Howdy, just wondering on my recently purchased 2000 Civic 4 door sedan 77,000 miles, dealer put new Dunlop SP20FE P185 65R14 tires on it. They seem a bit thin so I was wondering if the rims will take a larger/wider tire, not low profile ones? Also, I'm assuming there is a hidden antennae with an amplifier as the radio reception is quite good? Oh, another thing, I noticed that it's fairly easy to spin the tires from a stop, my concern is how this car will do in the snow? Seems fairly light. Thanks...
