MAXXIS VICTRA VR-1 AND RC-1 COMPOUND CHANGE
In response to customer feedback, Maxxis engineers have updated the tread compound on our Victra VR-1 and RC-1 to improve dry performance in the summer. This bulletin aims to help our customers understand the new nomenclature, performance improvements and how to distinguish the different compound tires.
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.
Figure 2a and 2b: Locate the DOT code area
Figure 3a and 3b: Read the code in front of the 4 digit date code.
