Odd question, im thinking of picking these up for next year but im not sure if I want to sacrifice speed because I always thought those wheels are heavy. Can anyone with the 18inch rebels tune in and tell me what about they weigh with a tire?. I figure my firehawks with tire are like 50lbs or something, didn't weigh them but just a guess so I wanna know what the weight difference would be in switching from these to the rebels. Thanks
