454 SS wheels and tire setup

[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
17x8 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.

You may want to look at ForgeStar wheels. They are in the same price range as the ESR wheels above but offer up to 12" wide.

I currently run a 295/45/18 on 9.5" wheels with similar whp numbers on my 2000. I have been thinking of having the rears rehooped and running a wider tire out back but am having a hard time finding a 28.5-29" tall tire in a wider width. I haven't found much of anything in 18's wider than the 295 that are taller than 26ish inches. However, I am trying to stay with a 200+ treadwear tire for class rules. I believe there are more options if you are ok with a lower tw or competition tire. 19 & 20 inch seem to have more tall/wide performance tire options that have a decent weight rating (I presume we can thank the more portly modern pony cars for this).

Having the exact same problem. I've been considering going to a 19 or 20 on the rear but I want sure if I could find a tire that would work well with such a small sidewall.
