Question:
I have a 2015 AIrstream Sport model travel trailer. I need to replace my OME Goodyear Marathon ST225/75R15 tires. What would be an equivalent tire today, or do they still make this model today? Thanks!

Hey Lee! Goodyear Marathon tires were discontinued and replaced by the Endurance tires. These are available but we only have them as part of a wheel and tire combo # GY97QB and # LH33FR.
If USA made tires are something that is important to you I would look around and see if you can find just the tire. I'm guessing you don't want to swap out the wheels, and they're probably pretty specific to the look of your Airstream. If you're fine with tires that aren't made in the USA you can use the Karrier ST225/75R15 Radial Trailer Tire # KE43KV as a replacement.
What trips are you planning this season with your Airstream?
