Our american racer bias plies are 6 lbs each, running on diamond racing 13x8s, the wheels are a bit over twice heavier than the tire.

which AR 13" tires are you using? and in which compound? I'm seriously looking at these as an autocross tire.

Will be running Hoosiers, just not sure if I will be running cantilever bias ply or radials. Plan on running the 80 compound. I need to give Hoosier a call and chat whit them before I decide on a tire. I am budget limited so I can't purchase both and test back to back; though it would be nice.

I'll have to weigh my cooper 13" radial slicks but I'm pretty sure they are in the 10lb or so range...bias plys are light though

As for 13s the JB wheels should be good...the only issue I have with my 13s is the heat at times...so compound is important...not as much circumference so the tire builds heat quick. And the wheels I run (Keizers) don't do much for cooling...but that's what my brake ductwork is for
