I'll try to get some pics over the weekend. It's all pretty simple stuff.
215s clear fine and have worked well for around 6k miles. Decent radials are a lot wider, taller and beefier than cheap s**t originals. They are visibly more than one size up. I'd recommend them to everyone who spends significant time on the road. Counter guy and I would have gone 225's but DW was reluctant and standing right behind me.
215s have done the trick so we're both happy.
Be interested to hear about your axle. Ours was bent from the factory. 4k miles in, on an east coast to SW trip tread on both tires was cupped on both edges and big bubbles in the sidewalls. We were lucky. We dodged a bullet and got to a great old school alignment shop in Denver. It's Merrill Axle and Wheel. They were wonderful, straightened the axle, new tires mounted and balanced (originals were not balanced either) and on our way the same day.
FWIW, FR RV dealer in Denver wouldn't touch it as a warranty repair since they didn't sell FR WW line. Interesting segmentation and not at all what salesman touted when we were buying. Service guy sent us to Merrill so it all came out well in the end but cost us about $450.
