I bought my 2004 rx8 a few months ago, and had to get my rear two tires replaced because they were bald from the previous owner. I don't really have the money to replace all four, so I chose to replace the back two. I had them replaced with the same tires as the front (the front two are fairly worn, 40% tread) and immediately after, whenever I took a corner with any speed the front two tires would slide out. I took it back to the tire shop after a few days of this and they showed me my front tires were wearing uneven (nearly bald on the inside) so i took it to get an alignment. It handles a little better but whenever i take corners with moderate speed they continue to slide out, which they never did before I replaced the rear two tires. Is this happening because of the inside wear and not because of the alignment? My biggest issue is I don't understand why replacing the back two would cause such a sudden change in the drive and such a fast wear on the front tires if they are the exact same tire, just a little more tread, and why it continues to do this after an alignment. Any help would be appreciated.

 

if your front tires are nearly bald on the inside, its time to change them.

you first drove the car with pretty much bald tires all around. because you now have so much more grip in the rear now its causing your front to slide since its not able to grip as well.

 

every time you drive the car your tire gone through a heating cycle and after a while the rubber on the tire harden and when the rubber harden the grip go down.
