my rear driver side tire was flat when i got out of work, so i put the spare on and drove home. (less than a mile) i am getting all new tires put on, but i have to dirve to my buddy's shop like 20 miles away. i didnt want to drive on the spare, so i thought i would steal a wheel from my moms civic. my tires are 185/60/14, hers are 185/65/14. would that be better than the spare? i would think the spare is way smaller plus, not as safe to drive on. thanks in advance for your opinions.
