Tire pressure is set at 38

No.. I am NOT lowered. It is the stock sport suspension package. The wheels are 19x10.5 and the tires are 275/35/19 so yea they are wider than stock... I will go have an alignment done and see if that fixes my problem.

Thanks for all the help and the responses!

 

I had same problem on an 05 sedan I just bought. teh tires looked fine from outside, and only noticed the inside shoulder was bald when changing the oil. I replaced the tires and had an alignment. They told me that the toe was off, adn that they fixed it. I know nothing about alignment issues, so I just said "uh, ok." So it is nice to hear that this could be a toe problem.

 

I have/had the same problem. I bought my g35 about 1 month ago and have put 20inch rims on it since. About 2 days after I bought my G, I changed the brake pads and when I took off the front wheels I got a nice surprise...inside of the wheels were worn and metal was starting to show through the rubber.
I put my 20's on it about 1 week later and still have them on. My G is on stock sport suspension.

1)should I go ahead and get an alignment?
2)If I do get an alignment with the 20s on, will I have to get another alignment once I put the stock wheels back on?(with new front tires of course)

Thanks in advance for any answers.

 

you need to run the air pressure around 35, also it looks like your toe is off which would cause it to feather i have a .5 inch drop an my camber is at -1.6 and .11 toe so it can be fixed

 

I would say alignment also

Try this tires. They should help the issue.

1)I would recommend an alignment when putting 20s on the car.
2) I would get it realligned once the stocks are back on (to the factory alignment settings)

 

So does that mean that every time I go from stock to 20's, I have to do an alignment? I live in Kansas City so I basicall have the stocks on from November to late February/early March due to snow/salt in roads. Getting an alignment every time I switch sounds a bit much but I'll do it if I have to.

Am I understanding it right? Alignment every time I switch from stock to 20s?

 

I recently had a problem with front tires cupping. The car is on stock suspension and stock 19"s. I had an alignment done and set the toe lower, however, I have been told that it should be set higher also. It seems there is more validation to set the toe higher than lower, but should this be done all around or just in the front? All the tires wore faster on the outside so I am also now running -1.5 degrees of camber on these new tires to try to even out the tire wear.

 

It will affect the alignment to some extent. IMHO, a bit part of your problem is not having an alignment for so many miles. These cars are very fussy about having the right specs or you'll experience tires issues.

 

As in higher toe, I'm guessing you mean more positive toe/toe in? Toe in for the front is good for high speed stability but bad for turning. If you adjust the toe, I suggest you change only the front, and leave the rear alone. Too much toe in or toe out will give you a lot of bump steer, and with too much adjustment in the rear, your rear wheel drive car will just feel really... unsettling. Just remember that when you step on the gas, your front wheels will point out and your rear wheels or drive wheels will point in. Also keep in mind that excessive toe will negatively affect how your car handles in the wet.

And for the camber and tire wear, if you like the way the car handles before, you can just flip the tires (not just a wheel rotation) to even out the wear. And if your camber is fine but you're getting irregular tire wear, then check your toe.

 

Yeah I was talking about positive toe. Right now the toe it set at .05 all around, but as I said, I heard higher would be better for cupping - something around .25-.27 (highest in the specified range). So, going off what you said, I would change the fronts, to a higher positive amount of toe, and I'll let the rear...?

 

I can't answer that. I left my rear toe at a very conservative factory setting because I did not like the bump steer with almost one degree positive toe after I dropped my car.

 

Do sedans have the same tire wear issues as the coupes?

 

Wow @ the OP...wow...
