ST-Rated Trailer Tire Built for High-Load Cycles, Hydroplaning Resistance, and Long Tread Life
The Maxxis M8008 Plus ST Radial in ST225/75R15 10PR is engineered from the ground up for trailer use, with every design decision oriented toward load capacity, durability, and highway stability rather than passenger car comfort. This tire is rated for a maximum single load of 2,830 lbs at 80 PSI, making it appropriate for heavy boat trailers, utility trailers, enclosed cargo trailers, and fifth-wheel RV applications where a 15-inch rim is specified.
The M8008 Plus uses a premium dual-cord body casing design that substantially improves casing strength compared to single-cord constructions. The reinforced sidewall engineering maintains the ideal tire shape under continuous high-load cycles, resisting the sidewall flex that generates heat in trailer tire applications. Maxxis incorporates premium anti-oxidant agents into the tread compound to protect against weather cracking and ozone degradation during long-term outdoor storage.
The nondirectional rib tread pattern of TL00096900 maximizes resistance to hydroplaning by channeling water away from the contact patch efficiently. The rib design also minimizes the irregular wear patterns that develop when trailer tires operate without the self-correction of a steering axle.
Speed and Load Ratings
TL00096900 carries a Load Range E (10-ply rated) designation, a Load Index of 117/112 (2,830 lbs single), and a Speed Rating of N (87 mph). Per TRA trailer tire guidelines, standard load and pressure specifications are calibrated for 65 mph operation. For sustained highway speeds above 65 mph, increase inflation pressure by 10 PSI (not to exceed 80 PSI maximum). For operation between 76 and 85 mph, increase inflation by 10 PSI and reduce the load by 10%.

Frequently Asked Questions
Can I use TL00096900 on a passenger car or light truck?
No. ST-rated tires like TL00096900 are designed exclusively for trailer use. The construction and speed rating are not appropriate for steering or drive axles on passenger vehicles or trucks.
What trailer types is this tire appropriate for?
The Maxxis M8008 Plus TL00096900 is used on boat trailers, utility trailers, enclosed cargo trailers, travel trailers, and fifth-wheel RVs using 15-inch rims with a maximum load capacity requirement up to 2,830 lbs per tire.
What is the maximum speed for TL00096900?
The speed rating is N, which indicates 87 mph. However, ST trailer tire standards call for standard load/pressure ratings at 65 mph. At speeds above 65 mph, adjust inflation and load per TRA guidelines.
Does the M8008 Plus use a tube?
No. TL00096900 is tubeless (TL) and should be mounted without an inner tube on a rim sealed for tubeless applications.
What rim widths are compatible with ST225/75R15?
The approved rim width range for TL00096900 is 6.0 to 7.5 inches. Do not mount on rims outside this range.
How often should I check tire pressure on a trailer?
Check cold inflation before every trip. Trailer tires are not driven regularly and lose pressure during storage periods. Under-inflation is the primary cause of trailer tire failure.
How long do trailer tires last?
Maxxis and industry guidelines recommend replacing trailer tires every three to five years regardless of tread depth. UV exposure, ozone, and heat cycling degrade the rubber compounds even when the tires are not in use.
Is this tire sold individually or as a pair?
TL00096900 is sold as a single tire. Order the quantity required for your trailer axle configuration.
Installation Instructions
- Always have trailer tires mounted by a qualified tire technician using professional bead-seating equipment.
- Confirm the rim width is within the approved 6.0 to 7.5 inch range for ST225/75R15 fitment.
- Inflate TL00096900 to 80 PSI cold for maximum load capacity, or as specified for your trailer’s GVWR.
- Check cold inflation before every tow, as trailer tires are not driven daily and may lose pressure between uses.
- Torque lug nuts to the trailer axle manufacturer’s specification, typically 90 to 120 ft-lb depending on stud size.
- Inspect tread depth and sidewalls before each tow season. Replace tires showing cracking, sidewall bulging, or tread depth below 2/32 in regardless of apparent age.
- Maxxis and industry standards recommend replacing ST trailer tires every three to five years regardless of tread depth, due to UV and ozone degradation.
