Nitto Invo & Dinan Springs/Alignment (12k Miles)

Folks,

I'm hoping someone can help me figure out what caused this. I run the following:

19x8.5 et45s 225/35 (F) 255/30 (R) on Dinan Springs and BumpStops. Forcefully did the alignment the day I had the springs installed.

I recently took my wheels to get powder coated and I received a call stating that all of my tires were shot (12k miles on them never raced).

Take a look at the pics and please help me understand what the Dinan alignment causes (based on the specs) my tires speak for themselves.

not happy

Thanks for the reply.. can you tell that from the specs I posted or are you going by the pictures?

which tire is which?

the 4th tire picture looks better than the rest... is that the front?
and where is your alignment sheet after alignment?

2nd (rr) and 3rd (rl) pics are the rears the worn is on the inside. On other pics are the fronts 4th(fr) ,5th(fl) and 6th(fl) again the worn is on the inside.

Alignment was done based on the specs i posted they were not able to pull up a copy the receipt.


Thanks for your feedback

Well unless you have the alignment sheet you will never know if they were "done based on the specs".... not that it matters much at this point anyway...

it's really weird that the one on the 4th has so much more thread than the rest...

Also the rear don't look worn unevenly either... maybe too many burnouts ?

What you can do after you put new tires is take it to an alignment shop (preferably not the same that did the last one ;-) ) and ask them to check your alignment, so they will put the sensors on the wheel and read what's the current numbers... if they are off then you can ask them to align it

Maybe its the pics... i had 2 different shops inspect the tires and not know how to react to them. The tire mesh showing and splitting on the inside corner of the tire is not from burnouts. But thanks for the info.

ya that looks like something cut through the tire like a sharp curb or something... else you would have the same thing all around the tire

Its on both rears... I spoke to Dinan (cool dudes) they are going to assist with trying to figure out what the deal is.

I'd get printouts of your current alignment. My guess your toe is off. Those camber specs are nowhere near the point of having to worry about tire wear. I've run almost 3 degrees of negative camber and 0 toe on a number of cars and the tires wear perfect. Your toe settings will most certainly cause issues though if it's not right.

seems like your alignment was off, but 12k out of a tire with a 260 tread wear is quite a bit under any conditions I could think of. Also looks like some of those tires were overinflated and a 225 on a 8.5 rim might be a little stretched, causing the tire to heat up and work a lot harder.

Is that the specs they recommend after lowering your car on Dinan Springs?

The first thing that comes to my mind is toe in. Usually, outside wearing out faster than the inside means too much toe in, inside wearing faster means the opposite, too much toe out. Anyway, that would mean out of spec or too much away from the median value they offer in the spec sheet.

I don't think with just the springs you can get nearly enough negative camber to produce the inner side wear.

Having your current toe in and camber numbers would certainly help understand the issue better.

Make sure the tires are the right pressures.

Last but not least, check your suspension bushings to make sure they're not shot since sometimes even with static toe in and camber within the spec but with comprimised bushings that go way out of spec while driving you can get something similar to your situation.

I don't think that kind of wear has anything to do with your tire of choice.

It sure looks to me like two things occured:

1) The aftermarket wheel offset caused the tires to contact points of the suspension under certain loads.

2) The suspension settled a bit after the alignment and causes a toe problem.


Stretching the tires certainly didn't help either.


Old thread, I know.

This. Alignment can go out of whack at any time, and new springs settle, which can cause alignment to go out of spec. If the OP didn't have it re-checked a few weeks after after having the wheels and springs installed, this is on him, IMHO.

Anything other than OEM specs -- even something as small as a few millimeters of offset, caused by a new wheel, spacers, shorter springs, etc. -- will require a different alignment spec. Even a small difference in rolling circumference and contact patch profile -- like, say, a Plus 1 conversion to 19"s, combined with a stretched sidewall profile (either convex or concave) -- can make a difference in the geometry of the suspension.
