I can see doing this. First, I like the look. Second, you are dropping somewhere in the neighborhood of 70 lbs, depending on tire and wheel combination, at little to no out of pocket cost. That can save you about $50 in gas a year on a daily driven vehicle.
I don’t DD my Jeep now but I probably will again soon. I commute 50 miles a day almost all in-city interstate. If I get a flat on a heavily trafficked 8 lane interstate, do you think I am kneeling on the narrow ass shoulder, filled with all kinds of debris, and changing the tire? Fuck no, I pay an extra 5 bucks a month to progressive to have roadside assistance, they can tow me to the nearest tire shop for repair.
If I am going wheeling, it’s not a surprise, I have plenty of advanced notice and I could take out my backseat and throw my spare in the back. I have also kicked around the idea of a removable mount I can bolt up just for wheeling trips but I am not at that stage of my build yet anyway.
Now before I get a bunch of pushback on trying to save gas in a TJ, let me say that’s not the reason I want to drop weight, but someone else might. If you look into how much gas Americans waste each year just by being fat, it’s pretty remarkable.
