^ Can't say for sure.
But from what I've been seeing, anyone who is for plugging mc tires, will plug a radial or a bias ply. And anyone who is against plugging, wont plug a radial or a bias ply .
Nope! My radial car tires always get a plug! About a month ago I got a flat on my car tire. Tried to plug it but it never held. Took it to the dealer and he scrapped it. Said it couldn't be plugged as the nail cut through the belts. Luckily, I DO have the tire plan and got a brand new tires for free! :grin2: (Not really "free" as I paid the extra for the tire plan.)
