"I hope to install the widest tires I can fit on the front and then use the same on the rear."
Remember TODD M that you have to steer this thing and those wide tires up front make that more difficult. Mine has 235R15-70 and it is too much tire. Paralell parking becomes a challenge. The wife can only do straight line driving and it's her truck. I'd recommend a 195 or 215 as the largest front tire w/o PS.
