These are an off road specific tire and not designed for use on pavement. The performance on pavement will suffer due to the large tread void with tall knobs and low contact patch. The performance on gravel will vary depending what you are comparing it to, but will be just fine to use on gravel. Some riders complain under hard cornering the sidewall tends to flex a lot and they get and they get a feeling of the tire rolling. This would also depend on how much pressure you are running. For all intents and purposes this is a very popular tire because it really works pretty good everywhere. About the only place it has downfalls will be on pavement which is not designed to be used on, and in the deep sticky mud as is does not have the deepest lugs or best cleaning ability.
