I've been a happy 2005 Colorado owner for several days now and just drove it in the rain for the first time yesterday. I have to say I was pretty disappointed in the amount of traction it got and am wondering if it's normal. I didn't have any problems with fishtailing on turns or stopping, but every time I would start from a stop my wheels would start spinning. It did it both on level ground and of course going uphill as well. It has a fairly new set of Cooper Discoverer HTs and is the LS model ext cab with the standard suspension I believe. Is this normal for these trucks?
