Noticed that right rear tire has a small screw in the tread and its does show some bubbling when water is poured on it. Anything special I should know prior to having the tire changed? I am going to replace with new even though it only has 600 miles on it. The tire store, Discount Tire, says they have done the GT before and have the jack pads. FYI, total cost including balancing is about $400. thanks.

Make sure they do the high speed balancing (I don't think all of them have the equipment for that) - regular they do is probably not going to be sufficient.

Thanks AZGT! You wouldn't happen to know the torque numbers for the lugs would you?

Go to a place that has a Hunter 9700 road force balancer. This is currently the best system as far as I know. It will match balance the tire with the wheel. It will also indicate if tire or wheel is out of the usable range. A good tech that knows how to use this equipment is also important.

The lug torque is actually 111 as stated in the Service manual. I know, I know, the owner's manual says 100.

So which is correct? 111 lb. ft. is pretty dog gone tight!

Service Manual was published after the owner's manuals, so I follow it. AnalogDesigner agrees and posts those values on the card furnished with the jack pads.

My service manager told me 98lbs but the tire store looked it up and they had 110. I had them set 105. thanks for the reply's. Tire is on and I am rolling again only slightly lighter by about $400.

111, 100 does not really matter, as long as they are torqued evenly. 111 MIGHT not loosen sooner, but 100 will put less stress (lower odds of warping anything) on the assembly. If you check it occasionally, 100 will be fine...

Torque 'em at 100 ft. lbs.

The GT Guy told me 100 ft. lbs. is the correct torque to use [there are many errors in the Owners Manual and the Shop Manual].

And yes, TORQUED EVENLY is a MUST.

Yeah, yeah, the GT engineers didn't even know the size of the lugs. 111 doesn't feel bad.
