255/70/15 are what is run around here. Wouldn't work for you, not enough gear. At our 3/10 I run a 3.08 gear with a t-350 and turn 6200-6400

What are the tire rules? Do you have a spec tire you must run? Can you run off sets? 15x8 or 15 x 7 rims? Can you sipe or groove tires?

your gonna want to go pretty short on the roll unless you don't want to turn to many rpm's back when we ran a 1/4 with a 3.08 and a t-350 in 2nd we ran 74-75 and turned around 6500 i woulkdn't look at anything taller than a 78 in roll

if your on 15x8 wheels you'll have a pretty hard time finding anything that will work without changing your gears if you want to run 14x7 wheels you could try 205/70/14's thats what i run they come out to be around a 78 in roll i have akso ran 195/75/14's came out to be 76 in roll

i'm still looking can't find any with 4 3/4 bolt pattern all i have ever seen are for 4 bolt mini stocks i usually use white spokes. you might want to look into finding a 3.73 gear then you can run bigger tires on the rear

I think that is the way I'm leaning. Thanks!
