| Tire Compound Based on Vehicle Weight
Have a question for y’all. My young son and I are building an Enduro kit. As of now, I expect the finished weight of the truck to be between 6-7 pounds. Based on where we live (Norhteast Ohio) and the fact it’s been raining a lot lately and the trails are constantly wet, we were thinking of either Pro-Line Hyrax or Super Swampers XL tires. The question is about tire compound—Predator or G8? I’m thinking Predator because the P-L tire chart says it’s better for wet terrains and lower temps (it’s between 50-60 degrees F most days right now). But then I began wondering at what point (or vehicle weight) do you want to use a stiffer compound to support the truck. For reference, we’re also using CI 4.5 inch foams with standard inners and soft front/medium rear compounds. So what do you guys think? Thanks! |

I also live in the Northeast and I ran Predator Hyrax side by side with G8 Hyrax. The Predator compound is definitely better on wet rocks. Everywhere else they're pretty comparable. I like Predator. Obviously, they aren't going to last as long as the G8.

I just didn’t know if a 5 lb. and a 10 lb. or heavier truck could work equally well with the same compound tire. In theory, I would think that maybe heavier vehicles would benefit from tires with a stiffer compound. Like, maybe the carcass wouldn’t compress too far like possibly with a softer tire, if that makes sense. But I don’t know. | |

Some guys think the Predator compound is too soft because the tread will sometimes fold back instead of remaining stiff and gripping the rocks. I've seen mostly guys on the west coast complaining about this. Hot weather and heavy rigs would amplify this. Also, their rocks are like sandpaper and they appear to have more grip than the smoother rocks we have here in the East coast. I haven't experiencing the tread folding with Predator. I have experienced it with RC4WD X2S3 compound MT/R tires. | |

Based on your location I would say probably Predator. A lot of the east coast guys seem to like that compound better over there. On the West Coast we prefer the G8 compound, even on lighter rigs. Mines 5.5 lbs. |

Tire width i also find to be more important than i had originally thought. Most of my rigs perform better with a fairly narrow tire on the rocks

Foam selection is weight dependant. Tire compound selection is temperature dependant.
