I just bought these rims for my 05 yukon in 20x9 10 offset and 5.400 backspace. That is what Americas discount tire said was correct. I was originally getting 285 50 20 tires but the ones I wanted were out of stock. They have it in a 305 50 20, will that work on stock suspension? My other question is with that setup will I still be in the fender wells?
