Bulletproof Tires?

Marketplace:

Adriene Hill: Genetically modified crops are engineered to be tough. It helps them fight off pests, withstand drought.  And it's a beefed-up-ness, you can see.

Mark Newhall: Their stalks are stiffer and tougher.

Mark Newhall is the editor of Farm Show magazine.

Newhall: So when you cut them off to harvest them, it's like having a field of little spears.

Little spears that are stabbing, and bumping and chewing up tractor tires -- poor tires.
Robert Parks is the owner of Custom Tire Cutting which customizes tractor tires. He says this GMO crop stubble is killing tires early.

Robert Parks: In some instances, just a year or two, where normally they would get five or six years out of the tires.

And, replacing them is no small thing. We're talking hundreds or thousands of dollars per tire and tractors with, sometimes, eight tires. Which means farmers, faced with these tougher stalks, want tougher tires.
Parks' company will harden tires for his customers by baking them. But the tire companies are on the job too. Jim Patrico is an editor at Progressive Farmer magazine.

Jim Patrico: They're doing things like a kevlar lining.

Yup, that kevlar, the kind soldiers have in their helmets and vests.

Boy, the anti-GMO folks were freaking out about this.  But, honestly, there are a lot of plants that are pretty tough already.  It is a sign of plant health that in high population areas the plants are able to maintain strong stalks.  The real trouble comes where the population is low, and the plants are able to grow bigger.  That's really bad news.
