My back tires scrub the wheel well. They're 275s. Getting new 285s put on so im sure it'll be worse. Couldn't find any 1 or 2 inch spacers so I went and bought some 5/16 from advanced auto. Wondering if they'll fit or am I going to have to wait to find some thick studded spacers?

This depends on how bad they rub. You are going 10mm wider so 5mm more into the wheel well. A 5/16 spacer is 8mm. So you'll gain 3mm of space with the spacer and the 285. The other thing to consider is how much overall diameter will change with the new tire size. This will also be a factor depending on where in the wheel well curve its rubbing. As far as extended studs, you can just use ET lug nuts with a 5/16 spacer.
