2010 lexus has 6,000 miles on front tires. Started getting a thumping sound that begins at low speed and continues up to high speed and never goes away. I suspected a broken belt or rotors. Took to Lexus and first they said mis-matched no name brand tires should be switched to match rear tires. I said was there anything wrong with the tires and they said they probably were just poor quality. I said that wasn't a good enough reason to buy new tires. Told them to check rotors and the inside of tires for broken belt. Now they say the tire has a flat spot. I'm not so sure these guys no anything but I do not have much to go on other than the noise and milage on the tires. They are Delinte Thunder. The rear are Goodrich tires. Any suggestions?

What you describe is a tyre problem, probably as you say belt separation
I would stay away from rotors at this point as they really will not give what you describe
you can try doing a tyre rotation and see if the problem goes from front to back
If it does then you will know that you need 2 new tyres
You can go to a tyre shop and have each wheel checked for a problem tyre on the balancer unit
if there is a case problem , it will not be able to be balanced easily
It is poor practice to run different brands of tyres as each tyre has its own handling characteristics and that will give you noise and control problems

SOURCE: squeak sound in the front right tire & a thump noise in the rear.

It sounds like you have a bad strut, have the strut replaced, if it does not fix the problem seek help from a suspention shop.

SOURCE: Grumbling Noise

yes it could cause the noise also having 80% tread is not good on the transfer case as it will constantly be putting stress on it. replace your fronts with matching tires and the noise should go away

SOURCE: Loud "tire or wheel" roar on the highway

I certainly would take it back to the shop that performed the brake job and have them investigate. If it was not making the noise prior to the repair there is a good chance the noise is involved with the brakes. A possible loose brake pad, a sticking caliper(caliper pins may need to be lubed) or any number of things could be wrong.

SOURCE: My front end makes a loud humming noise.

Alignment will not create a sound by it's self. The most common cause of humming (especially if you have an agressive tread design)is a wear pattern in the tires...check for that or rotate the tires around & see if the noise changes. If it does then you know it's in the tires. & Not always, but most of the time a bearing noise will increase or decrease in intensity if you load up one side at a time by doing 35-50 mph & turning slightly to each side.

SOURCE: front end noise sounds like a flat spot on tire

Sometimes the rotors rust just where the brake pads set. It happens a little more when the Caliper pins start hanging up. The pads do not get an air gap clearance when the Caliper pins stick and the pads rust to the rotor. The noise will go away as the brakes are used and the rust wears off. It will happen again when the conditions are right. You should see like a blotch of rust on the rotor depending on how your rims are made.

Another possibility can be a Constant Velocity shaft boot/shaft making noise. This would best be checked on a hoist. It may take spinning the shafts while the car is in gear on the hoist.

The last choice would be a scuff sound caused by a bad hub bearing.

What could cause a thumping noise from the front end when turning at low speed?

sounds like wheel bearings-1st
but hopefully your front disc need turning, or replaced.
check wheel bearings by jacking up the front end "CAREFULLY" WITH
JACK STANDS & wiggle tires,if you get more than a 1/4'' slack on 1 or the other, than it's shot. Best to replace both sides. "GOOD LUCK'' &
BE CAREFULL.
