My front tire (original) has almost 19,000 on it and feels really weird in corners so when they do the rotors on mine under warranty I'm going to have a new tire put on. They said the brake pads looked good.

19,000 miles on a front tire wholey ****. i learned a long time ago. when u change the rear tire change the front also. i did it the 1st time at the recommendation of the shop doin the work. wow whadda diff when both tires r new. cost a lil more yes but the feel of the road and my life r much much better. believe change both at the same time.

I've always rode the front tire till it needs changing. Heck got almost 5000 more miles out of it. The tread still has 3 thousands on it so its not worn out. But when they get to feeling squirrelly I change them out.

Standard Motorcycle Rotors
Normal motorcycle rotors are bolted directly to the wheel. While this works, it also prevents the rotor from expanding and contracting properly as it heats up from the application of the brakes. If the brake rotor gets hot enough, it will eventually warp, requiring its replacement. Most cheaper motorcycles, as well as cruisers, still utilize conventional rotors.

Floating Rotors
In order to reduce the tendency of rotors to warp and allow them to expand and contract without warping as they heat and cool, engineers developed floating rotors. Rather than being bolted directly to the wheel, floating rotors are bolted to a rotor carrier; the carrier is then bolted to the wheel. There are full floating rotors and floating rotors. Floating rotors are riveted solidly to the carrier, whereas full float rotors are bolted to the carrier, with a small amount of play between the rotor and the carrier. Full floating rotors can resist warping very well, since they are free to move as the metal expands. However, full floating rotors tend to a rattle a bit, due to the added clearance. Almost all high-performance motorcycles use some type of floating rotor.

i read this and went n lqqk at the replacement rotors on my 12 flhtc. the rotors r bolted to the wheel hub but where the pads grab between there n the hub there is a rivet in one of rotor spoke from your description looks like some kind of floating thing to allow for the expansion. again this is stock could it be some sort of floater rotor?
