The width difference will be negligeble on that frontend with 235s, they're anly mabe an inch or so wider. There's several advantages; 1, it looks better, 2, handling and braking will improve ue to the larger tire footprint, and probably the best reason, availability. The smaller sizes are going obsolete very fast, especially the 205-225 sizes in light truck tires.
Where the problems with the frontend come from is when a wider wheel is instaled, as they offset has to be further to the negative side to keep the backspacing the same. This can shift the wheel centerling to far out, putting axtra stress on the bearings and balljoints, plus it alters the scrub radius, which affects the alignment angles during turns. 235s won't be a problem on that frontend, as it was used as a factory fit on the virtually same suspension on the later trucks.
