Tire Size Opinions

A tunnel ram comes on 35 4000

I hear this all the time, the reality is this thing is screaming mad from go, I don't even have full throttle yet, just made a new throttle set up and need to bend the gas pedal a little, plus just fixed a fuel pressure issue, I'm just barely getting to 3500/4000.

I did a burnout for the first time in ages, due to said fuel pressure issue choking the life out of the fun pedal, and I could have easily roasted the tires down to the rims.

That reminds me, I need tires, any suggestions on sizes?
