I don't think a 295 should be mounted on a 8.5" wheel.
The diameter of the wheel does not limit the width of the tire. The width of the tire needs to be matched to the width of the wheel. A sidewall angle needs to be maintained to assure lateral traction (handling). It’s a matter of performance and safety. Pick a tire that you want and then look up the manufacturer's recommended wheel width for the tire width (255, 275, 295 etc.) that you want. Tire Rack has the data for each of the tires they sell.
