Did my suspension do this ??? ( Please Look)

[2GturboTALON]

So i decided to go out and check my brakes and see if i needed vented or solid rears for my awd talon, while i was out there i decided to check front brake pads and this is what i saw. I'm guessing that maybe the suspension ate away at the inside of the tire. I had noticed a bit of vibration, but thought i just needd brake bad.

[2GturboTALON]

I'm on 225/45/17 and not lowered. Also i noticed my front tires were slightly overinflated ( about 41-42 psi, and tires are 44 max) a few weeks back and i deflated them to around 34-36 in the front.

Looks like you need to get an alignment. Excessive toe out and too much negative camber can cause that. Inflation pressures of 42 may cause some excessive wear along the midline of the tire but shouldn't cause anything like that.

[98GSXtreme07]

Agreed. I bet your over due on a rear-end alignment. I would go ahead and get new tires or just the one if you can't afford it and get a FULL (front and rear) alignment. I had 225/45 before and never had that problem.

Do you have a problem with your rear-end bouncing all over?

[No_Skillz]

You shouldn't rub with 225/45/17 on stock suspension. I am running 235x45x17 on lowered suspension and I DD fine.

Your problem lies elsewhere. Either cheap tire or bad alignment.

And with AWD, you need ALL 4 TIRES REPLACED AT THE SAME TIME WITH THE SAME MODEL.

I did forget to mention that part. Highly Important! Just saying that if money is tight than do the one, BUT ONLY AS A TEMPORARY!

Thats weird, I had the same exact problem. The tires were not cheap tires at all! However, I just bought some new ones, and the problem hasn't came back. I have been checking the new tires and no sign of unusual wear.

Come to think of it, my rims were bent to hell and warped a little, so I bought some new ones at the same time. Are your rims bent?

EDIT ****

The old rims and expensive tire were from the previous owner. I can't remember the name of the tires, but the tread looked the same. And I'm AWD, and stock suspension, and the damage looks the same! It might be a defect or bad combination of tires for a gsx. Depending if we had the same brand of tire.

NO.

Wear like that is caused by alignment, and alignment only.

As was stated before, it's caused by excessive toe, (positive or negative)

Get that ish fixed and you'll be good to go on your new tires.

Curious about tire pressure, clearly my door panel states 32 psi up front 29 psi in the rear. Is it supposed to be that high or is it what is recommended for your tire?

[crimsondragon]

Are you guys looking at it correctly? What I see is the tire being grinded. It looks like you been bottoming out and grinding that specific part of the tire away with the upper control arm I believe it is and that stud is tearing at the tire as seen by that uplifting.

The factory recommended tire pressure is on the low side primarily to provide a more comfortable ride (more flex in sidewall to help absorb bumps) as well as providing a bit more contact patch in the rear for better grip to help prevent oversteer which is harder to control for the average, non-skilled driver.

It's best to experiment with tire pressures to maximize performance since every car will respond differently. Higher inflation pressures (within reason) will make the car more responsive to steering inputs and will also give you better gas mileage but the ride will feel more harsh.

FWIW, through trial and error I've found that 34-36psi on all 4 gives me a good balance of handling and straight line traction. If I was AWD I would probably go a bit higher than that. For best accuracy check tire pressure in the morning before driving (before the tires have heated up).

Looking at the third pic I doubt that's the case. I don't see any evidence of rubbing on the upper portion of the steering knuckle (part that attaches to UCA). The tip of the UCA ball joint stud also doesn't show any signs that the tire has been rubbing against it.

[asian312]

This may not apply to street driving, but if your tracking your DSM, you want to know the 'hot' tire temps as opposed to 'cold' temps. Different tracks will heat each tire differently and getting them to the same operating pressures means leveling them out after a few flying laps. Also different tires will increase and/or decrease temps at different rates, so dialing in a setup is generally car specific. Also due to suspension, driving style, ect.

PS: The tire moves in relation to the inside knuckle and UCA. Therefore a change in position of the suspension does not relocate the tire from either components. About the only rubbing a tire will have will be on the inside sidewall from either improper clearance or flexing of the tire. Not sure if this has been mentioned, but what wheels are these mounted on. Curious if the size/offset has anything to do with this, but my hunch lies with everyone else with the alignment as the culprit.

Honestly, i was thinking the that it was being grinded away just because of the specific part of the tire that gone. IS it possible for the upper control arm could do this?

[kanderson]

NO, the position of the control arm in relation to the tire does not change when the suspension compresses, as stated above, so there is no way that it could have rubbed on the tire. Excessive toe will cause this symptom, as will negative camber (to a degree). An alignment and new tires are what is needed.

[Evan K.]

As stated above it's your alignment, specifically your toe setting. I run a lot of negative camber and don't wear out the inside of the tire because I have a proper toe setting.

[BoostedinSoFla]

Go get new tires and an alignment. Has nothing to do with your tires rubbing against you control arm.

[mavisky]

Looks like too much toe-out.

Odd wear though since those tire pressures are way too high if they're being taken cold.
