I saw some real photos and videos of Xiaomi SU7 Ultra where the tire sidewall has an "R" marking. Can such tires support a top speed of 350km/h?

Question

The display car's tires are not the final mass-production version; the mass-produced version will use ZR-structured tires capable of speeds over 300km/h.

Accepted Answer

Currently, all Xiaomi SU7 Ultra display cars are in the VP stage, i.e., the validation production phase, and are not the final mass-production versions. Therefore, some details differ from the mass-produced version, including the tires.
The final mass-produced version will use tires with a "ZR" structure type and a speed rating of "Y", which can meet speeds above 300km/h. The tires for Xiaomi SU7 Ultra have undergone thorough testing and obtained national mandatory regulation certifications, so you can use them with confidence.
