i just went to Toyota SC. Showed them my exhausted tire that is with the car from day 1, which is about 1 year ago, they said they will charge me for alignment but will replace the tires for me for free.
after i come home only i realize, why I am charged if seems they admit it's part of the problem.

any1 encountering vios J with goodyear GT3 exhausted after 1 year? it's only at front wheels edge. heard they r going to change it to GT5 or some xx5.

my wear pattern is only at 2 edge of both front wheels. at first i thought i didnt fill up the air properly n therefore hv this kind of issue. but after checking with SC, they quickly give a conclusion that can change for me without charge for the tyres and only charge alignment which makes me feel kinda weird. i hv been asking SC to adjust suspension noise at almost every service appointment. when they mention tightened screws, noise problem get better and then eventually will return after a period of time.
like u said, another possibility is i take corner too fast. but in terms of speed, unless vios j is so imbalanced, dont think the tyre wear out so fast as the fastest i take corner is 60km/h, which is only at smooth curves. but i do hard brake at times, but i feel the wear out pattern is strange.

another phenomemon i still fail to convince SC to check for me is my front part of the car vibrate when breaking from 80/100km/h to 60km/h. the vibrate only happens at range of 65-60km/h and none at braking after or below. now i m hoping changing to new tyres will solve this, or mayb not.. waiting for the sign to bcome more obvious n consistent.

thanks for ur reply. however, strangely the SC guy mention it's common problem for Goodyear GT3. Therefore he mention i need to replace them. I did asked SC b4 if i need to rotate the tire at the 1st 10k km service but they mention no need. Earlier this week was only 20k km service. I agree with you that the wear is cause by myself if it's not a bad batch of GT3. For the tire pressure part, I filled up according to the manual book. After I found out my tyre wear pattern only I fill up +5 psi than the recommended numbers stated at driver side A pillar, which didn't help in slowing the wear. Waiting to get reply from SC upon availability of replacement tyres.

do hope to check with other J owners. Talked to SC again and this time the information they give is the tyre design spec doesn't match vios J. i still couldnt get written log to persue this complaint. they promise to replace in 1 or 2 weeks time, which i m yet to get confirmation.

i wouldnt bother sending for outside alignment or balancing as this would give them an excuse that i tempered ther car setup n thus voiding my warranty. for some lucky ones where their GY GT3 are doing fine, i guess ours could b a bad batch of tyres, which UMW seems to b covering up. i m not happy with their decision to not releasing this important piece of info. Lifes are on their hands.

my J registered end Oct 2009. Manufactured date should b aug/sept 2009. how about urs?


edit: for those affected, the tyre hv a tendency to skid at wet road. pls b informed.

thanks for ur input. which model of vios r u driving currently?
i think wat ur trying to say is check alignment since u mention u get free alignment adjustment from SC. that i understand wouldnt void the warranty. agree with ur view regarding the warranty. i just get too skeptical with the fellas in SC.

michael, read from ur previous post that GY NCT-5 is rubbish. Toyota SC just replaced my GT3 with NCT-5 due to the tyre eat 1 side problem. Is it really that bad in wet or downhill? Reason being, thinking to sell them off when it's still new now and get a new set of PP2.
1 funny thing is i hv to pay for the alignment/balancing to get my tyres replaced. n also they refuse to replace the spare tyre saying it's not "on the wheel".

were ur old tyres goodyear gt3? the RM7x is the cost of tyre or cost of balancing?
there's a silent replacement program for owners with an affected batch of GT3 tyres.

my 08 vios J is doing the same. i thought only J has the least sound proof. I've forgotten if i felt the same when i first collected my car. only thing i know now that the road noise is so loud that i need to push up radio volume. i remember the radio is visible at volume level 10 to 13. but now i notice i need to go 20 to 24...

recently, i notice when braking there's a krak noise. send my car back twice n the conclusion is need to skim the brake disk. is this a common problem? i worry the problem will still b there even after they skim since they didnt get it right after 2 service center visit.
