hey, my tire are worning in the middle,

this can be cause by heavy acceleration right?


tire pressure are allright

 

Sounds like too much air pressure.

 

i think the tire pressure may be a little high so the middle bulges out some, release some air

 

could be too much air....

 

Do you have stock tires or did you put different ones on? If you changed tires, the new ones might be built for a slightly lower PSI. Unless you're burning the crap out of them, it shouldn't be noticable wear just from acceleration.

 

usually its because of overinflating but if you say press is ok not sure are you going by the psi listed inside the door of the car or on tire its self?

 

mine did that a bit too, i kept them on the higher side of recommended pressure

 

wear in center = over inflation
wear on edges (both) = underinflation
wear on 1 side = camber

 

What is everyone airing their tire up to? Mine is doing this also.

 

With stock Rossos, it should be at 32PSI I believe.

 

What IS the tire pressure? Check it and post it.

 

32psi is correct.
I remember reading a thread a while back where quite a few people thought 40psi was correct.
one guy even had them at 50.

so yes. I agree.....what IS the pressure.

 

that would be "OVER INFLATION" ....

I do run my rubber at 40psi... I like a nice firm sidewall and "NO, mine are not wearing faster in the centers"

 

Hmm... sounds like too much air to me.

Max tire pressure is not the number you should be inflating to... it's the most the tires can handle. You'll get better traction if you run slightly lower than max.

Mine are at 32PSI.

 

this will also happen if you spin them a lot.

also, what sort of driving do you do?

if you run at higher speeds, the pressure inside will go up. so, operating pressure is a lot more than 32.

try this... drive at like 50 for 5 miles or so... then measure it... then run at your normal speed for 5 mile, and measure again... if it is a lot higher, there you go.

also, maybe your tire gauge is not accurate....

or, make sure the tires arw not installed wrong and rotating in the incorrect direction.

 

i got the stock pirelli, they are at 35 PSI all way around.

i will get them down to 32.

i drive "ordinarly"
i dont beat my car that much,
never done burnout.
hard acceleration sometimes but thats it.

 

MAX pressure on the Pirelli's are 50 PSI

 

mine are at 30psi i believe, well the front tires, and the rears are 32
