First, decide on which tire best fits your driving surfaces. As noted above, off-road capable tires can be noisy on highways, if that would be a concern for you. If you are predominantly a paved road driver, the Michelin Defenders are the way to go, in the opinion of many folks here.

Regarding fit and potential rubbing issues, compare any alternative tire to your current tires, using the tire size calculator link below. You will be able to plug in current critical clearances with fenders and suspension components for your current tires, and then model the changes to those clearances with any alternate tire.

I wish you the best of outcomes on your tire search and conversion.
