My '48 Chevy 1/2 truck currently runs on a set of 10 year old radial tires that have 7500 miles on them. Truck is housed in a pole barn and sees no winter salt. I wonder if I should consider replacing them due to their age.

If yes...I want to use a quality blackwall radial tire with a bias ply look and maintain the old school "tall/skinny" look as original. Wheels are 15" X 6" from the Wheelsmith. Rear end is still 4.11. I have a side mount spare tire that I would replace as well. Is there a recommended tire size AND recommended manufacturer/vendor to accomplish all of this?

I have truly valued the input from knowledgable members on this forum since 2009.

Thank you.
