Best tires.... 7.50R16s
After 33s. 35, I'm now on super skinny 31s. 7.50R16s, a rire size going back to the 1960s and the most populat tire size in Africa or Asia.
The week I bought them I hooked up the trailer and did a 500 mile trip thru the mountains. The year before I averaged 14mpg on 33x10.50R15s. This year I averaged 17mpg towing a trailer. Without a trailer my best was 17mpg, without the trailer now my best is 22mpg.
Best thing I did was buy skinny, light 7.50R16 rubber, increasing my range by 100 miles. A huge difference overlanding. And it is easier to get 22mpg now than it was to get 17mpg before.
My Square Drop Trailer is all about convenience.
The TJR over say an F150 is all about compact, manuverable capability.
But the tires are purely about performance and increased range, Smoother ride a a 50% cost saving are bonuses.
In 2 years, 50K miles, I don't feel I lost a bit of capability stepping down in tire size. Actually in winter thru slush and standing water I made incredible gains.
I can cross the centerline, pass a Dodge diesel, come back thru the slush, while he is white knuckled trying to stay in the ruts.
