1.0 Product Overview
What it is: A proprietary silicone-polymer tire and trim dressing. Does not contain Prop 65 chemicals. 100% mixed, bottled, and packaged in the USA.
Primary use: A spray-on dressing that coats tire sidewalls to provide UV protection, hydration, and a customizable shine (high-gloss wet look or satin finish). Also works as a dressing for wheel wells, interior and exterior rubber, plastic, and vinyl trim surfaces.
Yield: A small amount goes a long way. One 18 oz bottle provides many applications when applied at the recommended rate using the included applicator.
Longevity: Durability varies depending on climate, washing frequency, and driving conditions. This is not a permanent coating, but when applied correctly, it will withstand normal conditions including rain. Reapply when shine diminishes.
Shelf life: 1.5 to 2 years when stored properly. Store upright in a cool, dry place (ideally 50–60°F / 10–16°C). Keep above freezing and out of direct sunlight.
Chemical base: A water-based, 0% VOC, silicone-polymer formula. The primary active ingredient is polydimethylsiloxane (approximately 48–52%), combined with water and trace formulation additives. Contains no petroleum distillates. Unlike most dressings on the market, this formula will not dry out or crack rubber with prolonged use. Note: This is a commercial chemical product — causes serious eye irritation (GHS Category 2A). Harmful if swallowed. Keep out of reach of children.
Kit Contents (18 oz Kit):
1x CAR GUYS Tire Shine Spray — 18 oz
1x CAR GUYS Tire Shine Applicator
2.0 Application Instructions
Prep (First-Time Use): Deep clean tires with CAR GUYS Wheel Cleaner or CAR GUYS Super Cleaner to strip any existing dressings — especially petroleum-based products from other brands that may interfere with bonding. Rinse thoroughly and dry completely before applying.
Prep (Routine Use): Clean tires with a dedicated wheel cleaner. Ensure tires are clean and completely dry before application.
Apply (Applicator Method — Recommended): Shake bottle well. Spray product onto the included Tire Shine Applicator a few times and massage onto the tire sidewall to create a thin, even layer. This method gives the most control over coverage and prevents drips onto the driveway. Product applies milky in color and turns clear when dry.
Apply (Direct Spray Method — For Maximum Gloss): Lightly spray product directly onto tire sidewalls. Wipe off any overspray and leave to air dry. Use this method when a higher-gloss wet look is desired.
Finish (High-Gloss Wet Look): Leave the product to air dry completely. Do not wipe.
Finish (Satin/Less Glossy Look): Wait approximately 10 minutes, then wipe off excess with a clean, dry microfiber towel.
Before driving: Always inspect the tire and wipe away any excess product from rims, tire sidewall grooves, and tire tread grooves. Failure to do this will cause product sling (product flinging onto paint, fenders, and wheel wells while driving). Allow a minimum of 10–15 minutes of dry time before driving.
For additional gloss: Apply a 2nd layer after the first coat has fully dried.
Tool care: See the Accessory Care Guide, Section 6.0 (Cleaning — Tire Shine Applicator), for full cleaning and storage instructions for the Tire Shine Applicator.
3.0 Safe Surfaces & Warnings
Safe on: Tire sidewalls, wheel wells, rubber trim (interior and exterior), plastic trim (interior and exterior), vinyl trim (interior and exterior), dashboards, door panels, center consoles, tonneau covers (rubber, vinyl, or plastic types only).
Do NOT use on:
Tire tread (creates a dangerously slippery driving surface — safety hazard).
Motorcycle tires (creates a slippery surface — safety hazard).
Bicycle tires (creates a slippery surface — safety hazard).
Steering wheel (polymer residue makes the grip dangerously slick — safety hazard).
Brake pedals, clutch pedals, or shift knob (same reason — safety hazard).
Fabric or upholstery (not designed for porous textile materials).
Concrete driveways or pavers (allowing excess product to drip onto concrete can leave dark staining that is difficult to remove).
Application temperature: No specific temperature limits. The only requirement is that the tire surface must be clean and completely dry before application.
