Can dex cool antifreeze be used to load tractor tires is dex cool antifreeze corrosive to tractor tire inner tubes?

It's not corrosive (consider: DexCool runs through radiator hoses. They're rubber and it doesn't eat them), but it is extremely toxic, and if your tire springs a leak the EPA will be on you like white on rice. I found out about a product called RimGuard, which is non-corrosive and very safe to use.
