Alignment for lowered suspension
 

Hi

I have a lowered suspension, my tires are wearing out more on the inside

what are the correct alignment settings to prevent this

both my front tires inner thread was worn out, I have been rotating them every 5000 miles

please help

sounds like your alignment is toed in. Did you get an alignment after lowering the vehicle?

get an alignment.

yes I have got alignment done 3 months back, local mechanics don't know shit and what settings to do for lowered car

the car has been lowered for 5 years now

How low are you? Got any pics? Your camber could be too negative...

see pic,

[ Your camber could be too negative...]
could you explain and whats the solution ?

camber would not cause excessive tire wear, common misconception.

bump

It would cause uneven tire where. Toe in and out would cause excessive wear, yes, but it shouldn't cause uneven wear, unless the camber is off as well.

OP a picture from the front and back would be better, difficult to see toe and camber issues from the side unless they're über dramatic.

I had the same problem with my local shops, the reason is because they go by what the computer says and they freak the hell out when the computer starts bitching that the car is outside of it's tolerances. Whereabouts do you live (zip code), I can help you search for a shop.

reread the OP's posts, he explicitly is mentioning that he has severe inner tire wear... this is not caused by camber.

OP. Putting things aside such as ride quality and handling characteristics, If your ultimate goal is tire life then your alignment numbers for camber and toe want to be as close to 0 (zero) as possible. That being said, it is not optimal from a handling and drivability standpoint to use those numbers.

Just judging from how low the car is in that picture, Im betting you are looking at at least -2.5 camber if not more. Chances are you wont get much better than that without either installing a radical camber kit or raising the car's height up.

When it comes to specialized alignments like this, the red-green arrows in the alignment mean almost nothing. You need to have numbers to give to the alignment tech and should have a good understanding of what the numbers mean.


Paimon, As much as I want to back you up because I know that you know your shit, I must disagree with you on this one. Im going on 11 years in an independent tire retail, chassis service, and alignment shop. I diagnose and repair unusual tire wear and alignment issues literally on a daily basis.

Toe in will create outer tire wear. Toe out will create inner tire wear.

A chunky combination of toe out and a too much negative camber will cause excessive tire wear. Although, even if toe is set to zero, excessive negative camber will cause uneven tire wear on the inboard side of the tread. It wont be as quick as toe out, but it will still happen.

OP. Do some research to build up a bit of knowledge of what the numbers mean. Some of the geometry can get complicated, but for your purposes, you can keep it simple by just learning the big three. Caster, Camber, Toe. 20 mins worth of reading should be all it takes.

After that, do an advanced search for thread titles with the phrase, "alignment" in it to see the numbers that others are running with a similar stance as you.

Then go back to the alignment shop and tell them what you want done, knowing what is possible with your setup. :)

ah looks like the misconception was on my part then! I was under the impression that a toe in would cause inner tire wear since the angular forces on the tire would be towards the center of the vehicle. Thanks for the correction.

My apologies to the OP and tcole for the misinformation

hey thanks guys for replying, I will get the alignment numbers and do some research

I live in San Francisco,

here are some more pics,
it happened only to the front tires though back ones were slowly wearing more on the inside

i take sharp turns all the time and anyone would assume it would wear the outside of the tire
