4x4 are wide tires better?

A couple of pluses are they look cool and possibly better off road performance. On the negative side
must slower steering and they may be noisier at highway speed depending on the tread design.
I drove a customers Jeep Wrangler with huge tires on it and I swear I thought I was like taking off in a DC-3 the noise and vibration was unbearable. You possibly might find some front end shimmy or shake even with speed balancing and thus requiring having to install a steering damper. Tire wear may be uneven for some reason large tires can wear funny. You might experience wheel hop on tight turns.They can put an extra load on wheel bearings and steering components. Some of these wheels and tires are heavy. The ride may change some and you may or may not like it.
If the tires extend out past the body line be ready for some extra cleaning of dirt sand rain snow mud all over the sides of the exterior. I work on cars and trucks for a living and I have driven all makes with large tires and I honestly don't like them for reasons mentioned.

I have owned driven 4x4's for 25 years with many different size wheels and tires i have 3 different sets of wheels and tires now , I like the looks of bigger wider tires and the increase
in handling performance if you don't go to tall with the tires, the bigger wider tires will decrease
gas mileage while driving around town and increase it on the road, if they extend out side your wheel well ( the aggresive look ) they will sling road film / mud on your truck and on lighter trucks it is harder to get big tires balanced but if you use a good tire you shouldnt have a problem , personally I think the wider bigger tire sure improve the appearance of a 4x4 , in my openion and experience , i would say go for , you will love it
