15x8 rims advice please
So I have a 1970 oldsmobile delta 88 custom and I bought some American racing torque thrust 2 rims 15x8 and im trying to figure out a good tire size for the front and rear id like the rears to be a lil wider with it being sort of a muscle car, it has a 455 cu in motor with a 2brl carb any suggestions or advice on what tire I should get I only found a few things on the internet that said 205-50-15 and 205-60-15 would fit but would wear down quickly.

I have no idea what width will fit into the wheel wells, but I have used 225-70, 235-60, 245-60, and 255-60 on 15x7 wheels on my Cutlass. I have never heard of the sizes you posted.
A key factor on what will fit is the wheel backspacing. If you post that, folks will have more info on tire size recommendations.

I use 245-60-R15 all around on my '72 Cutlass ragtop's AR Torq Thrust 15x8's (4.5" backspace on the wheels). For a little wider stance out back, I have 1" aluminum spacers mounted to the rear drums, which give the rear wheels a slight staggered look. Benefit is all 4 wheels can be rotated front to back without issue and can carry a matching spare in the trunk. No fitment issues for this size tire on these wheels.
Not sure how yours would clear given the more narrow backspace you have to work with but possibly no issue given the depth of your wheel wells

I have a 1966 Starfire (full size 88 model) with tires with very close in diameter to my original 8.25-14 are 255-60-15 in the rear and 225-70-15 in the front. They are Mickey Thompson Sportsman S/T. Your car should be very similar. Here is a picture.

The most important factor in choosing tires for ANY car is to ensure the tires have the load capacity to support the car safely.
The original tires on your car are H78-15. These have UTQG (a numerical rating of the load capacity) of 100. This is equivalent to load capacity of 1764 pounds.
The tire you posted, 205/60-15, has UTQG of 91 which equals load capacity of 1356 pounds. This would be dangerous to install on your vehicle. No tire shop would install this tire on your car.
For each tire size you consider, look up the UTQG or load capacity in pounds to make sure the tire will support your vehicle in safety.
