So I bought my certified pre owned 2015 rcf back in september last year, it was in garage all winter so I have only put 5k miles on it, I'm pretty sure I already need new tires. Anyone know what the stock tires are rated for? I didnt check but I am sure when I got it they left the original tires on it, honestly its had no traction since day 1 so I'm curious how long I've needed tires. I'm not familiar with the tread so I'll post pics, honestly the tread is like 3x deeper in front than rear...pics are rear then fronts.

 

Many many threads on tires in this forum. Do a search and you'll find them.

Here are two recent ones:

I would replace them. Get the MPS4S. Looks like your rears have 3/32 left and front seems to have a good 6/32 left. I have 9,000 miles and my rears are at 5/32 and fronts are at 6/32. I have about 4000 - 6000 miles more left on these tires.

 

Should I measure? And should I just get tears since fronts still okay?

 

Your rears are worn out. No point in measuring those. For high performance sports car, generally recommended to switch all four tires together for predictable and consistent handling. However, you can probably get by with switching just the rears.
