights. Could toe have been bigger on one but not the other in this case?

Lowering a wheel relative to the others actually takes weight off that tire. Raising it adds weight on.
