C4 cab tip came with Conti's. They are very noisy. Going to replace them soon. EPE recommended bridgstone S 03s. They certainly have a nice look anyway.

Most driving is highway speeds for long distances. Anybody got a tire they really feel good about?

 

I really like my S03's. I changed from Conti's also.
I went with new 8" rims in front and kept the 10" in the rear. Mounted 225/40x18 on fronts and 285/30x18 rears. (rear below)

I also replaced my stock contis with S03s (yesterday!), though I stayed with 265/35 for the rears. The ride home was the smoothest ride I've had in a long time in the car. So far so good. Tirerack gives them a good review - check out their website for comparisons of the most popular choices.

conti's pirelli & michellin all seem about the same, it helps some if you lower the rear tire pressure down to about 36-38psi.