Sun exposure: Can be applied in direct sunlight. For best results, work in shade or a garage for the most even finish and easiest application.
Dilution: Ready to use. Do not dilute.

4.0 Troubleshooting & FAQs
Why is the product slinging onto my paint while driving?
Over-application or insufficient dry time. Sling occurs when excess product is flung off the tire sidewall onto the vehicle's paint, fenders, and wheel wells during driving. To prevent: apply thin, even coats using the applicator (not direct spray). Before driving, always wipe away any excess product from rims, tire sidewall grooves, and tread grooves. Allow a minimum of 10–15 minutes of dry time before driving.
Unprepped tires. If the tires still have residue from old petroleum-based dressings, the new product won't bond properly and can fling off even at correct application amounts. Deep clean the tires with CAR GUYS Wheel Cleaner or CAR GUYS Super Cleaner using a stiff-bristle brush before the first application of Tire Shine.
Why does the product look milky when I apply it?
This is normal. The product applies milky/white in color and turns clear as it dries. If it still appears milky after drying, the surface may not have been fully clean or dry before application — clean the tire and reapply.
Why do my tires look brown?
The most common cause is antiozonant blooming — a normal process where protective waxes built into tire rubber slowly migrate to the surface over time. These waxes shield the rubber from ozone and UV damage, but once they reach the surface they oxidize and show up as a brown haze or film. This happens on any tire as it ages, regardless of whether any dressing was used.
A hydrated, shiny surface can make existing bloom much more visible than a dry matte sidewall did — so browning that was already there can appear to "show up" after any dressing is applied, including ours. Heavy residue from petroleum-based dressings previously used on the tire can also build up and discolor over time.
Tire Shine does not remove brown staining — it's a dressing, not a cleaner. To remove it, deep clean the tires with CAR GUYS Wheel Cleaner or CAR GUYS Super Cleaner using a stiff-bristle brush. Perform at least 2 rounds of scrubbing and rinsing until the sidewall comes back to a uniform dark finish. Dry completely before reapplying Tire Shine.
Does the glossy finish attract more dirt or dust?
The coated surface may attract slightly more dust than bare, uncoated rubber. This is normal with all polymer/silicone-based tire dressings and is not a product defect. Regular washing will remove any accumulated dust, and the UV protection benefits significantly outweigh the minor dust attraction.
Will rain wash it off immediately?
No. When applied correctly to a clean, dry tire, the product bonds to the surface and will withstand normal rain. However, this is not a permanent coating — repeated heavy washing or prolonged exposure will gradually diminish the shine. Reapply as needed.
Do I need to strip old tire dressing before using this product?
Yes, for best results on the first application. Old dressings — especially petroleum-based products from other brands — can prevent proper bonding. Deep clean tires with CAR GUYS Wheel Cleaner or CAR GUYS Super Cleaner before the first application. After the initial strip, routine wheel cleaning between applications is sufficient.
How do I get a high-gloss wet look vs. a satin finish?
High-gloss wet look: Apply the product and leave it to air dry completely. Do not wipe. For maximum gloss, spray directly onto the tire sidewall (instead of the applicator), wipe off overspray, and let air dry. A 2nd coat after the first has dried will further increase depth and gloss.
Satin/less glossy finish: Apply the product, wait approximately 10 minutes, then wipe off the excess with a clean, dry microfiber towel.
How do I get into the nooks and crannies of all-terrain tires?
Lightly spray the product directly onto the tire, then go over it with the applicator to even it out and wipe off any overspray or excess puddles. If no over-application occurred, allow 10–15 minutes of dry time before driving.
Can I apply this with a buffer or machine?
No. This product is designed for hand application only (applicator or direct spray and wipe).
Can I layer the product for more shine?
Yes. Apply a 2nd layer after the first coat has fully dried. Each additional coat increases depth and gloss.
How long does the shine last?
Durability varies depending on climate, washing frequency, and driving conditions. This is not a permanent coating, but when applied correctly it will withstand normal conditions including rain. Reapply when shine diminishes.
