Have 2021 jeepster edition. Has stock 235/45 R19s, which are garbage for anything other than highway driving. Street tread only and the highest ply available is 5. can anybody tell me what size rims and tires i can replace them with without having to do modifications to the wheel well. I would like to put some tires with grip on them. i live down an unpaved road in a hilly area, plus we get snow in winter. street tread are useless for grip, and 4x4 is useless without grip.. please help..
