Had a set of wheels sand blasted. This revealed just how rough the insides that were covered by tires had become. I sanded the sharpest of the pits to reduce the apparent abrasiveness and sprayed a heavy coat of primer. The worst wheel got a skim coat of filler. The pits seem rather shallow, not to affect the strength, but are quite rough. I got rubber liners but they are a bit too narrow to completely protect the tubes. How severely is my safety affected?
