Towing our 28’ Jayco

X2, whether this is the issue you are experiencing or not, every time we put new rubber on our tow vehicle it made towing a bit squirrelly for the first 1K miles or so. Our truck is dedicated to towing our 10K TT, if your tow vehicle is a daily driver put some miles on your new treads, make sure they are aired up properly and your WD hitch is correctly adjusted. A slightly bigger, firmer tire should tow fine, we went bigger on our truck tires and they performed great after we were able to get some wear on them as the rubber was much harder than previous tires being that they were rated for more weight and significantly more mileage.
