LEAD CATEGORY

Commercial Trailer Tires & Wheels

ST radial and bias trailer tires, commercial 17.5-inch options, steel and aluminum wheels, and mounted assemblies.

PROGRAM OVERVIEW

Source trailer tires and wheels against the whole specification.

RakSiam can supply tires as a standalone line, wheels as a matched program, or mounted tire-and-wheel assemblies. We build the quote from the vehicle load, tire size and service description, wheel geometry, inflation requirement, speed category, valve, packaging, and required markings—so the delivered assembly matches the application rather than merely sharing a diameter.

Utility, cargo, landscape, and boat trailers

RV, toy-hauler, and fifth-wheel programs

Equipment, dump, and gooseneck trailers

OEM production, dealer, and aftermarket distribution

CONFIGURATION

What we define before we quote.

A useful alternative must match the critical interfaces and performance requirements. These are the normal starting points for this category.

FAQ

Common questions on this category.

Can RakSiam supply complete tire-and-wheel assemblies?

Yes. We can quote mounted assemblies with the tire, wheel, valve, mounting orientation, inflation, balance requirement, labels, and pallet pattern defined in one approved specification.

Which trailer tire sizes can you source?

Programs commonly cover 13 through 16-inch ST fitments and selected commercial 17.5-inch applications. Availability, minimums, construction, service description, and origin are confirmed for each quote.

Can you cross our current wheel?

Yes. We need diameter, width, bolt circle, pilot, offset, rated capacity, finish, valve-hole specification, and either a drawing or approved sample. A matching diameter alone is not sufficient.

Are tire markings and regulatory documents included?

We define required markings and supporting factory documentation during qualification. The buyer remains responsible for approving the tire and wheel fitment for the vehicle and market.

Availability, origin, MOQ, lead time, tariff treatment, technical suitability, and regulatory documentation are confirmed for the specific quoted program. The information above is not an engineering certification or a tariff determination.
