Towing with a Toyota Sequoia: wheel size question

[Krisbabs]

We recently bought a used 2010 Sequoia Limited to tow a travel trailer. (It's rated to haul up to 7500 lbs., we're just looking to tow 5000 or under. We haven't pulled the trigger on one yet, but we've towed a couple rental trailers and it's done pretty well.) The Sequoia is about due for new tires, and it has 20" wheels. My brother recommended that I get smaller diameter wheels for towing. Any advice for a towing newbie before we drop extra $ on wheels AND tires?

The diameter of the wheels doesn't matter
The diameter of the tires does.
Having said that, shorter tires than stock will give you more pulling power. It has the same effect as changing gear ratios. The downside is that the speedometer will no longer be accurate, and you will lose some ground clearance. A gear swap may actually be cheaper than new tires/rims.

Your money, your choice
