But they do grow. My 30” radials will grow another 1” or so in height on the top end.
To the OP, don’t know what you are running but if you have something that’s not a crazy high horsepower machine, you won’t have problems. My slicks have rubbed but it’s usually when I’m turning hard with speed. I make sure that all edges are not sharp around the wheel well and there’s no way for the tire to “catch” on any metal resulting in a blown tire. There’s a lot of guys here and everywhere running mini tubs and slicks. I haven’t personally seen any disasters resulting from the tires rubbing. I can barely get fingers in between the tires on mine and haven’t seen any problems yet.
