Well I think it's not going to snow anymore in MD so I decided to switch out the tires on the 86.5 928S. Back in the fall I bought 4 new Blizzak tires and rims so I would not die in the snow. They're on 16 inch pie plate rims and are 225/60R16 tires.
They make... noises. First, they *fill* the wheel wells, to the point that when I come into the driveway and go over the little hump while turning I can hear the rear tire rub slightly against the wheel fender. More importantly, the front tires will just barely rub against the plastic brake ducts when making a tight turn in a parking lot. This is not due to wheel turning stops as trying to steer without making the noise leads to wide turns that are far greater than any other car I have ever owned. Not a big deal, I lifted the front back up to the low end of factory settings and I can probably drop 10 pounds of pressure on the tires to make them a bit smaller.
However my car is weird: The Previous Owner did a lot of odd stuff with it (insane lowering, etc) and one of the odd things is it has Continentals 225/50ZR16 tires front and back. Also the rear two rims are different from the front rims, they are a bit wider but have the same size tires as the front.
The tires.
Difference between the rear tire rims and the normal 16 inch rear rims:
When I got the car I just put on new tires of the same size and enjoyed it. Now the "summer" tires are shot, and I need to replace them.
Question: What do I replace them with? Do I go with the 50's all around? 60's? Should I be using a wider tire on the rear if I have the wider rims? It's an 86.5 so it has the 87 and up suspension and that might include different brake ducts (maybe they did them different in 86.5 due to the difference in brake discs and the like, I don't know.) The rear wheels do have spacers behind the tires, and they look to be factory.
Thanks!
