20X10.5 +25 Rear Tire Size?

[MrSlickk]

Wondering what tire size I would need to run in the rear with these specs 20X10.5 +25. I tried on a 305 and it wasnt flush stuck out too much.

Is it the tire or my offset?

Anything wider than a 275 might be an issue with rubbing with a +25 offset.

On my HRE's I had 10,5 +28 with a 285/30. There was about 1mm of clearace IF that! haha

It looked great, I saw you at speed district a few months back I was there with Matt. But anyway this is lowered on Super Sports but I'm thinking of giving the 285 a shot. Here's a pic of the 305

Your offset is way too aggressive for 10.5". You can run 275 without rubbing. For 10.5", you need ET33 to run 295 on a drop.

What would I need to run a 305?

Wait. Do you have an E9x or F8x? They're 2 different offsets.

LOL Your signature caught me off guard. What brand coilover are you running or plan to run?

[MrSlickk]

OK. If he's going to start from scratch on an ideal wheel setup, I'd recommend the following:

Wheels: 20x9.5 ET22 front and 20x11 ET40-42 rear - 255/30/20 front and 305/25/20 rear

Tires:
255/30/20 front and 305/25/20 rear (This setup will have the same rotation diameter front and rear - the F8x MDM likes the rear to be 2.6% larger - you'll need to code Euro MDM for less intervention)

-OR-

275/25/20 front and 305/25/20 rear (This setup will not have MDM intervention issue)
