So i managed to run over a groundhog hole while mowing. I now have a bubble in one of my front tires (which is practically new). I do alot of heavy lifting w/ FEL. I found a skidsteer tire for $65 that is an 8ply construction tire vs. the standard 4ply that comes with the tractor. BKT Skid Power HD Skid Steer Tire 18x8.50-10 (8 Ply) (TL) Is there any downside to using an 8ply tire? can i still run it with lower air pressure when mowing?
