Bad Cupping on Tire

too much burning rubber! I would show the dealership the cupping tire and ask them to check the alignment, if the alignment is off it could be the tie rod end or just be out of alignment. Good luck!

I don't suppose they would do that under warranty or out of the kindness of their hearts.

i'm guessing if it's still under warranty then u should have it fixed under warranty. they may not put tires on it but if the alignment is out that should be covered. I would show them the cupped tire and assure them u have rotated the tires.

If when they were rotated, they did it from Right front to right rear, It was done wrong

My dealer did that, the Owners Manual reads that it is to done in the X pattern

UNLESS the tires have the ARROW pointing the direction of travel

My right side tires kept cupping, I have since changed wheels & tires, waiting to see if there is any sign of unusual wear

I believe alignment warranty is 12/12000 unless work on front end parts then maybe.

This is correct. Alignemnt is a 12/12000 mile claim.. I have cupping issues on my 20's as well..

Started @ about 28k.. The noise is staring to drive me nuts..I have 20's on the last 4 Dodges and this is the first time for cupping..

Just a word of cauation, tell the dealer you have problems other than allignment. That is not a waranty issue. Tell them the symptom not to do an allignment. As far as the cupping had that same issue on my 2008 Ram with two sets of Goodyears, when I switched to Michelin that issue went away.

Cupping has a lot to do with a lot of factors... Shocks, TREs, ball joints, alignment, toe, you name it. In the end a LOT of new vehicles cup the outsides of the front tires. My take is that they put a little positive camber on the wheels and they look like this:\ / That combined with too much toe and the outer edges occilate.

My guess is they setup the truck that way anticipating some loading which will square up the patch to the road.

I'd show the dealer the wear and see what adjustments they can make to neutral the camber.

I have the same issue with my 20's. I've had the dealer realign the truck around 8k mi. They were no help other than that. I'm fairly sure it's due to the crappiness of the stock goodyears. There are many, many others experiencing this. Per the suggestion of another member, I raised the air pressure to 45 psi and it seems to have helped somewhat. Once they wear out, I'll swap them out for some nittos or coopers.

I have slight feathering. Rotate tires about every 6k. Just rotated tires today, found left TRE worn. 22.5k miles. Need to call the dealer.

when my badyears started to cup and vibrate it happened really quick. like within 2-3k km's. dealer was absolutely no help. discount tire did a check when I had the nitto's put on and said the front end was fine. just another case of tires designed by accountants.

If you have the good for one year tires that is the problem, junked mine at 2000, already a bumpy ride and cupped tires, Bridgestones no more problems, had to do the same thing on my 300 SRT.

same patten with mine Ram dumped the goodyears at 12k went to a Michelin LTX and whoa got a new truck again at 12k... freakin best tire for your Ram.

I would dump mine but I shutter at the thought of buying new 20's without getting milage out of the ones that are on the truck. I was on the fence about getting that particular truck because of the replacement cost of 20" tires. But being the savvy financial analyst that I am...I did it anyway.

20s have become the standard in SUVs and LTs and are insignificantly more expensive than a 17, frankly. There are plenty of reasonable options in a P-metric that are perfect for our trucks.

Thanks for this thread! I wasn't sure what the heck was going on with my truck. Seems ever since I had that tie rod recall done and tires rotated during same visit my truck hasn't driven straight since. Had to PAY for a full alignment, tire balance, and tires rotated back to where they were at a local tire place because I wasn't sure what the heck was going on. Seems to be driving a little straighter since I've had the tires rotated back. All this aggravation because Dodge can't put decent sneakers on a 40k dollar truck??? Give me friggin' break!

I think anyone who had these tires should be compensated.

I had the very same issues with my goodyears - feathering on the outside edges - very bad. I had multiple alignments done, rotated them religiously, etc, and to no avail.

I ended up swapping out the stock goodyears at 36k miles for a set of cooper zeons and haven't had a single issue since.

I really do attribute it to the poor quality of the tires.

I am of the belief that the truck has insufficient damping. I'm going to try a set of the bilstein 4100s and prove the theory out. I noticed the damping issue after changing from the lighter 17s to 20s.
