Wheel/Tire options 1990 454 SS

[454SSguy]

Alright guys need some advice on wheel/tire setup. Truck is 1990 454SS that is mini tubbed with 4 link so I can run a pretty big tire in the back. Truck is toy/cruiser that I would like to AutoX.

Has 498CI bbc on E85 makes ~600-650rwhp
T56 trans, 3.73 gears with an eaton trutrac

Currently run
17x9 with Nitto nt450 275/50r17 in front

17x11.5 and Toyo Proxes tq 345/40r17 in rear

Wheels are STEEL cragar 397s that I had widened. They are ridiculously heavy.

I want to go to something lighter but it's hard to find something in the right BP without getting something custom which is out of my price range.

I found some wheels I like from ESR but the widest I could get is 18x10 or 19x10.5. Should I get something else to keep the wider tire or does someone make a tire that will work with my power/weight levels on a 10" wheel?

If anyone has any input on a similar looking wheel please let me know.
