Ok to run 17”’spare with 16” mains?

I had 17 wheels and spare and went to 16”. I haven’t been able to pick up a 16” wheel for my spare

am I ok to run 285/75/16 as my normal tires and then use a 285/70/17 as my spare since same diameter

I think it’s fine just want to confirm

 

Yep as long as the total diameter is the same you’re good. You could even get away with a mismatched spare to limp to a shop if you had to.

 

Thanks. Just looking to find a cheap
Used tire for a spare since I don’t have one. Then search for a matching tire and wheel when I get the carrier on back

 

Yep, you will be good to go.

 

Any chance you're in socal?

 

No I’m in Phoenix

 

That's too bad, we could have traded spares. I have the opposite problem. 16" spare, swapped to 17" wheels.

 

Damn, if you were close to PA I would trade you my 16" for 17".
