Although built for 15" rims, the '64348' tires are only load range 'C' (and no increase in load capacity over the tires they make for 14" rims). Consider buying only the '64351' tires, which are a correctly fitting "upgrade" for an "older" TM with the lift kit installed. ("8-Ply", Load Range D.)

My own tires are the highly regarded Maxxis Load Range E (supporting up to 2830 pounds at 80 PSI). For comparison, here are my Maxxis specifications:

model: TL15713000
size: 225/75R15
'plys': 10
diameter: 28.3
section width: 8.9
Max PSI: 80
Max load: 2830
Measuring Rim width: 6
Tread: 9/32

"Loaded Radius" is irrelevant to rubbing against the TM wheel well. What matters is the total diameter, and it's 28.3 inches (same as mine). It's sized to fit a rim of "6.0" width, which is also correct. The Section width is 8.8", slightly less than mine. (That will work fine).

Are the tires "good"? I have no idea. But the dimensions are correct for doing the 14" -> 15" upgrade.
