You don’t need to buy a brand new car to buy smart car tires. The only thing that needs to be changed in your tires is their tread pattern. You can buy a low profile tire that matches your car, or you can buy a high profile tire that matches your car. The smart tires are the ones that will make your tires last longer and will have a better grip on the road.
I have a 2009 Jeep Grand Cherokee and its tires are on the high end of the smart tire spectrum. I had to replace them one time when I was having a lot of problems with the car in the winter. I had an accident, and a tire blew. I had to get a new one. The tires were expensive, but if you are going to spend $1500 on tires, you should at least get a good rubber.
