Most RC racers know tire prep matters. Few actually do it right.
Whether you're running oval, dirt, or carpet, your tires are the single biggest variable between a podium finish and spinning out in turn two. Here's exactly how to prep them — and the mistakes that are costing you lap times.
Why Tire Prep Matters
Stock tires straight out of the bag are stiff, inconsistent, and nowhere near their performance potential. Tire prep penetrates the rubber compound, softening it at a molecular level to increase the contact patch and maximize grip from the very first lap.
Skip it, and you're leaving traction — and positions — on the table.
What You Need
- A quality tire prep solution (we use Dysfunctional Juice Tire Prep)
- Clean lint-free applicator or brush
- Zip-lock bags or tire bags
- Gloves
Step-by-Step: How to Prep RC Tires
1. Clean the tires first
Wipe down each tire with a clean cloth to remove any dust, mold release, or residue. Prep won't penetrate properly on a dirty surface.
2. Apply the prep evenly
Using your applicator, coat the entire tread surface with a thin, even layer. Don't glob it on — more isn't better. Consistency is.
3. Bag them immediately
Place each tire in a zip-lock bag right after applying. This traps the prep and forces it into the compound instead of evaporating.
4. Let them soak
This is where most racers rush it. Let your tires soak for a minimum of 2–4 hours. Overnight is better. The longer the soak, the deeper the penetration.
5. Wipe and race
Pull them out, give each tire a quick wipe to remove surface residue, mount up, and go. You'll feel the difference immediately.
Pro Tips
- Prep your tires the night before race day — never the morning of
- Store prepped tires in bags until you're ready to mount
- Re-apply between heat races if conditions are slick
- Different tracks and compounds may need different soak times — experiment and log your results
The Bottom Line
Tire prep isn't a shortcut — it's a fundamental part of a fast setup. Do it consistently, do it right, and you'll have a traction advantage before the tone even sounds.
