Thought there may be some interest in this so I am reposting this from another section.
Ok, here goes. Overall there is next to no information out there on modifying a CX 50 to make it more off pavement suitable. How do you build a new model targeted at the outdoors / offload market and deliver it with 20" wheels and low profile street tires? First, the stock wheels are 20x8 5x114.3 bolt pattern with a 45mm positive offset. Those numbers are stamped on the backside of the wheel. I weighed the stock wheel / tire combo at 65lbs....not lite. I'm going to try 17x8 35 positive offset KMC 545 Treks ( not my first or second choice but both of those are on backorder) @ 26 lbs mounted with Toyo AT III 235x65x17 tires @ 33lbs. This combo will give me over 1.5 inches more sidewall, 0.4" less width, 0.34" bigger diameter and around a 60 lb weight once mounted and balanced. Everything is ordered and I'll update results and include pics once completed.
