3TA — Tires, rear, 215/85R16 E. This code identifies the factory tire specification, application, or spare-wheel equipment. Browse RPO codes →
I am considering a used 2017 Cadillac CT5. The seller says it has the equipment associated with 3TA, and the code description is “Tires, rear, 215/85R16 E. This code identifies the factory tire specification, application, or spare-wheel equipment” What physical details should I inspect to make sure the listing is accurate?

I would avoid buying retrofit parts until the connectors and module support are confirmed. Returning electronic or VIN-programmed components can be difficult.

A window sticker is helpful for customer-facing option names, while the build sheet is usually more detailed. If they disagree, the vehicle-specific dealer equipment list can help connect the sales name to 3TA.

The safest interpretation is the one tied to the exact VIN, model year, platform, and market. In general, 3TA matches “Tires, rear, 215/85R16 E. This code identifies the factory tire specification, application, or spare-wheel equipment” but the included hardware can vary between applications.

I have seen this on a similar Cadillac CT5. The basic description was correct, but one related feature was part of a separate package. I would not assume the code includes every item mentioned in marketing material.

That code should be read as a factory configuration identifier, not necessarily a guarantee of a separate dashboard control. Some equipment operates automatically or is bundled with another system.

Some codes are reused across several brands, but that does not always mean the parts are identical. Model, trim, drivetrain, and production date can all matter.

If the feature is listed but not working, scan all related modules before assuming it was removed. A stored fault, replacement module, or configuration mismatch can make original equipment appear absent.
