They kind of are like heavy equipment tires. I wonder if they come in any other sizes or widths. It would nice to get a set of tires that are hard to puncture. Right now, my tracker has this set of tire on it that are supposedly snow tires, but spin like they were bald in the snow(even though their tread is almost full), and I have a nail in the front right tire(it has a slow leak) and a staple or wire in the right rear tire(it would go flat within the day). I finally had to replace the rear one with the spare, which is a 190/75r15, while the others are a 215/75r15. At least these tires came with the car when I bought it. When I replace the tires, I will probably get some yokohama geolander A/Ts or M/Ts in 235/75R/15s(if they make that size).
