I suspect that if you are running summer tires with temps in the 40s, you're getting LOTS of wheel spin, slip, and otherwise dangerous driving situations. Below 50 or so, summer tires start to get hard and lose their traction. If temps get below 40 you really ought to park it unless you get winter tires. Driving would not be fun in those temps with summer tires, not counting being dangerous. You might consider getting a set of used wheels and winter tires if you are going to drive it during cold temps. Adjusting the pressure within any reasonable set of specs won't help. I went with a set of used wheels and Dunlop Winter Sport tires for winter and I've been getting around just fine in below freezing temps and snow. Do not try that with summer tires. You'll regret it. However, with winter tires... tons of fun! This thing gets around great! Just be sure to get rid of those summer tires and put on a good set of winters. Just fyi
