In shopping for tires for my '67 Shasta Astroflyte I've found that there seem to be very few good choices in brands of tires. From what I understand, the top 3 are (in no certain order) Goodyear Marathon, Duro & Maxxis. I don't know what which brand I will be getting.
I bought the trailer with P195/75R14 tires. Obviously I need to get ST rated tires. The old "P" tires did manage to hold up for a 60 mile trek from where I bought it at mostly 50-55mph, 60mph max (State/US highways.
ST205/75R14 is the correct tire size for the trailer. However, Goodyear also makes a ST215/75R14 tire. I was wondering if I should put larger tires on it if it'll fit into the wheel well properly without hitting the wheel well on a hard bump. A size 215 tire rated C gives 110lb more capacity than a 205 size tire also rated C: 205/75R14=1760lbs vs 215/75R14=1870lbs, according to TireRack:
