Hey guys when I bought the MX5100 I opted for the R4 tires instead of the R1's. Mainly because the R4's are quite a bit wider, and I was doing alot of grading lots when I first started. Now for the past couple of years I have been doing more land clearing and field mowing and I have noticed the R4's kinda suck. When moving dirt or pushing into a big pile of brush the R4's like to spin. I have them filled with water and I was going to hang some weight from them but was wondering if I should go with a whole new set of R1's before getting the weights because they are different rims. I know it will probably be costly, so just wondering if anyone had any thoughts on if the cost will be worth the improved traction if any, or would it even be worth it?
