I'm sure others will chime in on the proper tire to purchase, but if you ever want to go to a 235/85R16, you can lift your RV with these blocks. They are a Canadian company and sell kits for anywhere from 1" to 3" lift in 1/2" increments.
Trailer Lift Blocks
I've been looking at these. Aluminum blocks in 1.75 or 2.0 inch width. I don't consider the price offensive at $80-$90 a set.
What's odd is when you buy their "kit" that simply provides the 4 U-bolts necessary per axle, the price doubles. That's about $20 per U-bolt. Yes, they are grade 8, but seems excessive..
A 7500 lb axle U-bolt set U-bolt seems to run for about $8 on e-trailer....
