Thunder Stock / V8 Warrior tire stagger

I am putting together a Thunderstock and have never raced on radial tires before.

The rules say that - “Tires must be DOT radial 70 series. All tires must be same size except right front. No recaps.”

I am wondering how much stagger I can possibly get when using the same size radial tires?

Are there any “tricks” for getting stagger with the radials?

yes get different brands I did it on asphalt

Thanks!
Do you know which brands tend to run small or large?

get 235 70 15 one cooper cobra for right rear and two futura’s for inside tires then you can run a 8 inch hooiser or a 10 on outside front
