I was just looking at some Youtube stuff about Hunter Wheel Balancing and they make sure the tire pressure is correct before the balancing process starts. With my new tires I've no clue what would be a suitable pressure for front and rear for my particular car. Would it be advisable to note what pressure is on the existing tires and go from there ? Vredestein Sprotrac 5 in this case. I'm not trying to split hairs here, just trying to get it right. Ideas ? Thanks.

I think my car IM suggests 22-24 & 32 rear. I run 22/32 and I balance them with those wind pressures.
Don't remember if you're running 195/60's or 195/65's- if 195/60's, they hold about the same air volume as a typical 165R-15 so I would start with 28 or 30 lbs in the back, 22-24 in the front and see how it rides. If you have 195/65's, they hold approx 10% more volume so you could lower pressures accordingly. Even if you end up changing pressures by a 2-3 lbs after they are balanced I can't see that being a problem.
I agree, a few pounds won't make much of a difference. You just don't want either way low or way high, such as 10 pounds or 40. As long as you are in the ballpark of what you normally run, you'll be OK.
So, does this mean when you rotate the tires and change the pressure by maybe 10 psi you should re-balance them?
I put the Michelin Premier tires from Costco on. I have been driving them at 20 front and 22 rear. I just moved them to 24 / 26 and have not noticed a difference in ride or grip. I very much like the tires and I have the same ones on my Camry which weighs twice as much.
