I have a 95 f150 xlt extended cab 4 wheel drive and I put on bigger tires today and now front end is shaking a little really feel it in the steering wheel do I need an alignment?

 

Could just be the tires.
Also bigger tires will stress the steering system a little more, so any weak links are more likely to show up.
Jack up the front wheels and see if you can move them - back and front, top and bottom. If anything moves around without the thing that it's attached to moving the same, that's a problem.
If in doubt, take it to a mechanic and give him $20 or $30 to check out your front end. Cheaper than a ditch.

 

I ended up having a bent rim so wouldn't balance right searching for some now I switched it to back now smoth ride.
