Michelin 235/45ZR18 98Y XL PILOT SPORT 4 (ST) [ACU] T1

This is the Michelin Pilot Sport 4 Acoustic T1, a Tesla-approved summer tyre listed as original equipment for the Model 3 with 18-inch wheels.

• T1: Tesla-specific homologation.
• foam to reduce tyre cavity noise inside the cabin.
• 98 load index: 750 kg per tyre under specified conditions.
• Y speed rating: up to 300 km/h. This is plain Y, not the parenthesised (Y) rating.
• XL: Extra Load construction.
• Runflat: no.
• ST: I haven’t verified Michelin’s exact definition for this suffix, so I wouldn’t expand it in your listing.

The exact T1 version is listed by the supplier with EU ratings of fuel efficiency B, wet grip A and external noise 70 dB, class B. Confirm these against the supplied tyre’s label or product code before adding them to your product page, as the T0 and unmarked PS4 versions have different ratings.
