Hi Michelle, if you are referring to tyre repairs and replacement, yes they should be open. You might want to check with your preferred tyre shop just in case.
i don't think tyre shops are opened right now. Repairs might be available for emergencies. if you're buying tyres than different. the shop i go to www.amtyre.com lets me buy first than install after Cb is over. your shop might have different arrangements so better to check
