I am trying to long distance advise my mother-in-law on tires to get my late father-in-law’s 46 Chevy pickup yard drivable again (and on the road some day).
I believe the truck is a late 46 ½-ton, VIN is 6DPC8###.
Currently, I believe it has 8.55-15 tires on what I assume are the original 6-lug wheels. I think the original tires may have been 6.70-15, but the tire spec I found for the 15” wheel options on a 46 ½-ton did not list the complete size (only 15” 6-ply).
Am I correct that these wheels are “split rim” or ‘lock ring” type? Her regular tire dealer does agricultural and truck tires so this may not be an issue.
Would 215/75r15 radials work? That seemed to be the closest widely available radial tire. Inexpensive SUV type passenger tires in that size have a load rating well exceeding the gross vehicle weight. They would be little bit smaller diameter than what is on now, but I wasn’t sure if a 225/75/15 or 235/75/15 would be too wide for the rims.
Finally, would I still need tubes in these wheels with radials?
