Team Losi Tire Guide for Off Road and On Road

[Plex]

Although it is impossible to classify every track type and surface, the following guide can be used to give you some direction and help in tire selection. Most tracks have either hard or soft surfaces and one or more of the various conditions noted.

Hard Slick: surface packs but does not take rubber.

Abrasive: natural abrasion also accelerates wear.

Ruts: holes, ridges, or scaling of the track

Wet: a condition where the surface has moisture on it or in it.

Blue Groove: rubber is laid creating a dark groove.

Sand/Soil: loose sand or topsoil covers parts of the surface.

Broken: the surface breaks up giving multiple conditions.

Tire Construction: Tires are a combination of the tread/carcass design and the rubber compound. The construction/tread affects the way the tire reacts to directional loading and how it presents the compound to the track surface. The compound affects the way a tire handles surface irregularities as well as the friction or bite as it contacts the surface.

Compounds

Silver (S);The most common and reliable Team Losi compound works well under varying conditions and is exceptional on blue-groove and soft surfaces.

Red (R); The Team Losi soft compound that picks up where Silver stops, this soft/sticky formula works well on dry, hard, slick surfaces.

Pink (P); The newest Team Losi soft compound that offers traction similar to Red with handling characteristics similar to Silver.
