bald rears after 7500 miles!
 
ventus v12 255/40/19 front 305/30/19 rear. alignment done when had 2500 miles on them all in specs. did oil change and found left rear completely bald 0/32 inner most tread, 2/32 center 3/32 outer. right rear 3/32 inner 4/32 center 4/32 outer. fronts still have 7/32 everywhere both left and right.

15/20 spacers front and back.
SPC kits front and back
BC racing coils lowered 1/2''

never tracked just DD mostly highway too. cannot figure out how in the world these tires burn out in 7500 miles. any feedback appreciated.

I'd take some more camber out

It's probably a toe problem as well

Hi I just checked the file I had from alignment 5K miles ago:

fronts camber= -0.4 both sides toe =0.08 both sides
rears camber = -1.8 both sides toe =0.18 both sides

can't tell what's wrong...

I have 6700 on my stock tires after 10 months and they hardly show any wear. It's either the alignment or you do a lot of hard driving with the anti-slip deey-bobber turned off.

I'm jealous =(
my last alignment was only 5k ago and all checked out. after that I can't think of anything that would make it deviate from that.
I don't do hard driving either, not an aggressive driver. My anti-slip light probably blinked once or twice in wet rain but that was about it....

=(=(=(

My toe was out of wack and it killed a brand new set of tires In about the same amount of time

Had the same issue recently, had an alignment done close to specs, but within 7500 miles ruined 2 two Invos. My camber and toe were extremely screwed up, just had an alignment done and my toe bolts were coming loose for some reason.

Go get another alignment. See if something slipped. Maybe go to a different shop in case the alignment rack at the place you originally went was out of whack.

Hi everyone I put on 2 ventus 285/35/19 rears this time and had alignment checked again--both front and rear toe were just a tad too much--do not think that will catch the extreme burnout like I was seeing though. Camber was on the spot. anyway, hopefully this new set will last longer.

yah, more of the latter problem... thought those hankooks last like 30K miles or watever lol...

Did you leave your car at a valet or at the dealership by any chance? They love doing burnouts when the customers aren't looking.

kenchan 04-28-2014 04:48 PM

i think burn outs leave a tattle tail sign?

Pics of tires would be great...most likely a combination of your driving characteristics and the rear setup.

Since I'm no billionare, I keep on top of my psi's and allignment...monthly

Yeah it doesn't take much, if you're on the hwy a lot the rears will ware on the inside, I normally get a summer out of the rears, running the same set up as you size and brand.
I also have mine flipped from side to side half way through summer.
