Leaving sticky residue on the carpet is considered "damage" to the field which may cause issues at your events. Everything in our experience is pointing at the wheel choice as being the issue. However, there are several other problems that exhibit the same symptoms. The tape will eliminate the most obvious. If your problems continue then there is likely another issue(s). Don't you have a local team that can come and give you guidance?
Yes, we do. We have been working with team 1241 throughout the season but were never able to see this problem since we didnt test on carpet until we visited 610 a couple days before stop build. That was when we had this problem coming up. I know this must be a problem in the wheels since it does have alot of friction. We could see the speed difference while driving on the carpet. Since changing the wheels is very difficult this late in the season especially since our robot is bagged up and we don't have a practice bot. We have duct taped our front and rear wheels which did seem to help out a bit. I think that our biggest mistake was swapping the air tubes for pool noodles as mentioned before in the tread. Right now our team is throwing ideas out to see what we could possibly do at our first regional in 2 weeks but this weekend we are going down to 1241 and making extra parts as well as some guidance
