I use the one at http://www.dsm.org/tools/tiresize.htm whenever people start asking what tires can go on their car. Very handy tool.

I use this one:

In combo with this one:
http://www.rimsntires.com/specs.jsp

the first one is good for visualizing the details and numbers found on the second one.

recently i change my tires... i was using the oem size 195/65-15... and i change it for 195/50-15 i know its not a big change
but i have the dubt if i've made the right choice??? it does look a lot cooler but now im worry if the new tires can handle the weight of my car...
i know that the speedometer can change but that doesnt worry me at all...

That is a pretty big change...about 10% on the calculator. I can't imagine you would have any problems with them supporting the car, but the speedo and odo will be VERY off. About 6mph@60 and your odometer will say that you have put quite a few more miles on the car than you actually have. Not only that, but unless you lower the car too you are going to have a bit more than an inch of extra wheel well gap.
