Hello there. I am doing a bit of self study research about road racing tires.
Do laptimes get slower as the road racing tire wears? Also is there a site where I can download a pdf of laptimes for an entire road race? Thank you very much for reading.

That's too broad of a question. It depends on the tire, if it's shaved, if it's a slick, and so on. You'd have to focus on one brand and model of tire to gain any true insight. I'm not sure looking at race lap times will tell you the complete story either as traffic will play a role in the results, but I guess it could be useful. Most everyone uses AMB transponders and the laps are recorded on www.mylaps.com. I've never tried to log in as a non-transponder owner so not sure if you can view them or not.
Usually tires go through heat cycles, and how many heat cycles a tire has, determines it's usefulness (and therefore, lap times). I'm familiar with the Toyo Proxess for Spec Miata, and I can tell you they were most effective in their 3rd or fourth heat cycle. For the most part, they didn't really drop off that much, but that had a lot to do with their compound. Some people even set track records on them when they were down to a few cords showing. It seemed like they had a second life on some tracks, but not others.
Thanks alot for the replies guys!

Which actually reminds me of another variable. The surface has a lot to do with wear rates as well.
