Mismatched tires/tread wear

I have Nanco 7.00 15 LT 8ply tires on my dual axle 1961 Avion trailer. Last year I replaced one of these tires with a Super Cargo ST225/75R15. I'm wondering if this caused some axle balance issues since I'm not certain the tire size was exactly the same as the others. I towed my trailer like this for a few thousand miles and it seemed to cause the Nanco tires to wear faster. I'm buying a new set of tires this week but I still would like to understand the physics of mismatched tires better.

Thanks for any pointers.

The radial tire has less rolling resistance, and has a smaller diameter. It's not a good idea to mix and match radial and bias tires, as strange things happen, like differences in traction as well as tire wear.

Meddle not in the affairs of dragons, for you are crunchy, and taste good with ketchup.

Smoky, sorry about your tires. I have been reading soooooo many tire threads. I have about decided to go with the 700 x 15 bias ply tires due to the extensive damage that seems to occur when you have a blowout with radials. May I ask which tires you are going to buy? Are you going with the bias ply tires again, radials, and how did you come to your decision?
