Can anybody give me any insight between these two tires. Cost roughly about the same. But which one is better overall in bad weather??

 

Proxes 4 hands down. They're a little better in the snow, a lot better in the wet, and WAY better in the dry.

The P6 4 Seasons will last longer, though.

 

My wifes 04 SAAB 93 came with the P6s. The P6s drove ok but I was very disapointed in the wear, 26K and the tread was chunking off. I normally don't care about tire life and enjoy getting new ones, however the SAAB is a lease. My wife was complaining about the lack traction, that's what made me give the tires a close look. The cars now on Goodyear F1 GS-D3s and the wife is very happy with the restored performance.

BTW the P6s were OE on some BMW 3 series and the chunking condition looks to be more wide spread than just my car. I've found 2 other sets that look the same in the tire pile at work.

 

I loved my Proxes 4. They are all worn out now, only got 18000 miles on them, but the roads are horrible here, I am a bit spirreted at times, and about 1000 miles total was on misaligned suspension (due to workin on crap and not having time to get it realigned and what not). So I guess they faired ok.
