Lightest wheel-tire combo?

The front wheel, tire and tube on my Crazy Cart weighs just under 5 lb total. The rear wheels are skateboard wheels and probably about as light as Mike's suitcase wheels. Since there are no springs it is all unsprung weight :D

Did a search and found the post Manik reference's here. It's 6 years old, so pricing is out of date, and the Caterham wheels have since changed, so not sure how those weights compare to their replacements.

Hold on - these latest weights from JohnCH and Manik are before tires right? Has to be because it seems so low.

 

My new BBS wheels are 8 pounds (assuming the 7 inch x 13" sizing). The larger 9x13 rear weighs in at 10 pounds. From other forums the Avon ZZR weighs in at 18 pounds front and 19 pounds rear so that gives an all in of 26 pounds front and 29 pounds rear.

 

If you switch "road" rubber out for slicks then that will save a lot of pounds as the race tire carcasses are much lighter - less robust construction.

 

Interestingly if you want to save unsprung weight then going low profile tires will work since the tires are generally heavier than the wheels. But sevens like a thicker tire profile for handling purposes....interesting dilemma.
