TruPower is where your money is best spent.
I had SuperLugs on my now sold 1872, in gravel they were usless. The lug bars are so far apart that the area between the lugs would bulg out to nearly the height of the bar thus in gravel the bars did not dig in.
You won't need to swap out tires for mowing if you use TruPowers, they are great for mowing. They don't have good traction of backing up hill though when the grass is wet.
Tires that are soft have 'tack', as they age they become hard and lose 'tack' thus they lose traction.
I get dismissed here for bringing this up but if you ever dipped into a turn at 80-90 MPH you will appreciate 'tack'. I would never ride on motorcycle on tire more than 3 years old.
I have a few limestone rocks that are just below the surface on my property, on my hills. A 30 year old tire will just sit and spin on that rock, the tire is hard and slick, a newer softer tire, as I have on my tractors, will and do simply ride up on the rock and do not slip. Same for damp grass, an old hard tire is more likely to sit and spin.
But hey!....
