Just got a set of rocket wheels for my hydro WB and love the concept. But I guess I'm just a little to hefty or something. It is difficult to control.The drive tires are slipping so bad it hard to drive. I all ready added 5 gallon of fluid to the drive wheels and it helped some. Plus someone had the axle bolts way to tight on the dolly swivels, But still not great. The way they are designed my weight is pulling up on the back tires and causing then to slip. Raining today so i have the time to look for some lug tires and see if I can move the dolly swivel tires back some so my weight is not lifting the rear end so bad. Any one have this problem or other suggestions.?
