I've been reading a lot about tires here and online. I'm wondering what folks in these types of climates are using for their replacement schedule. I was thinking I may do every 4 years based off what I read, but wanted feedback from others. A lot of folks mention the conditions you store them in. Being in Arizona, dry rot for tires is a big concern. My PUP is stored in our garage away from all elements but heat and dry air. I do not have tire covers for when we are out camping though. I also check pressure and visually inspect both tires and the spare before we leave each trip. Thanks!
