In order for the system to associate your offer on Yandex.Market with the product profile, you must specify:
width of the tire profile
All these parameters are required and they must be specified in the product offer title.
The first parameter specified in the product offer is the manufacturer, then the line, then all other parameters in any order.

Parameters omitted or incomplete.
Pirelli Chrono 205/75 Pirelli 195/75 R14 106R
The offer for Pirelli Chrono 205/75 C only specifies part of the mandatory parameters for tires. Without complete information, this model fits two product profiles: Pirelli Chrono 205/75R16C 110R or Pirelli Chrono 205/75R14C 109S. The system doesn't have enough data to associate the offer with a product profile.
Tire models from different lines may have the same width, series, and other parameters. So the offer Pirelli 195/75 R14 106R might match any one of three product profiles: Pirelli Chrono 195/75 R14 106R, Pirelli Citynet 195/75 R14 106R or Pirelli Citynet Camper 195/75 R14 106R. This is why it is important to specify all the tire parameters (including the line) — otherwise, the system won't be able to recognize the model.
