Got 2 quick questions

What is the optimal rear tire pressure I should have for a dyno run.

I have 285 35 18 in the back (don't ask why, someones mistake and my ignorance). Will having this wide size tire reduce my hp and tq numbers.

Thank you

Not by much although it is heavier (slightly). I'd run 35lbs and strap her down. Drop air only if it slips on the dyno and you need traction.

Actually in the past when we've had a car spin on the dyno we have increased the tire pressure.

In the OP's case he should be fine at stock pressure
