tyre not balanced worn out

[nadziad]

can someone explained to me how come the rear tyre not balanced worn out....it like "worn out...normal...worn out..normal" btw im using adjustable suspension. is it problem with my adjustable?

 

[crazykatak]

perhaps,
a picture could be helpful..i cannot imagine which part of ur tyre is worn out or normal wear..

how old is ur absorber?

try jack up & try shacking ur rear tyre, it shouldn't move, if it does, u got bad wheel bearing

just share,
mt mech said, most japanese car, not new car, right hand side camber always 0.5 to 1.0......left hand side need to be 0.75 to 1.25.....it wont makan tayar.....

so, wat is ur camber setting......if its ok like above......check other zth member advised......

last time my tyre also makan tayar.....that time i ask mech to adjust camber to zero.....i thought it wont makan, he explain.....while ur car is moving.....it going to pumpy up n down...bottom of the tyre will move toward the car.....it will makan outside bunga......is ur tyre like that....??

the front tyre is like that...mkn outside...but after rotated it is ok and not touch the middle one but the rear tyre look like it worn out not equally..some place got 'botak' and some place normal

mine absorber is 1 year old...hmm dont know if wheel bearing cam cause these problems

makan inside.....means camber too much.....better check bushing bearing....

another thg my mech said......rear tyre front portion alignment need to adjust towards inside....by doing this....more grip when cornering.....

sifu2, correct me if im wrongly explain....THANKS

 

[kazukimy]

erm, i think u should go check wif ur tyre shop/alignment...or ur camber check,for mine,all 4 of my tyres 'makan' inside...for some purpose,wakaka

 

[mh wong]

kazukimy,
for cornering want grip,,,,,need to sacrified........haha

 

[kazukimy]

wakaka,nah...im driving an old car and im an old uncle,need stable ride to commute,
by the way, Nad, u r driving FF,dun think will makan dalam,u need to look when they adjust ur camber...hmm...

ohh satria neo ke..

okay like this.

first of all

check tyre pressure; front 32psi rear 30psi.

assuming all height adjustment is correct..

you're gonna need negative camber at the rear wheels, -1 to -1.5 degree each wheel ( assuming front wheels' camber is also around the same range as the rear )

0.5mm toe in for all 4 tyres.

front right hand side tyre 0.5mm "toe in"
front left hand side tyre 0.5mm "toe in"
rear right hand side tyre 0.5mm "toe in"
rear left hand side tyre 0.5mm "toe in"

so, total toe for rear wheels should be 1mm "toe in"
same goes to the front wheels. total of 1mm "toe in"

hope this helps.

thanks for these info...btw i also change my rims that use 7.5 inch for rear and 7 inch for front still use 16 inch rims..some mech says i should pump air 32 psi front and 33 psi rear....and the the chamber i didn't do anything to make it "terkeluar"...it it possible these rims can make tyre worn inside?

 

[Supra_Fanatics]

If tyre wear pattern not balance then could be tyre swollen...get it check. If all is balanced then okay xD Then it got to be chamber and etcs like the rest mentioned xD

 

[^pomen_GTR^]

u did alignment/camber adjustment after change absorber or before change absorber last time???


seems to mee like too much -ve camber.....for satria neo stock setup rear camber is -1.0degree if i remember correctly...if around -1.0 or -1.5 still okay...but if -2.0 or more it surely what u see on the tyre
