Looking for opinions on tires for 99 Wrangler

Currently considering 3 brands

Dunlop Radial Rover A/T (seen mixed reviews for wear on tiretrack.com)

Michelin XC LT4 (made by Michelin for Sears, think is may be similar to M/S
series?)

Multi-Mile Tires. Am going to look at today.

Tire size is 215/75-15. Was also suggested by one dealer of putting
235/75-15 on the 215 rim. Is this ok? Was suggested for wider footprint
for better traction, and warranty (road haz, etc that comes w/tire).
Jeep is use mainly on road use. Any off road would be dirt/gravel roads
w/occasional trip across dirt fields for dove hunting.
