Hey I purchased the 21" wheel for the Vaquero from Roaring Toyz. I notice a lot of wheel wobble at hwy speeds of over 70mph. I emailed Robert at roaring toyz, and he said it sounds like the tire needs to be re-balanced. I have the counter balanced beads in the front wheel, I have used these before and never had a problem. I need to know if anyone else has this set up, and if so, did you have any issues like this, and if so how did you correct it. Thanks.
