Big Rock Venting My Belted MX28 Tires

[JordanBR]

Hey Guys im Wondering If I should melt a hole in my belted mx28 to vent I'm currently running them fully sealed and when they go outside the -5 Celsus makes the air inside them shrink and the tires are basically flat lol so wondering what I can do without compromising the belt

Thanks Guys

Vent the outsides, 2 holes, one opposite the other and tape up the inner holes on the rims if there are any.
