Trailer Tires & Wheels (ST) for Sale in Laval, Quebec
Location Remorque Laval is your source for special trailer (ST) tires, rims, and complete tire-and-wheel assemblies for utility, cargo, boat, and RV trailers. Choosing the right trailer tire is not the same as buying a car tire: ST tires are engineered specifically for towing, with reinforced sidewalls that resist sway and heat, plus load ratings built to carry heavy vertical weight over long distances. Fit the wrong tire and you risk premature wear, poor handling, or a blowout on the highway. Our team helps you match the correct size, load range, and speed rating to your trailer and its gross weight, so every load rolls safely. We stock the most common ST sizes and wheel bolt patterns, and we ship trailer and RV parts across Quebec with free delivery on orders over $300. Prefer in-person service? Visit our shop at 1870 rue Cunard in Laval, where we also handle mounting, balancing, repairs, reinforcement, and custom modifications for customers throughout Laval, Montreal, and the North Shore. Call 450-232-7828 for advice on the right setup for your trailer.
ST vs. LT tires: why the difference matters
The letters at the start of a tire size tell you what the tire was built for, and it makes a real difference in safety.
- ST (Special Trailer) tires have stiff, reinforced sidewalls that control trailer sway and are engineered to resist the heat buildup that causes blowouts during towing. They carry higher load capacities than comparable passenger or light-truck tires.
- LT (Light Truck) tires are designed for the powered vehicle. Their more flexible sidewalls favour ride comfort and traction, not the side-to-side stability a trailer needs.
While some LT tires carry a higher speed rating, that does not make them safer on a trailer. For most trailers, an ST tire is the correct choice. If you are unsure what your trailer originally came with, our staff can identify the right replacement for your axle and weight rating.
Load index and load range explained
Every trailer tire has a maximum load capacity, and matching it to your trailer's fully loaded weight is critical. The load range letter indicates the tire's strength and its maximum inflation pressure:
- Load Range C — 6-ply rated, roughly 1,820 lbs per tire at 50 psi.
- Load Range D — 8-ply rated, roughly 2,150 to 2,540 lbs per tire at 65 psi.
- Load Range E — 10-ply rated, roughly 2,830 lbs per tire at 65 psi.
Add up the capacity of all your trailer's tires and confirm it exceeds the trailer's Gross Vehicle Weight Rating (GVWR), including cargo. When in doubt, size up in load range. Running tires near or over their limit is one of the most common causes of failure.
Common ST trailer tire sizes
Trailer tire sizes read as ST (width in mm)/(aspect ratio)R(rim diameter in inches). Some of the most requested sizes include:
- ST205/75R15 — one of the most popular utility and boat-trailer sizes, available in Load Range C and D.
- ST225/75R15 — a step up in width for heavier tandem-axle trailers.
- ST175/80R13 and ST205/75R14 — common on smaller utility and cargo trailers.
- ST235/80R16 — used on heavy-duty and larger RV trailers.
Not sure which size you need? The information is molded into the sidewall of your current tire. Read it to us over the phone at 450-232-7828 and we will confirm the correct fit.
Wheels, rims, and complete assemblies
A tire is only half the setup. We supply trailer rims in the correct diameter, width, and bolt pattern (for example 5-on-4.5 or 6-on-5.5), in both steel and galvanized finishes for corrosion resistance on boat and marine trailers. Ordering a mounted-and-balanced tire-and-wheel assembly is the easiest option: it arrives ready to bolt on, with no separate mounting appointment needed. We also verify that rim width matches your chosen tire so the bead seats correctly and the tire performs as designed.
Winter and cold-weather considerations
Quebec winters are hard on rubber. If your trailer stays in service through the cold months, keep in mind that tire pressure drops as temperatures fall, so check inflation more often in winter. Cold, stiff rubber is also more prone to cracking under load. For trailers stored over winter, we recommend keeping tires inflated, off direct contact with damp or frozen ground, and out of prolonged sunlight to slow ozone and UV aging. Ask us about storage tips or bring your trailer in for a pre-season inspection.
Trailer tire maintenance and replacement
Trailer tires often fail from age and neglect rather than mileage, because trailers sit parked for long stretches. Protect your investment with a few habits:
- Check pressure before every trip and inflate to the pressure listed on the sidewall, not the tow vehicle's.
- Inspect for sidewall cracks, bulges, and uneven wear, which signal alignment or bearing issues.
- Replace tires every 5 to 6 years regardless of tread depth. The manufacture date is stamped on the sidewall as a four-digit DOT code (week and year).
- Do not mix tire sizes, types, or load ranges on the same trailer.
Beyond tires, our Laval shop handles repairs, maintenance, reinforcement, and custom modifications for trailers of all kinds. Whether you need a single tire shipped across Quebec or a full workover in person, we are here to help.
