Mi front tires wore down completely with 4,000 miles

[rockhounds]

I really need help guys. I got my car aligned few months ago and since then, my front tires have been wearing down too fast that it looks like slick now. The rear tires are like new since my 370Z Nismo is 2010 and has only 4,000 miles. I took the car to Nissan for re-alignment and they said the following:

Front Camber: -0.5 -0.9 before and -0.5 -0.6 after.

Front Caster: 4.8 -4.8 before and 4.6 -4.8 after.

Front Toe: 0.44 -0.72 before and 0.05 -0.05 after.

Rear Camber: -2.3 -1.2 before and -1.6 -1.5 after.

Rear Toe: 0.05 -0.48 before and -0.09 -0.09 after.

Would you think that these mismatching numbers are related to the issue I'm experiencing? I'm worried about replacing the front tires and the issue comes up again.

Thanks for your help.

Your front toe looks like it was way off. That would kill your tires pretty quickly.

Id like to know how the hell your toe got off that bad in the first place having just stock rims, toe rods, and camber arms. Bad toe is what will destroy a tire though so yeah thats whats causing your tire wear.

That front toe is nasty tho.

I'm surprised you could even steer the car with the toe that far off.
I'd sure make whoever did the alignment pay for new tires. They obviously didn't know what they were doing. They either mis-aligned or didn't tighten things down after they did the alignment. Either way, they screwed up.

wow...did you run over a cow or hippo?

Was it a Nissan dealership that aligned your Z or another shop?

[kenchan]

why are you showing negative numbers on the AFTER? negative toe = toe-out.

you need positive no's...

i think your thrust angle is screwed up still... wat was the value of that?

Holy toe batman!

I agree it would be the toe. You want negative toe because on a rwd the toe will change toward positive when the car moves forward. If you can't get the alignment to oem setting it may mean something is bent and need to be replaced.

Negative toe means toe in, wheels point in
positive toe means toe out, wheels point out

Hmm I guess for some people a picture helps.

toe in - Google Search

yah, i know wat a toe-in condition is. thanks for the link.

basically our suspension requires toe-in for stability. the toe goes out wards (negative) when suspension is compressed. some folks use toe-out condition on purpose for quicker steering input response, etc. but for normal driving you'd probably want 0.02 to 0.05 degree toe in on the front per side, about 0.05 to 0.12 on the rear.

but that's just me.
