ok i have had these hankook v12 evos for about 3k miles now and they are doing this weird thing where the front driver side is wearing away at the corner. Im thinking from hitting hard right turns that the tire is rolling over to much and heating up the part in between sidewall and tire tread. I was driving a few months ago and such a long shred of rubber came off i had to stop and pull it off to continue driving so it wouldnt be slapping around my fender ect. It was a thin long piece, probably 8 inches long at least.

NOTES:
-ONLY ON DRIVER SIDE FRONT, THE DRIVER SIDE REAR BARLEY DOES IT AND BOTH PASSENGER SIDE TIRES ARE FINE.
-tire size 235/40/18
-oem USP wheels 18x8 et 43
-10mm h&r spacers all around
-regular 4 wheel alignment done after i got tires(no computer)
-Front psi starting at 35 cold but keep them more at 37 psi cold now
-Rear started at 35 psi cold but have them more at 39 psi for more rear end response(stock non sport sways ha)
-good control arms, sway bar links, good aftermarket suspension


driver side TRE is cracked and steering HAS felt loose lately. so maybe that could have something to do with it. ALSO, since i was sold a couple bent wheels (USP's). One that was horrible, but had fixed and still getting a little shake on freeway not sure which one it is but its on the back im pretty sure.

many pictures..

looks like it's rubbing. check your fender liner for rub marks. 235/40-18 is pretty big.

i have a 2 finger gap all around

i really dont think i could be rubbing. never heard it rub once since iv had this setup. why would the rear driver be doing it as well then? its barley peeling like the front but it will peels a little bit here and there.

Is it possible i could be rubbing at high speed cornering? say a sharp 60 mph turn?

It's possible.

That tire looks like it was cut by sheetmetal. Rub some soap or white shoe polish on the inner fender and go hit some hard corners. Then check to see if the soap or polish rubbed off.

So why is my rear drivers side tire also having the same problem. (not nearly as bad tho)

this picture kind of explains it. you can see that the tire is not sunk into the fender well, it is at the same depth as your fender. So during hard cornering, your suspension compresses, your tire meets your inner fender, slice!

Looks like excessive body roll. Try the shoe polish trick first, real simple

ill definitely have to try that first. maybe tomorrow.

no i wouldnt call it squishy, Its pretty much brand new suspension. Bilstien shocks and vogtland springs. Id say its pretty firm actually

you might be right, but i really just find it hard to believe that my suspension compresses that much for my tire to hit inside my fender. There not stiff race springs or anything but shit, there vogtland sport springs that are definitely stiffer than stock sport springs.

kind of an issue iv had since i got these new tires and wheels.(coming from stock 16's with worn out 205's.)
It seems as if my car has more body roll now at high speeds and seems to be a little "floaty". I was hoping a rear sway bar in the future would help. Also thats why i boosted the pressure up a bit thinking i would have a little more response and would cut down on the tire wearing like this on the edge from keeping the sidewall more stiff...

^^^

this could also be due to the fact that im running a heavier wheel/tire combo, taller tire with more tread so my center of gravity is definitely higher than it used to be...

Did you change the overall tire profile? Is the sidewall taller than the stockers were? Have the tires done that since you've got them? They may just be a defective set. There are definitely some variables to look over.

It happens. This car is on race suspension and it's tucking in the corners

Can you take a left hand turn as hard as you take a right?

i went from stock audi wheels, 205/55/16 to 235/40/18. The overall diameter of my new setup is around 1/2 of an inch taller but a lot of people run that tire without problems including my neighbor with 2.8 sport package a4... the tires starting doing it after a month probably. and i drive my car hard.

true.

haha im guessing i can but i mostly am taking right hand turns because of all the awesome on ramps we have down here in SD. where the good left hand turns at!? lol

Fender rolling would help a lot in the front. I had to do it with 235/45-17 which are the same outside dimensions as yours. Later I ran 245/40-17 with no rubbing.

Your center of gravity didn't change. They are unsprung weight and their cg is still centered around the hub.

H-Sport sways are the shit.

Left turns are the off ramps.

I run the same size. It takes a corner at 50mph with 5 people in the car and a bump to get mine to rub and im lowered a little.

what offset are your wheels? does it rub in the back or the front?

do you have spacers?

ok well i came to the conclusion that my tires are rubbing, barely, but are still rubbing and high speed cornering and only on the driver side... my front a lot worse then the rear and definitely need to fix this. the question is, how do i fix it? how do you roll that inside top part of the fender?

it is rubbing at the highest point of the fender if you are looking at the car from the side. and it is rubbing on the inside of that part of the fender...
so this means i wouldnt rub if they werent so flush/even with the fender, and closer in in how a higher offset wheel is, for example a stock wheel with et43 vs my et33 setup.

my wheels are et43 with the 10mm spacers that are on there now. Im thinking they might not rub with a et35 offset. But im not sure if that would be enough and if they would rub or not in the rear... the clearance is very close in the rear with that suspension bar that hangs over the tire... But im thinking there are a few mm to spare, the fronts definitely have more room from the tire to suspension parts then the rear...

what do you guys think? sell my spacers and get 8mm and see if that fixes it or just pay to have my fenders rolled? also, if rolling fenders is risky i wouldnt want to do it. I have heard that if you dont do it right you can crack old paint ect.

What do u guys think?

again, my setup

vogtland sport springs(2 finger gap all around)
235/40/18 ventus evo's
18x8 USP et43
10mm h&r spacers
