How will they run?
 

Thinking about getting some xxr 527's. I was thinking about getting the 18x9.75 +20 setup. But i was just wondering how those would run compared to the 18x8.75 +35.

wrong section to ask buddy

the only thing I can say is that since the 18x9.75 is both wider and lower offset than the other one, it will poke out much more.

the real answer to your question requires you to give us more information. What's your suspension setup, what tires do you plan on running...
