Actual blow out? Or tire wear? 150hrs between changes are not uncommon for the nose gear RVs. Depends on how heavy footed the pilot is on landing.
Remember the brakes are used for steering, so will wear out faster than some other models of A/C.
Regular changing of the nose tire is good practice, insurance.
It's a good idea to change out the o-rings in the calipers every 500hrs or so to avoid any brake contamination, or worse, issues later.
One very easy test for wheel alignment issues is to pull the plane around, both forwards & backwards, if it rolls easily in both directions, it is pretty much built straight. If you do this on a nice epoxy hangar floor, you'll get a real squeal if things aren't in line. This will also be an indicator for proper wheel bearing preload.
