I use the same thing, just inherited the reamer and plug tool from my pop years ago. Typically they last a long time inflow speed applications and I can't honestly say I've had an issue with them in an "emergency" situation, on the road. If nothing else they get you back to the shop to do a proper patch/patch plug. Wouldn't worry about it in a tractor.There is no need to remove the tire from the wheel. .. these are low speed off road tires. Use a standard string repair, available with tools and glue for $10 or so. About 2 years ago I stuffed about six or eight 8” into my RR R-4 crown area when I picked up a pin from a sliding barn door roller. Still holding, calcium filled. View attachment 82430
