I was looking at a set of used slipstreams that are 17x7.5 all around
If I get those, I plan to get 225/45/17 and 255/40/17
That wouldn't be too bad right?

What tire pressure should I use?
Would I need centering rings?

TIA,
Somang

 

Depends on the tire. A true 225 no sweat. But the Bridgestones would be pushing it. 7.5 will work in the back, but be sure that it has a strong sidewall. The pressure will be easy, run stock and do a quick run, the wear line on the side wall will tell you how much to add or drop 2 psi at a time.

Rotas work fine, despite their detractors, but look carefully for fine cracks around the hub. I have no idea about the rings, but the front hub is much smaller than the rear in our car.

 

What tires would you recommend?

I was considering RE750, RE050A PP, or BFG KDW2

What do you intend to do with it?

 

Street use
Do you think about 32psi all around would be fine?

 

I would not put 255/40's on a 7.5" wide wheel.
I'd probably go 215/45-17 front, 245/40-17 rear.
Even a 245/40 is pushing it. Recommended minimum width for a 245/40 is 8". Recommended minimum width for a 255/40 is 8.5".

Actually, I'd probably only consider rear wheels at least 8" wide.

 

A 225/45/17 RE 050A or RE 01R is about as big as I'd go on a 7.5" I wouldn't want to run a 255 on the highway on those for sure.

 

But don't people run 255 on stock wheels?
Our stock wheels are 7.5" on the rear
so what's the difference?

 

The AP2 rears are 8.5" stock
7" in the front