How often should I reapply?
Reapply whenever the shine diminishes. There is no maximum application frequency. Typical triggers for reapplication include washing the vehicle, heavy rain exposure, or visible fading.
Is it safe for wheels and rims?
The product is designed for tire sidewalls, wheel wells, and rubber/plastic/vinyl trim — not for rims. If overspray gets on your rims, simply wipe it off. It will not damage the rim surface, but it serves no purpose on rims and may leave a slippery residue. This is a dressing, not a wheel or tire cleaner — clean tires and rims with a dedicated wheel cleaner before applying.
Can I use this on my dashboard and interior trim?
Yes. Safe for interior plastic, vinyl, and rubber surfaces including dashboards, door panels, and center consoles. Apply a thin coat and buff off all excess with a microfiber towel to avoid a greasy feel. Do NOT apply to the steering wheel, brake/clutch pedals, or shift knob — the polymer residue makes these surfaces dangerously slippery.
Can I use this on a tonneau cover?
Depends on the material. If the tonneau cover is made of rubber, vinyl, or plastic, yes — apply a thin coat and buff off all excess with a microfiber towel to prevent rain runoff. If the tonneau cover is fabric or canvas, no — the product is not designed for porous textile materials.
Can I use this on motorcycle or bicycle tires?
No. The product is not meant for motorcycle or bicycle tires. The coating creates a slippery surface that is a serious safety hazard on two-wheeled vehicles that rely on tire grip for stability.
Can I apply Tire Shine to the tire tread?
No. Never apply to tire tread. The product creates a slippery surface that will reduce traction and is a serious safety hazard.
I accidentally got Tire Shine on my paint — will it damage it?
No. The product will not damage automotive paint. Wash the affected area with standard car wash soap and water to remove any residue.
The product dripped onto my driveway and left a dark spot — how do I remove it?
Excess product that drips onto concrete or pavers can leave a dark stain. Use the included Tire Shine Applicator rather than direct spray to maintain precise control and prevent drips. If staining has already occurred: scrub the spot with dish soap (Dawn) and a stiff-bristle brush. Rinse and repeat as needed. For stubborn stains on porous concrete, apply a concrete degreaser, let it dwell per the degreaser's instructions, then scrub and rinse. Fresh drips can be absorbed with cat litter before cleaning.
Is this product silicone-based?
Yes. The primary active ingredient is polydimethylsiloxane (a silicone polymer) at approximately 48–52%, combined with water and trace formulation additives. This is what gives the product its durable bond and UV-protective properties on rubber, plastic, and vinyl. Unlike petroleum-based or solvent-based dressings, silicone-based formulas protect rather than degrade the treated surfaces.
Is this product safe around kids and pets?
Keep out of reach of children — this is a commercial chemical product with a GHS Category 2A eye irritation classification. Once the product is fully applied and dried on the tire, there is no residue transfer concern for children or pets under normal circumstances. During application and while the product is still wet: keep children and pets away, apply in a well-ventilated area, avoid eye contact, and wash hands afterward. Acute oral toxicity testing shows the formula has low acute oral toxicity at normal exposure levels, but if ingestion occurs, medical attention is still recommended — contact your local poison control center.
Does Tire Shine provide UV protection?
Yes. The formula contains a proprietary polymer additive that hydrates the surface and provides durable UV protection against fading, browning, and cracking caused by sun exposure.
Will this product dry out or crack my rubber?
No. Unlike many popular dressings that contain petroleum distillates — which cause rubber to dry and crack with prolonged use — this silicone-polymer formula is designed to rejuvenate and protect rubber, plastic, and vinyl. It prolongs the life of treated surfaces.
Is Tire Shine the same as Plastic Restorer? Which should I use?
They serve different purposes. Tire Shine is optimized for tire sidewalls and provides a customizable gloss level (wet look or satin). Plastic Restorer is more durable for exterior plastic and trim that faces heavy weathering. For dashboards and interior trim, either product works — Plastic Restorer may last longer on exterior-facing surfaces.
