SAE Baja Competition-lightest tire/wheel combo

[eshook350]

I am on a senior design team this year for the SAE mini Baja competition. I was wondering if any of you guys have ever come across a list of weights for different tires and wheels. I am looking for the lightest combination of a 22 in tire with a rim and still hold up during a rock crawl and a 4 hour endurance race. Price is not really an issue since this is a competition; I am interested only in the lightest weight possible. I am looking at some type of knobbly tire, unless there is some other pattern out there that is lighter. We will be running a MX type track for the endurance race with a few small, mud holes. The car is also restricted by a 10 hp Briggs; just something to keep in mind.

 

Thanks for your input
