Greetings!
I recently purchased a 4*8 Harbor Freight trailer [url=(this guy)]http://www.harborfreight.com/1195-lb-capacity-48-inch-x-96-inch-heavy-duty-foldable-utility-trailer-with-12-inch-wheels-90154.html[/url] for the purpose of building a lightweight foam and fiberglass pop-up style foamie. The goal is to keep it incredibly lightweight as I'll be towing it behind my 2008 Mazda3 5 door which is supposed to be able to tow somewhere between 0 and 1000lbs depending on the manual you read.
I noticed that the tires are smaller than a normal car tire and have a sticker on them saying they're rated for 50mph.
50 is quite slow, far slower than my preferred speed while driving out to a campsite. With that in mind, my questions:
1. Will these tires be perfectly fine at higher speeds considering the fully loaded trailer will be under 800lbs, preferrably under 600lbs? If not, where should I be going to get new wheels and tires?
2. The trailer sits relatively high with the leaf springs holding it up. Would it be a worthwhile purchase to get some torsion axles with the goal of making the bed of the trailer sit lower?
