Super six van

So I had to put the spare on from my grand caravan another and tire from my van also cause the van was to wide to fit on the trailer. So I was following my bro in law and since I took a tire from the b100 and put on my van to drive I got a flat tire. Never easy. Now we have to unload this damned thing when I get home and pull my tires back off and put back on my grand caravan.
Also looking at my 3 week old brand new tires the fronts are half way gone wtf. Spend 400+ for tires that won't last bit a few months. What am I supposed to do **** me running
