Ever since we posted the sneak peek video of our new 2.2 Ripsaw tires, we’ve been getting a lot of questions on fitting 2.2 tires onto our SCX10 line of trucks. Bolting the 2.2 tires and wheels up to the truck isn’t all that difficult, but you will have issues with tires rubbing the bumpers and body. A little trim job to the bumpers and body will fix that though, and give your scale truck a little more aggressive look. For this article I am going to use our RTR SCX10 Honcho. I chose the Honcho because it has a little longer wheelbase then the Dingo TR, which will fit the 2.2 tires and wheels better. The Honcho will be the easiest to modify too, because you will only have to modify the front bumper and body.
Here’s how the Honcho looked before I got started:
Here’s a few side by side pictures of the two tires:
Here you can see this same Honcho with the 2.2 Ripsaw tires and wheels mounted, before I started cutting:
Here are a few more photos highlighting the problem areas. Notice the 2.2 tire hitting the body and front bumper way before the suspension bottoms out:
First thing we are going to do is remove the front bumper and cut it back so the tires clear it as the suspension cycles. Start by removing the center skid plate from the front bumper:
Now remove the lights from the front bumper, and pull it off your truck:
After removing the bumper, take the remaining 2 skid plates out of the bumper as well. Here you can see that I will cut along the edge of the bumper in the area highlighted by my hex driver:
After I cut the wings off I used an X-acto knife to smooth everything out:
Reinstall the bumper, lights and center skid:
Here you can see the tires clear the bumper with ease now, even when the suspension cycles:
Now, with the body on the chassis, we can check to see how much cutting it’ll take to clear the tires:
Next, I laid the cut line out on the body with a black marker, so it’s easier to visualize the final cut:
Cut the body a little less then you think you’ll need, and recheck to see if anything is still rubbing:
Here you can see the tire is still hitting the body just a little:
This is how it will looks after the final trim is done:
Now repeat the last few steps for the other side of the body:
And you’re done and ready for fun!
Overall stance after being chopped:
While this Honcho may not look as scale as it used to, the capabilities gained will far outweigh the slight loss in scale appearance.
