Taller Tire and Wheel Recommendation for Size 20.5x8x10 with 5 Lug Bolt Pattern

Question:

I have a 1986 jayco cardinal and was looking to upgrade 4 wheels and tires to a little bit larger diameter wheel and tire. Its a 5x4.5 pattern. Original tires are 20.5x8x10. I think i can go 2” larger total diameter. Thank you

Since the overall diameter of the size you have now of 20.5x8x10 is 20.5 inches and you want to go to a size that is 2 inches taller the best size will be the 5.30-12 on a wheel with correct bolt pattern like the Taskmaster part # TA26RR which has a bias tire but a higher speed rating of 81 mph. This has an outer diameter of 21.5 inches. The next size up is around 24 inches which would be too much.
