Time to buy some tires

Question: does a bigger tire offer so much advantage that it's worth the extra cost?
I'm tempted to put stock rims and tires on this bad boy, but I do want to do some offroading. Realistically, I will be doing lots of hwy with *some offroad.

I'm open to changing the rims. Would a newer rim size make for a better tire selection?

I had a tire disintegrate on the highway today, it motivated me to buy some new tires! It did not blow, but it threw some rubber and SURE woke me up!

Since we all love pics, here you go:



Here is what is currently on it some very old:
BF Goodrich All Terrain AT 33" x 15 12.5



They are pretty age-cracked so they need to go.
BUT Replacing them is about $1000. And I'm not sure I like the super wide tires.

I always liked the look of Stock 3/4 ton burbs, but I plan on doing long trips with some offroad. So not sure what to get.

Here is a "stock" size 31" x 10.5 (my Spare)




Vs the bigger ones:



What tires did you like and why?
I'm trying to work on a budget here...!
