I should mention these came with our 47 Kit. & I highly doubt these are original. Had them inspected and these tires are unsafe due to them having cracks, and split with some rot found on them. So we need new tires

Here is a photo of 1 of the 2 Kits in our yard.. there you cans see the hubcaps that came with it.. Genuine Chinese Chrome..

Id like to go with very wide whites. Would that be 3.5 or 4 inch? With this size of tire as mentioned above? Or can I go with a higher size tire? This is the look We would like to achieve. (Not ours) but very nice tear. Does anyone know what size tires and Wheel is on this specific tear and is it 6 bolt or 5 by chance? looks like a California Atmosphere in the pic..

Any recommomendations?
Now the axle center sticks out about 3.5 inches from the rim.. What are my alternatives for rims and what can I do to find suitable hub caps. Tried baby moons but due to the center sticking out so far I came upon Coker Tire Hub Caps which are called (Bullet Cap Short) 3 1/2 inches.. it will fit but sure does look tacky. And it doesnt suite my taste.
Pic to assist with our question.
