I am pretty sure I am the first one to have these wheels. :) I borrowed a 255/45/20 Goodyear F1 tire to test fit. With the front tire in the air had about 1/4" clearance from the tire to upper arm. On the ground the tire just touches the arm. I am not a fan of spacers or grinding so I will probably go with a 245/45 on the front. The rear has plenty of room. Do you think I should go conservative with the Goodyear Eagle RSA 245/45's all the way around or go with maybe a 275/40 for the rear? The problem is as far as I know Goodyear does not make the 275/40. I would like to have the same tire type. Any suggestions? I will post better pictures when I have the new tires.

Why would there be any touch, your OD is only 0.4" larger than stock, there are guys running 22s with a larger OD and no touch. Have you measured the actual OD, the stock OD calculates to 28.6".

The OD is not the problem. It is the tire width due to the wheel offset. I probably should have been more clear in my first post on the contact area. The wheels are marked 20x9JA 25.5. I assume 25.5 is the offset.

I think JA is the offset. Probably too positive, which is odd. I'd think it'd be more negative to give more room for the bigger brakes. Maybe the spindle/control arm is diff. on the 300c.

Looks good, but I'd lower it (just like I would w/the SRT-8) w/some Eibachs.

I decided to go with the Eagle RSA 245/45/20 all they way around....this time. Depending on how they look and wear, I might switch to a wider rear tire in the future. Should have them on by Tuesday and will post more photos then.

Tire Pressure?

Hey you lucky guys with the SRT8s:

Can you please check your owners manual or driver's door for the recomended tire pressure? I am getting my wheels mounted today. Thank you.
