My tire blew and out a big donut on (its a bigger spare I guess?)

Ordered new tire to be put on

It won’t be here for a week…(I live in small town)

I don’t know anything about cars …

My tire blew and I had the spare put on by roadside assist tow company . The guy said I’m lucky I have a bigger donut but it’s still dangerous and shouldn’t be driven over 50 more than 20 miles….

My car is a 2009 Toyota Venza AWD

He said it could ruin the axel/transmission if I drive on it

It’s snowing and there’s foot of snow on the ground/snow covered roads …

can anyone give me any input on how my situation.

I work 2 jobs everyday about…10 miles to work

Can I drive with spare for a week if I go slow?
