When I start are slowing up are braking slow I hear a womp sound and a little wobble coming from the right tire,but the tire has pretty good treads.

 

Have the balance and tire pressure checked?
Is the rim damaged?

Everything Telcoman said, also when the tire is off inspect brake pads and rotors, might be a warped rotor causing the shudder. It's the middle of summer though and this is typically when tires give out due to age.

 

And check the date codes on the tires. If over 5 years old, replace them.

Out of balance tires don't make much of a noise, nor do warped rotors you feel both in the steering wheel! What do you tires look like, are the insides extremely worn? Drop by your local independent brake/alignment shop, they'll know what to look for in an instant! I'd sooner think it might be wheel bearing, they make noise and cause what you describe!
