Purcell Tire & Service in Tremonton, UT

Three alignment services at one store is unusual, and together they cover most of what rolls through northern Utah.

Car and light truck alignment for pickups and vans. Heavy-duty truck alignment for tractors. Trailer alignment for what is behind them.

The last of those is the one fleets skip and should not. A trailer that tracks crooked drags the tractor's drive tires sideways for every loaded mile, and the driver feels nothing. Aligning the tractor and leaving the trailer fixes the half you can see.

All nine tire categories are carried, including agricultural and tracks for the machinery of the valley, and OTR for the equipment on construction and aggregate sites.

OTR services covers fitting, change-outs and repairs on those tires, and wheel refurbishing deals with the wheels under them, which take the same punishment and are usually repairable when they look finished.

Casings go to the Purcell retread plant in Salt Lake City and come back ready to run. See retreading.

Tremonton and Ogden between them cover northern Utah, and their lists are close but not identical. Knowing the gaps saves a drive.

Tremonton has, and Ogden does not: OTR services, for fitting, change-outs and repairs on off-highway tires.

Ogden has, and Tremonton does not: mobile service, suspension repair and state inspections.

Everything else, roadside assistance, fleet accounts, alignment on cars, trucks and trailers, retreading, balancing and wheel refurbishing, is at both. Neither does brakes, oil changes, A/C or engine work, which are at Orem and Salt Lake City.
