How long can you drive on a donut tire?

Look I really need a number of miles i can go. I've heard 500 and 1000 miles. I'm driving on a new donut on the back right tire in a 08 honda crv. I'm going 45mph or less at all times. Drive on paved roads.

Should I keep or trade in my car?

I have a 2011 Honda CRV with 95k miles on it. I still owe about $9k to finish at the end of 2018.

I'm wondering if, because the miles are getting high, I should try to trade this in for like a newer model - 2014 for that vehicle go for about $17k with 30k miles.

The immediate benefit is that my payments would decrease, but of course I will have to maintain a payment over a longer period of time. Still, the $9k I owe represents about half of what I would pay for the newer vehicle with fewer miles.

I've been trying to weigh the options, can you help?

Do you think CVT transmission is bad?

I'm truly in love with the 2017 Honda CR-V except for the CVT. I've heard so many horror stories about it that I may buy another car because of it.

So do you think CVT is bad or am I worried for nothing?
