NWjetboat,
I run 26" mudlites on C series T-5 wheels and they stick out about two and a quarter inches beyond the fenders(I measured). My first time out with them I came home looking like "MUDMAN" lol, not to include getting mud all over the top of the machine, where before I never got mud there. I quickly purchsed the yamaha over fenders and my problem was solved. Mud still gets thrown on the machine but no more then when I ran stock tires. I also noticed with the over fenders that the mud and water want to seep through between the stock fender and flares. What I have done was an easy fix. I bought some foam insulation tape from my local hardware store and stuck it to the flares then bolted them back on. this created a seal to stop the water and mud from penetrating through onto the flares. I hope this helps.
Ride safe
