I’ve only had it up to 45 mph since im waiting on a sticker to hit the open road, but its extremely stable on the road and on sharp turns. I regrooved the swampers so it is bumpy, not to mention they are not balanced. A new set of tires would be much better at high speeds. I spent way too much money on tires last year between my RV, truck and trailer so I am milking the Swampers a few months.
