So I have the ExtremeContact Sport02, and according to a test by TireRack, they are a better overall performance tire than the PS4S (at least that is what I recall), and I have driven it is >20 degree temps and no cracking that I have noticed.
Just something to think about if you are looking...
Like Chitown, I went from 19's to 20's and I like the ride better now. I went with 275/35 and 305/35, but I sill have a bigger side wall that my OE 255/40's.
So lookat it this way..
Stock................................. Replacements
Diameter - 27 inches........ 28.4 inches
Sidewall hight - 102 mm....106 75 mm
Even thought my aspect ratio went down I have more sidewall and more ground clearance than stock, not so much that notice, but some.
@24CTDH , if you don't need the well known name brands, SVE and Apex seem to be the main name brands listed here, I bought 20x10 / 20x11 Flow Formed Stance SF10s and I love them. While I haven't actually weighted them, but with the 275/35 R20s on the front, they "felt" lighter and the stock...
