In my words
Reaction+ HP Wide SC S3 Drag BELTED Tires is the On-Road & Drag rubber I reach for when the track is dry packed dirt and grass that rewards a mid compound.
Rubber ages on the shelf as well as on the track, so I run sets rather than hoard them.
Sizes and colors come and go on this one; the listing shows what is actually in the box today.
What Pro-Line says about it
- Extra wide belt that wraps further into the corners of the tire to prevent any expansion
- The Reaction+ is about 20% wider than the original Reaction HP tire
- Made from Pro-Line’s soft S3 compound
Questions I get about this set
Do I need to glue these?
These are tires and wheels separately, so yes — bead glue is part of the job. Pro-Line tires want thin CA worked around the bead in quarters, not one bead of glue chased around the rim in a single pass.
Which insert goes in?
Inserts are not included with this listing, so budget for a set. A closed-cell insert holds shape under load; an open-cell one lets the carcass work. Heavy cars and high-bite tracks want the firmer option.
