I've included a picture of the tires that are on my 89 coleman columbia camper. They are "hiway master" brand (this is what was on them when I bought them). I am in disbelief that these tiny tires can take my camper on hours and hours of driving. Are all pop camper tires so small? Is there no need to worry? If anyone has any advice on better or bigger tires that I should be using please feel free to let me know. I know this may sound like a ridiculous question but I know next to nothing about this. I'm about to take my camper on it's first road trip and we will be driving for about 10 hours round trip. I'm nervous...I did just have my bearings repacked though which makes me feel half decent.
