Falken 452 cupping

Falken 452 cupping
great tires but my front tires are cupping and it sound as though I have knobby tires!
I read that because the falken are built with block pattern the agressive type alignment of the XKR will cause that to happen.
Hoping Discount tire will exchange them or claim them under warranty.
Suspension is perfect, newly rebuilt, ALignment perfect
When I first purchased the tires they sounded so quiet, now after 8K they sound horrible.

I've had 2 sets of 452s on my TT, no problem and currently on the XK but not many miles yet and have not seen the problem. However your post triggered a memory of a discussion about this problem on a UK TT forum a few years ago which may be of interest.

Depends fellas,
Scalloping, cupping, feathering are the most common terms
Equally on both new tires
Recent rebuilt front end including shocks etc.
Like a DX aka differenetial diagnosis for a patient...gotta have all the information before narrowing down the culprit.
Bad shocks can cause cupping throughout the tire
But we have a known issue with the tire build and pattern, block patterns on the edge of a tire are the first weak spot.
Aggressive alignment specs on the XKR
Rubber compound
completely smooth ride
ZERO vibration or steering wheel vibrations

BTW I said it was a common term.
The issue has been cured Tires are on and no more road noise etc. Ill be taking a trip to Phoenix next week so Ill be ready to see if there are any other issues.
I have yet to see a real tire EXPERT at discount tire. However my son does work for them in phoenix at the head quarters. Judging by the number of returns and complaints on other more popular brand of vehicles the diagnosis is on the money. Falken recognizes the known problem

I've always associated tire "cupping" problems with the vehicle as opposed to tire problems. I could be wrong but I would focus on the vehicle no matter how perfect you now consider it to be.
Mind you, once tire cupping starts it's hard to stop even if you have cured the problem that initially started it.
