i'm looking at some 15.5 lbs . is that less than the stock rims? how much do they weigh? does anyone know of some rims that go with the square theme of the Xb?

 

The stock tire and wheel together weigh about 32 lbs, I believe. Don't forget to factor in the rubber you're gonna run since that will be different than the stock as well...

Theoretically, it should reduce the amount of mass you have to get rolling from start, but don't expect any really noticeable gains. Lighter wheels will also reduce your unsprung weight helping the car to handle a little better. Again, the gains may be negligible but every little bit helps... and surely helps more than strapping some heavy ___ wheels to the Box. BTW, mine only weigh 14 lbs - haha.

And I would recommend NOT getting square wheels, stick with round ones...

 

yea, I threw out the square rim idea when I realized what it would do to my MPG. haha
