No more track time Jon ( maxlessica )!. The car is light so not much strain on the tires. I would keep an eye on them, if you can affort it get new ones this spring. Maybe a used set of Mustang tires? I think they start to come apart internally, the bonding between the layers can start to fail. I've heard this before in the last few years.
I do have another set of tires for the track. They are Toyo Ra1's, which are absolutely fantastic on the track. They have so much grip when they are hot. However, they are almost bald and I don't think the the tires will past the technical inspection required for me to be allowed on the track.
I am willing to look for tires that are suitable for the road and the track, but I don't see any tires that I would be happy to put $1000 towards. I don't want to spend much money. My car gets driven about 6000km a year (rain or shine) and I like to take it to the track a couple of times a year. Most competition tires will be great for the track, but it will have a short life, it will be noisy on the road, it will have a high cost and I may not feel safe driving it in the rain. Any tire that can perform well in the wet will not be as good on the track. I like the Toyo Ra1's, but they have been discontinued. The replacement for them isn't as good.
I've kept an eye out for used tires on the internet, but good deals on the right tires are rare.
