No. Tires won't 'knock'. Loose wheels could but, more than likely, Some part of your car's suspension is not right or is giving you signs it is worn. ie A worn tie-rod end will 'knock' when you go over a pot hole or up onto or down a curb or ramp as with your driveway. Cars generally emit these sounds and you should heed this as a warning. Have this checked by someone who knows how.
Hi if you hear the knocking noise more when you go over slightly bumpy road then the chances are the bottom ball joint needs replacing these dont cost much to buy and its best to replace both sides, you will need some special tools such as ball joint splitter and a workshop manual would be helpful if you have never done this before and you are doing the work yourself
another problem could be the anti roll bar bushes what you can do to test to see if its the bottom ball joint or not is to jack the car up so that wheel is off the floor slightly then place a stand under the car so its safe to get under then get a strong bar such as crow bar and get someone to put this under the tyre and lever it up so they are lifting the wheel up and down slightly then if you get under neath and have a look behind the wheel then the bottom ball joint is the part that fits into the bottom of the hub, now once you have found this see if their is any play when the person is lifting the wheel up and down with the bar.
if their is play then it needs replacing, it will be hard to lift the wheel up and down so you will need a strong bar to put under the tyre on the road and wiggle it up and down so it lifts the wheel slightly then have a look and listen for any play in the bottom ball joint.
let me know if you need further assistance ok

It sounds like the CV joints are due to be replaced. Make sure you get them replaced and do not drive it too far, because the CV joints will fail anytime now. Once the CV joints fail, your going to have to get the car towed to get it fixed. Good luck and keep me posted, Oh and don't buy the car from there, who knows what else is wrong with the car that they are hiding from you.
Hi I am Vortash .. I have to say first that this is not a car I have ever worked on , but it's a car so the fundementals will still be the same . Steering shudder usually occours due to 4 things Road wheels or suspension or steering itself ( this includes the ball joints that you say you have replaced )
1/ when you have new tyres fitted it is usually par for the course that they are balanced , this is the wheel is spun mechanicaly and a machine measures the axis wobble or TRUE .. a metal weight is placed at a point indicated by the machine to equalise the weight and give a true spin.... These weights sometimes come off causing the wheel to shake .
The wheels are buckled pot holes cause severe camage if hit at speed also knocking the tracking out causing tyre exstensive tyre wear .
2/ The suspension uhits .. if they become damaged they themselves wobble transfering movement to the steering
3/ steering the track rod ends wear and become loose allowing the front wheels to again wobble and run out of true .
4/ wheel bearings worn severly
The popping you hear I suspect is the sound of the tyres being dragged one way or the other traping air and poping it out , but I would have thought to do this the tyre pressure would have to be extreemly low .. you should have a miniumum of 24psi in the front and 28psi in the rear which is increased at the by 10% if towing .
it could be a balljoint on the left side i cannot be a hundred percent sure without seeing the car but any tyre or suspension place should be able to tell you for free before any work is committed. then if your able fix it yourself. if not get them to or i can try to talk you through what to do
