Anybody knows a good tire source where I can find out all the specs of certain tires? I use tirerack.com and discounttiredirect.com but neither of these website mention the weight of the tires and the sidewall specs which I consider to be very important factors.

 

The tire manufacturer.

 

Not sure about sidewall specs, but tirerack does list the weight of the tire under specifications. Look again!

 

for a lot of that info, you can go directly to the tire mfr's website. Nitto, Toyo, and etc all have all of the sizes, dimensions, and weights listed..

what info about the sidewall are you looking for?
