Can I use the tires on my old car as a spare for my new car?

Well,

The newer tires are a lower profile and on larger rims.

Overall the difference in outside diameter is not going to be that much of an issue but it may affect your handling.

As long as the wheels fit properly on the hubs I think it would work at least as well as the dough nut spare.

you would have to try the old wheel and see how it drives.

There may be mroe issues if you have the spare on the front...

It would still be best to have the same tires all round as soon as practical .

Good luck !

The size of the rim is what makes the difference, meaning the 93 tire is slightly smaller. But a donut tire is much smaller so it doesn't matter, so as long as the rim fits the lug nut posts of the wheel. Just remember to use it only for a spare. As for other parts, if you can't determine what is reusable between the seven years of the vehicles, why bother with potential problems of used parts in the future?

You would need to replace both the wheels and tires. If the bolt pattern on the wheels is the same size you could use them

i suggest you can buy new car
