Since new and old compound tires will co-exist during this transition period, Maxxis has new nomenclature to distinguish the new product from the old.
- The new compound developed for the RC-1 is called “R2” and the old compound is called the “R1”.
- The new compound developed for the VR-1 is called “S2” and the old compound is called the “S1”.
Future product descriptions will include the compound designation to minimize confusion. For example:
- TP00058700 255/40ZR17 94W RC-1 (R2)
- TP00000700 215/40ZR16 86W XL VR-1 (S2)
The R2 and S2 compounds are slightly different since the VR-1 was designed for more on-road use in dry and wet conditions. Both compounds are not designed to be used below 32ºF (0ºC) so please see our technical bulletin on cold weather storage guidelines here: https://www.maxxis.com/cold-weather-storage
- Performance improvements:
The new R2/S2 compound improved tire irregular wear on track, handling, and overall grip. Maxxis recommends using the same compound tires in all positions.
Customers can distinguish the old/new compound by the following methods:
- New Part Numbers – Updated compound tires have new part numbers.
- DOT (Department of Transportation) code – The R1/S1 compound tires will show “ABC” while the R2/S2 compound tires will read ACC or ACL (see below for instructions)
Figure 1a and 1b: Find the “DOT” side of the tire by locating the red and yellow markers.
