The biggest problem I see is to make sure you have enough clearance between your duals when going to a wider tire. The manufacturer's tire tables will tell you the minimum spacing. Not enough clearance and the duals will "kiss" as you drive down the road. If that happens, your tires will definitely overheat.

The manufacturer's tire table should also give you the rolling circumference of each tire so you will know how much your odometer will be off. Your odometer will read low because a wider tire of the same aspect ratio will be a larger diameter and will therefore have fewer revolutions per mile.

Other than the above, you will also need to be sure the front tires have enough clearance when your steering wheel is fully turned both directions.

The wider tire is also taller, so the revs/mile are different. That affects the speedo and odometer a bit. And do check the dual spacing as well - the wider tires could touch each other and that is very bad.

paz gave good advice.
