I'm still running the stock tires that came with the car, and they are all ready starting to wear down significantly in the front and rear (I've had to drive them in the snow a few times). What do you guys and gals recommend I get as my next set of All Season tires for my MS3, with the same sized rims that come with the car?

I've been looking at these:
Pirelli Nero M+S (All-season)
Bridgestone Blizzak (winter tire)

Anything else??

 

if your gonna have a set for winter and a set for summer...go with the azienas RT-615's for summer tires and the blizzacks for winter, dont get an allseason tire for summer driving if you have a second set to use...and i say the azienas because unless your going to do track days at the car the bridgstone is a waste of money the azienas are so much cheaper and for DD and some AutoX events they are the same or better than the RE050's the only advantage the RE's have over the 615's is when the get really hot they perform better, but you wont need that unless your going to track it, and the 615 will last longer

 

That's good advice ^ ^ ^ and overall, I was happy w/my Falken's too. For the $$$ they were a good buy, imo
If you are still considering an All-Seasonconsider the new Falken ZE-912. CU recently rated them a best buy in the All-Season HP/UHP category, and they are supposed to wear better than the 512 series also.

 

after how long is a good time to change the tires? how bout rotations?

 

consult the owners manual

 

Falken Azenis are a good quality summer tire for a reasonable price. i use them in the warm season for my 3s as well as for auto-x. if you want all-season tires, a good comprimise between performance/ride quality/durability is BFG Traction T/A. i use these during the cold season and throughout the winter and they handle pretty well in the snow. ive also autocrossed with the t/a's and they handle pretty well.

 

I talked to the Mazdaspeed specialist at my local car dealership, and he recommended one of the tires I was looking at, the Bridgestone Blizzak LM-22! I'm going to continue looking around, but I do believe I'll be getting the Blizzaks!
