No problem at all.

I know what you mean. Nothing but bad breaks.
The reason I asked is that I use AGs and have had only a few punctures - mostly from pointed stobs from 1.5 to 2" dia stumps left by beaver.

You dont plug those! In only one case have I gotten punched by small wood. In that case, like yours it was a seasoned pungi from a prior cutting. All in all Im pretty impressed with the puncture resistance. It surprised me that an R4 carcass would be vulnerable to small wood.
... One thing Ive noticed is that new tires cut and punch more easily. I think the rubber is soft for quite awhile and a middle aged tire is probably at its very best for resisting penetration. Its tougher all the way through. Im betting those R4s are kinda young ? Theyll be stronger in a few years if they dont get perforated too much before then.
