x2 it might take you awile to mount them urself but once your all done use the money and buy u some supper at a steak house for all your hard work lmao, you will feel better, then every time you look at your big ole tires youll think, omg i did it myself, thats how we mount all our tires, including the 22.5s on the semi of my dads, did all 14 one day, have the big wide single on the rear of the truck=pita lol, tip= throw some golf balls in em to help with balance on those big tires, it helps
not dawgin ya dude but but try some dawn dish soap, it will last longer than the windex because im sure it will take you awhile and lube the wheel up before you attempt to put the tire on, it helps
please dont take that to offense obijuan, may the force be with you
