Hey everyone, for the last two years, ever since I got my rims 18x9" 20 offset with a 255/40/18 rear and 18x8" 20 offset 245/40/18 front. My rear tires have always been wearing weird like the pics below. Now my question is why lol. I have gotten like 20 alignments and two sets of rear tires in the last two years and i need new tires soon and before I destroy another set I was hoping someone on hear might know something to prevent this. The rear camber is at -1.5 degrees on each side, and i've tried the toe at 0.04, 0.07, 0.08, 0.10, 0.12 and all of those settings wore like this. the only time they weren't wearing badly was when it was out of spec at 0.15 and the shop convinced me to put it in spec and then it started wearing like crap again. Is it because of offset, (maybe needs more toe in because of the bushings) or the tire toyo t1r, or the tire size(255/40/18 to small for 9" wheel? my stock rims and tires never had this problem. please what do i do? and what the h#ll is causing this?

 

looks like you need to adjust your toe settings.

 

feathering... its common is Z's every1 Z has that problem.. to fix that is loads of work

 

what kind of work? and is there a better toe setting that might minimize feathering.

 

have you had all 20 alignments done at the same place? if so, I would say go somewhere else....

0.0 toe

 

Looks like too much neg.camber to me.Only too much toe out could cause that much inside edge wear.

 

I have tried multiple places. and -1.5 camber is the recommend camber setting from nissan, so i think it is a toe problem. i agree with foreveryyoung "Only too much toe out could cause that much inside edge wear." so should i sets it to more toe in then factory" like 0.15?

 

Too much toe in will feather the tread worse.I think the wider tire and 40 sidewall will blow the stock camber settings out the window.There is less sidewall flex to allow the tire to sit flat on the road,hence the excessive inside edge wear.Yuo need to plant the tire more vertically because of this.I would try for 1/2 of the neg camber first and minimum toe in.

 

I saw and chew the outer edges of the front tires from autocross. Aggressive driving will have similar effects on all tires.

 

Man,you've driven it so hard you bent all the treads
