ADCOTriple Axle30-32" Tire DiameterADCO 3992 Black Triple Axle Tyre Gard -- 30-32" Tire Cover

Stop UV rays, weather, and ozone from cracking your RV sidewalls before your next trip. The ADCO Tyre Gard Triple Axle cover slips over three tires at once -- saving installation time and protecting your investment while the rig sits in storage or in the driveway.

One Cover, Three Tires, Zero Hassle

Tire sidewall cracking is one of the most preventable -- and most overlooked -- forms of RV wear. Exposure to UV radiation, ozone, and moisture dries out rubber compounds and causes micro-cracks that grow into blowout risks. The ADCO Tyre Gard triple axle cover is designed specifically for triple-axle trailers and coaches where installing individual tire covers on six tires per side would eat up 20 minutes of your time every trip.

The 30-32" size fits a wide range of common RV and trailer tires. Check your sidewall for the overall diameter before ordering -- this cover is built for tires measuring between 30 and 32 inches in diameter.

Heavy-Duty Vinyl Shell

Thick outer vinyl repels rain, road spray, and moisture to keep tire sidewalls dry during short-term and long-term storage.

Flannel-Backed UV Barrier

Soft flannel lining diffuses and blocks UV rays -- the primary cause of premature sidewall cracking and ozone degradation.

Triple Axle Single-Piece Design

Covers all three tires on one side of a triple-axle rig in a single installation. No juggling six separate covers per side.

Reinforced Construction

Overlapping seams, double-needle stitching, and reinforced grommets resist wind lift and hold shape through repeated use.

Why Tire Covers Matter for Stored RVs

UV radiation degrades rubber compounds even on overcast days. Ozone -- concentrated near motors, battery banks, and in urban air -- accelerates cracking at the molecular level. When a trailer sits for weeks or months, the sidewalls experience all of this with no ventilation or flexing to redistribute stress. A quality vinyl cover is the single most cost-effective step you can take to extend tire life and reduce roadside blowout risk.

Single-Piece Convenience: Rather than wrestling with three or six individual covers each time you park, the ADCO triple axle design lets you cover an entire side of a triple-axle trailer in one motion. On a typical triple-axle fifth wheel or toy hauler, that cuts tire-cover installation from 10-15 minutes down to 2-3 minutes per side.

Construction and Durability

The outer shell is heavy-duty vinyl selected for weather and UV resistance. The flannel backing prevents direct contact between the vinyl and the tire surface, reducing abrasion risk and adding an extra layer of UV filtration. Seams are double-needle stitched for strength, and the grommets are reinforced to hold up to wind stress without tearing free.

Fit Check: Measure your tire's overall diameter (not the wheel/rim diameter) to confirm fitment. The 30-32" range covers the diameter of the mounted tire from ground contact patch to top of tread. Common RV tire sizes in this range include ST235/85R16, ST235/80R16, and similar profiles -- but always measure rather than assume.

Storage and Maintenance Tips

Care Tips for Long Cover Life:
  • Wipe covers clean with mild soap and water before storing them.
  • Store covers loosely folded or rolled -- do not compress tightly, which can crack vinyl over time.
  • Inspect grommets and stitching each season for signs of wear.
  • Apply a UV protectant to the vinyl exterior annually to maintain flexibility.
Heads Up: This cover is designed for storage and driveway use. Do not tow or drive with the Tyre Gard cover installed on the tires. Remove covers before moving the vehicle.

Important Information
  • This cover is for stationary use only -- remove before towing or driving.
  • Measure your actual mounted tire outer diameter before purchasing. This cover fits 30-32" diameter tires. Ordering the wrong size is a common return reason.
  • Triple axle cover fits one side of a triple-axle vehicle -- order two covers (per side) for full protection on all six tires.
  • Do not store cover tightly folded or compressed for extended periods; this can cause vinyl cracking.
  • Inspect tire condition regularly even when covers are in use -- covers protect tires but do not substitute for routine tire pressure checks and age assessments.
