Nah. Nothing even remotely modern enough to have a donut spare is 5x4”. And while 5x100mm is close, it is not close enough. Not IMO anyway.
I gave up carrying a spare locally. If I end up with a flat in a safe enough spot to change a tire I can just wait for my AAA tow. And if I’m not in a safe enough spot to stay and wait, I’m definitely not in a spot where I’m gonna get out and change a tire. Worst case I have to limp it along for a bit and ruin a rim. Well, rims are easy enough to replace. So many people and good samaritans get hit by cars doing things like that it’s not worth it anymore. Hang out on the side of a highway with cars whizzing by changing a tire with a sketchy jack on uneven ground? No thanks. I’ll just sit and chill in my car, listen to music and wait for the tow. The freeways I drive would be the worst spots for a flat, but most of the time on them the tow will be just as fast, if not faster, than changing the tire because of the freeway patrol rigs they run during commute time.
And that’s all a donut spare is good for anyway, get you off the freeway to a tire shop. So many insurance policies have some kind of emergency towing now it’s not even worth it. Heck I think I payed $100 for my spare, that alone would cover the tow most of the time.
