41" Goodyear G275's
A few months ago I tried to do an update through my phone and thought it went through, but apparently it didn't! In any case I have been busy the last 6 months, mostly with life and getting married and not as much building truck. However I finally did get the tires on.
Went with the Goodyear G275 41" tires. In order to accommodate them I had to do a few things.
1) Took advice from another board member S2DM and went with Double Designs fiberglass fenders. They mated up pretty well, with these fenders and some clearancing/welding they were able to fit the 41" tires without a lift which was the goal to keep COG down.
Tires with stock fenders removed.
Like S2DM, I cut off the front support, but I welded in a tube bracket to support it higher up were I think he reused the stock cut off. With the tube bracket it didn't interfere with the headlight and didn't rub the tire when turning and flexing.
2) I had to move the bumper forward 4" for now. I used longer bolts and these spacers to do it.
3) Already had my tires on order from Stazworks. They do good work but it took 3 months to get them! I opted to go with the beadlock donuts and at the spacing they are completely rotatable to any corner.
4) I re-geared with 5.38 ring & pinion. When regearing I added a limited slip in the rear Dana 110, with an Eaton "True Trac". Added an Auburn gear e-locker for the front. I'm hoping this helps in snow conditions!
Immediately following the gearing I installed the tires. Final Product:
The Stazworks tires I ordered with balancing beeds. To make sure they don't get past the donut he installs 2 air filters into the holes in the beadlock donuts. Stazworks came up with that solution. When I opened up my Stazworks wheels, which are split with the plastic beadlock inside, I had absolutely no beads that got past the beadlock. Most of them were stuck to the tire where they should be actually. I ended up vacuuming them all out because I was getting a really bad shimmy at high speeds and pursued another form of balancing. When driving 10 hours a day it gets on your nerves!
My end solution to help the balancing was to vacuum out all of the beads and take them to a Goodyear truck service center who had a large enough balancer for my tires. I also was concerned about the inner beadlock donut, and was considering splitting the rim and removing it for balancing and then reinstalling marking where the tire and rim was, but I figure that in itself will cause more problems moving things around so I would just balance with them in place and hope they are negligible in how they affect the balancing.
After balancing I also added the centramatics and they seem to do well at nipping the final balancing of the tire. Perhaps they compensate for any movement of the donut?
In the end it still has a little bit of a shimmy at 65mph, but nothing like it used to! I do yearn for the days of 35" completely smooth ride tires at times, but the trade off is worth it now.
