Tires wandering?

[Bandit]

Hey guys, I was wondering, is it normal with wider and stickier tires to get a feeling of the front end of the car wanting to "wander" due to irregularities in the road's surface?

I did not notice this so much with my old harder compound 225's, but now with my 245 Nitto's it seems I have to concentrate harder on keeping it going straight at high speeds (100+). I did have an alignment done as soon as I got the new tires installed, so I don't think that's a factor. Also, it doesn't seem to pull one way or the other.

I have a new steering box so there is very little play in the system, which is good, but I find that I need to make subtle steering corrections a lot.

Would more positive camber help to correct this?
