Commercial and fleet vehicles need tires rated for their actual load, not just their wheel size — a cargo van and a box truck can share a tire diameter but carry different load ratings. Seattle Tire Shop services fleet and commercial vehicles across its 14-area coverage zone around Seattle; ask about load range and ply rating before matching a tire to the vehicle.
A tire's size tells you what fits on the rim. It doesn't tell you what the tire is rated to carry, and that's the number that actually matters on a commercial vehicle. Two tires can measure the same and still have different load ranges, which is why a passenger-rated tire on a work van that's loaded every day wears unevenly or fails early even though it "fit."
Seattle Tire Shop covers fleet and commercial tire needs across several service areas around Seattle, which matters for a fleet running vehicles out of more than one lot or job site.
What makes a commercial tire different from a passenger tire?
Load range and ply rating are the numbers to ask about, not just the tire size printed on the sidewall. A heavier-duty carcass holds its shape under a loaded trailer hitch or a full cargo box in a way a standard passenger tire wasn't built for, even at the same tread pattern and diameter.
Does a mixed fleet need the same tire on every vehicle?
Not usually. A fleet running pickups, cargo vans, and a box truck or two is really running three different load categories, even if the paperwork lumps them together as "company vehicles." Matching each vehicle to its correct load range matters more than standardizing on one tire brand or model across the fleet.
What should a fleet manager ask about before switching tire providers?
Ask whether quoted pricing is per vehicle class or a flat rate regardless of load range — a flat rate across a mixed fleet usually means someone is overpaying on the lighter vehicles or underbuilt on the heavier ones. It also helps to ask how tread wear is tracked across the fleet over time, since uneven wear on one vehicle often points to an alignment or load issue worth catching before it shortens the life of the next set.
Do you service vans and pickups, or only larger trucks?
Commercial and fleet tire service generally covers the full range, from pickups and cargo vans up through box trucks, as long as the correct size and load rating are available for the vehicle. Call ahead with the vehicle's tire size and load rating to confirm.
What is a load range, and why does it matter for a work vehicle?
Load range tells you how much weight a tire is built to carry at a given pressure, and it's separate from the tire's size. A work vehicle loaded daily needs a tire rated for that actual load, not just one that physically fits the rim.
Can mismatched tires across a fleet cause problems?
Yes — tires with different tread depths or load ratings on the same vehicle, or across similar vehicles in a fleet, wear unevenly and can mask an alignment problem. Rotating and checking tread depth on a regular basis catches this before it turns into a bigger repair.
