Trailer tire question

[Darrell]

I have to replace two tires on my flatbed trailer. Both the right-side tires went bad, are out of round, and one of the two has a tread separation. The two on the left side are fine. I think what happened is the two on the left were getting the evening sun for a few years. 

I'm going to go and get the two new tires today, but I wonder if makes sense to have one new and one used tire on each side, or to put both new tires on the right side. Maybe it makes no difference at all, the two on the left are not badly worn. Any informed opinions?

I guess I need to choose a better parking site for my trailers or get some of those tire covers. I really don't use my trailers often, but I need them from time to time.

I just put 2 on an enclosed and they are running on the rear axle. For me it makes sense to have a new one on each side

That's what I'd do. Put the 2 new on the rear axle, the old ones on the front.

I’d spread out the risk.

Thanks guys.  I took Fujimo's advice and put the two new tires on the rear axle and the two used ones up front. I've now spent about $600 over the past week on trailer tires, none of which were worn out, all of which had aged out. The two I just replaced were about 5 years old. The four on my dump trailer were original, I think, so I can't complain about those.

Were they all bought at the same time and how old are they? I'd probably put all four on, especially if you do any highway/interstate driving.

Check the date code on the other 2.  Trailer tires hardly ever wear out, they age out.

Don't purchase China tires. They are trash. All my blowouts, on my RV, have been from mostly new China tires. Goodyear are the best, but you know it when you pay for them. Put all 4 on.
