Changing drive tires, which ones and how many?

X line energy D are great and in bad weather all the sipes help with grip. They are long wearing. Generally get 400k out of a set or about that.
Can’t go wrong

 

Get another 4 months out of them.

 

In reality, in the winter, 6/10 isn't where you want to be. Run them till the end of October depending on where your at. Maybe change them out sooner. Get the allingment at a shop that does a lot of allingments. No point spending 4k to get them fuked in 2 months. Change shocks too, 6. They should be around 50 a piece. You can do it yourself. I broke them with a harbor freight breaker bar with my flat bad bar sliding over the end of it. Then put back on with a little grease to stop rusting.

Good luck.

 

As to jr I in

 

my rule of thumb has always been new set of shocks every 100k all around including cab shocks. Do yourself a favor and use anti seize on the bolts. Not sure where you are from or location but MD alignment has various vendors around the US that do alignments. They are good alignments as well. Just my 2 cents

 

BTW T/A Petro is not the place to go except in an emergency for anything except fuel. Rip off artists and don’t trust the shops. Again just my 2 cents

 

Midnight, you didn't say t/a did you?

Seriously never go to t/a.

Never ...

I will let others tell you where to go to get a good alignment, I have a mechanic that does that.

It is great you have consistent wear, that's very good.

Yes replace the shocks, don't go fancy, Oem shocks if they served you well, use them, buy them now, look for a discount and then you won't get the mark up.

Oh and get oil and fluid analysis on your trans and axles.
