Weird steering "pulse" or tug to the right

So this just started happening - jumped in the Pathy and started driving, and the steering wheel wants to be slightly turned to the right. When I straighten the steering wheel, it pulses, or jumps a bit, to the right, and puts the wheel back to a slight right turn. The truck of course then veers right.

So, it seems like an alignment issue at least in part, but I can't figure out what is causing the pulse. When I straighten the steering wheel out, it seems to jump twice per tire rotation with the slight tug, until it "settles" into being slightly off center to the right and the truck then goes right. Its definitely tied to speed too - go faster and the pulse/tug increases in frequency.

Front tire pressure is good, and I don't see any obvious signs of tire damage. Any ideas what I should be looking for?

Check for play in the wheel bearings, tie rods and ball joints. If that looks good, as does the tires, have the wheel alignment performed. A "good" alignment shop will check those items prior to doing the alignment.

Well I got the front wheels off this weekend and poked around. The driver's tire actually has a slight bulge in the tread - looks like belt damage to me. The tires are near end of life, so I guess I'll order some new tires and TPMS, since that is another project on my list.

I'm not sure if this is normal, but it seems the previous owner replaced the OEM spare with a full size 5th tire that matches what's on the truck now, so I was happy about that.

Thanks for the reply!

I get Dorman TPMS sensors from Rockauto.com. They run about $45 each and have a lifetime warranty.

About your spare tire, it depends on the model. I have an 08 LE v8 and had a matching spare. I say had as the first time I put tires on the pathfinder I swapped out rims.

My 06 LE has a full-size spare with matching alloy wheel. My friend's 08 SE has a full-size spare, but has a steel wheel rather than a matching alloy wheel.
