Tire replacement questions for 19’ International

[stream19]

I know there are many posts regarding tires, I’ve read many, many and honestly am more confused than ever. We own a 2015 19’ International (which we love) with the original 15” GYM tires, my wife and I are preparing for a 2 month adventure through the Canadian Rockies then home to New England through the southern states.

I realize from the Forums how importance of good tires particularly with a single axle. I am planning to replace my tires, add metal stems, and tpms. I was set to replace with new 16” Sendel wheels and Michelin LT tires but now am learning about the advisability of staying with ST tires and the new Goodyear Endurance 15” ST tire as a quality option.

My questions is it better to stay with a 15” ST tires, if available?
Experience and/or opinion regarding the quality of the Goodyear Endurance tire?
Should the spare be replaced considering it has no miles and no sun exposure.

Thank you for any advice.

We just brought home a new to us 2011 FC19 and it needs one thing only-new tires. I plan to install GYE same as I put on our 25' Excella.

FYIW This trailer still has the original GYM tires on it and the owner said he had no problems with them.

Good call on replacing !

We went with 16" Sendels and Michelin LTX (E) for our 28'. Airstream uses the Michelins on the Tommy B models.

People seem to like the new GYE tires. I am partial to the LT tires.
