Motor trend boys hit 177 on Autobahn...

 

Not that 4 mph more matters, but where did you read that? I just re-read the Motor Trend article and here is the quote from the SRT's visit to the Autobahn:

"We see an indicated 157 mph on one stretch, storming past BMWs and Benzes, and canter along at 120 mph or so where we can."

They hit 173 mph on a straight in Italy.

 

Seems like I ran across a thread where someone put 315's on the back, but on different rims obviously. It may require a different offset to get them on there. If I run across the thread I'll hook you up woth the URL.

 

Thanks for all the responses.

I'm sure there is bigger tires with adequate speed ratings such as those designed for Vipers, Vettes, Porches, Ferraris, Lambos, Bugatti and the likes.

Just trying to get an idea - would like to hear about the person with the 315s.

 

With the price of Goodyear Supercar Tires.....I'll stay with the original size...would have to take out a loan for larger size. Plus the SRT looks nice just the way it is.....(just my 2 cents worth)
