Help needed please.... front tires wear fast.

[jnance22]

Hello guys and gals,

I really don't post on here but need some help or advice.

So my front tires are wearing really bad on the inside shoulder on both front tires. The suspension is stock and the alignment set to OEM specs. I noticed they wear about 4 months after I got the car when i was replacing my rims. I put new tires on the rear and they still look fine today and kept the front tires but just flipped them. So after 4 months of having them flipped the inside shoulder wear again. I went and had my alignment check today and it's all in the green. Does anybody have any ideals or had this problem.

The rims

are
20x10 et20
20x11 et40

Thank you in advance any advice.

How many miles is 4 months for you? What sort of tire pressures?

With everything else stock I'd ask the same as Nagare, what pressures are you running? Improper inflation will screw up symmetric tire wear almost as bad as a ridiculous camber.

Should also includes brands and size specifications of your tires.

From those pictures, it looks like the shoulder wear on the tires is the same inside and outside. Sounds like you're running these things at low pressure.

Im running them at 35psi and the out side is like that because i had them flipped. Ok i looked and its been about 5 months so its around 8500-9000.

The brand ohtsu fp8000 and size is 255/35r20, its what was on the car when i got it. I know they are not the proper size for a 10inch wide rim but i didnt have the funds for new ones at the time. I did a set of 255/35 on a 10.5 in the past on a g37 with good wear compared to this.

Best guess is, you corner hard, and they're just cheap tires. And you already know you're using the wrong size tire for the rim they're on.

For cheap UHP SO tires, 8K-9K miles is sort of normal. Get better tires, in the right sizes for the rims, and keep them at the proper PSI, you should be GTG.

I HIGHLY recommend Firestone Indy 500s, they're amazing tires for the money.

What size tire? It looks like you are stretching it out a little, which could possibly put more focus on the outer part of the tires vs the inner part. I'd bet that has more to do with it vs tire pressure.

 

[jnance22]

Both could be very true I just didn't want to invest in new tires if this was going to keep happening. I was hoping maybe somebody had the same scenario i am having. The car was previously repainted but no Carfax on why it was . I was just hoping it's not major front-end problems. Thank you all for chiming in and given words of advice.

They should be able to get what ever alignment you need in the front without much trouble. Will probably need some camber bolts. I was seeing wear like that on mine since it had pretty much camber. Too much camber or/ and toe out can really do this with tires with very stiff sidewalls and a little low on pressure. I had the Falken version of those tires and I needed to have very high air pressure to not see that. Like 40PSI. So I now have my camber set at the minimum with just a 1/16 toe in and having great tire wear. If you have a level stand it up along the tire with the bottom against the tire or rim. Get the level perfectly vertical. Then measure how far the rim is from the level at the top portion of the rim. I like mine about 1/4-3/8. It still handles very good since I have low sidewalls on my 20 inch rims. The bigger the rims the less camber you need and can get away with.

Stretched tires doesn't help either. As you go thru a hard turn the inner sidewall sort of stands up under pressure and makes things worse on that very inner edge. I looked into this alot because I have seen the exact same condition especially on my older G35 which did not have camber adjustments. All I did on that was keep adding toe in until it got better.

When you put rims and tires that are out of factory spec, you cannot use factory spec tire pressure, alignment specs, etc... this fact coupled with cheap tires equals what you have going on.

 

[jnance22]

Yeah the guy at the alignment rack wanted to oblong the holes up top so he could bring out the camber a little bit. I guess my best bet is to try a camber kit up front to bring it out a little bit and buy better tires. Thank you everyone for helping me throw out some ideals.

never heard of ohtsu fp8000... I think thats your first mistake. Also MY PZEROS get about 9000miles before they needed replacement. Rears though. Never heard of Fronts wearing faster than rears on a RWD car.

Those look far too narrow for the wheels. That's one reason you're getting inside shoulder wear. I'd reduce pressure to 30.

This tire is a rebranded falken fk452 which actually is a decent performance tire that has relatively poor treadwear though. I have done both ways of getting the camber correct. Filling the holes if I only need to move a little or the camber bolts. I sort of prefer the filing so I can still use the factory bolts and I can do the math to determine how much to file to get the desired camber. You should be fine after a good alignment and decent tires that are correct size like the others have said.
