Will a 245/55/18 tire fit on the stock 18s? I think it will only throw the speedo off by .04 mph. I think this car should have wider tires to go with all that torque. Thanks in advance.
Crest? Do you mean distort? You would have to be at VERY high speeds for modern radials to do that, especially this size which would not distort any more than stock since the width increase is so small.Michael said:
Very likely not...especially with that short a sidewall...that and I would not like the stresses put on a tire's sidewall that would be more in the 60 range and that wide.E55 KEV said:Don't think a 265 width will fit on a 7.5" width rim. 255 may be max.
I agree. The stock ratios are correct for cornering, braking and acceleration. The Conti self seal is not my tire of choice, though. I will be going to a better tire come spring.II kings 9:20 said:Well guys, ideally for cornering, sidewall flex regardless of profile you want to maintain a high rim width to tire ratio (.85 or better no definite rules) used in racing and street. e.g. stock 225 is 8.858". a 7.5" wheel/8.858=0.84 in other words 84%, not bad. A 255 on stock wheels gives a ratio of only 74% kind of like running in a shoe that is too big with your foot flopping around. Imagine a 225 on an 8" wheel, 90.3%, outstanding, quick crisp reflexes. The new Mustang has a ratio of 86% and Acura TSX 82% for comparison.

Eighteen-inch four-wheel disc brakes (so called because they are designed to fit inside 18-inch wheels) are standard on Chrysler 300 Hemi C and all international models, and optional on other models. They feature twin-piston aluminum calipers (1) and vented rotors (2) in the front and single-piston aluminum calipers (4) with vented rotors (3) in the rear. Although the rear calipers appear the same as the 17-inch system, the rear calipers used with this system feature a wider jaw to compensate for the wider, vented brake rotors used. The calipers with the 18-inch system, which are readily visible through the aluminum wheels, have a gray anodized coating for corrosion protection and long-term neat appearance. Although the caliper used is the same, rear-wheel drive models mount the front caliper to the front of the knuckle while all-wheel drive models mount the front caliper to the rear of the knuckle.
