I have AT Italia S5 wheels and the cone seat bolts sent to me are about 2 threads too long (when I snug and torque them the hubs won't turn).

I had the seller send me a new set - but he sent same ones, still too long.

The OEM bolts are just the right length, but they are ball-seat type.

I am trying to find a proper length set of cone seats (or machine this set down a bit), but until then I have installed the wheels with the OEM ball seat bolts. And they wobble, even though I had the wheels trued and Roadforce Balanced. And I DO have hubcentric rings installed.

Could ball seat really cause balanced wheels/tires to wobbble? It really doesn't seem like they could be mounted off-center, but I'm not sure. Maybe I need to have the balancing checked again?

You could ruin the lug seating surface on the wheel and or/lugs. Also, since they won't torque properly, you could risk the lugs loosening while you drive.

Call Gary @ Tire Rack to get a proper set. He should have them, since they sell AT Italia wheels.

Called TR already - wouldn't sell me just bolts. Probably should've talked to Gary first...

call Gary directly...I've bought lugs from him in the past

Mr. Gary - Please advise, do AT Italia S5 require cone or ball seat? 18x7.5 ET20 for allroad. TIA!

Gary@Tirerack.com

At least the ones that we sell use ball seats.

Shoot me an email with the complete list of part #'s off of the back of the wheel and I'll double check.

Gary, when I called TR they told me they were cone seat?

sbmrinaldi

pitch, 30mm lenght, 17mm head, 54mm total lenght. Please advise if that is correct since that is what I bought.
