MERXENG trailer tires are a solid choice for utility and garden trailer use — the key reason being DOT-approved, 6-ply Load Range C construction rated to 960 lbs per tire at 90 PSI, which covers the load envelope most utility trailer owners actually need.
MERXENG trailer tires are bias-ply ST-type tires built for moderate-speed hauling on flatbed, utility, and garden trailers — not sustained highway towing at 70 mph. The DOT approval stamp matters in a category where plenty of no-name imports skip that certification entirely. MERXENG tires also frequently ship pre-mounted on 12-inch rims with a 5-lug, 4.5-inch bolt pattern, eliminating the tire shop step most buyers would otherwise need.

How to Choose
- Pick MERXENG 4.80-12 if: you're running a utility, garden, or flatbed trailer at moderate speeds and need DOT-approved Load Range C tires delivered pre-mounted.
- Pick a Load Range D or E radial if: you're towing a boat or enclosed cargo trailer on the highway regularly at 65–70 mph — bias-ply construction isn't built for that sustained speed envelope.
- Pick MERXENG pre-mounted sets if: your existing hub matches a 5-lug, 4.5-inch bolt pattern and you want to skip the tire shop entirely on replacement day.
- Pick a different size if: your trailer calls for a larger ST-size like ST205/75D15 — verify your trailer's placard before ordering the 4.80-12.
- Pick MERXENG over unbranded imports if: DOT approval is a non-negotiable for your state registration or peace of mind — many low-cost alternatives don't carry that stamp.
