Just wondering if anyone is running 275/50/20 tires? Looks like most people run 275/55/20 but they are significantly larger and with the Pentastar motor being such a dog on the freeway, I'm trying not to make that worse. The 275/50 are only slightly larger and wider than the stock 265's but it seems like options aren't at vast. The stock Goodyears are starting to crack with only 32k miles so I think it is a good time to look at different tires options. These would be going on 2015 Altitude. Any help would be great.
