I drive my deuce rather a lot using it to run back and forth out to reenacting events carting all my goodies around as well as for various surplus shopping trips. Usually around 6-8K a year and I have been getting sort of tired of constantly having to be on the hunt for more 9.00 - 20 NDCC tires to keep up with the wear and tear. Additionally, the place I generally go offroading at has a lot of nice big rocks that always manage to find a way to get stuck between the duals giving me a fun job once I am all said and done getting them dislodged.
It did not take long to figure out that with the amount of running around I do coupled with the rocks issue I should make the switch over to single rear wheels and radial tires.
Of course, we all know that costs and arm and a leg so for many years I just constantly tossed tires at the truck onsey twosey until this time when, faced with a total of 5 out of 10 tires in need of replacement I decided to opt for a good deal on a set of radials instead.
Around a thousand dollars later I finally pulled out of the tire shop with 7 nice Goodyear G-177 11.00-20 radials (1 spare tire obviously) and finally hit the road. "You'll love how it drives" they told me...
I don't know about that... This thing drives like a rocket propelled riding lawn mower now...
It is VERY twitchy, it tracks fairly straight but any slight adjustment of the wheel makes it dart around the lane. It is quite hard to keep in my lane of traffic even at moderate speed and when rounding corners, the wheel does not spin back like it used to. It actually drives sort of like how people describe Gamma Goat's.
With the 9.00-20 tires and duals it drove quite nicely so this is entirely new behavior.
I tried up and down on the tire pressure. It was at 110 originally, I dropped it first to 90 and saw no major improvement. At 75, things seemed to get slightly worse.
My buddy Dave came over and we measured the toe in, it's running about 3/8ths of an inch at the outside of the tread which given the extra distance of the 11.00 tires does not seem excessive.
I've not had anyone follow me who could be bothered to stop text messaging for 10 **** seconds and look at how the truck is tracking so I've not had any serious outside observations yet.
I do not yet have the hubs flipped, I had planned to do that over this week but sort of want to get this ironed out first since I don't want to just have to flip them back when I go buy 10 more NDCC tires to replace these things with. Currently, I am running single wheels dished outwards on the back. It doesn't seem like that would cause weird behavior but I am not about to flip them dish in and try them since I am pretty sure the truck would roll over since it is VERY unstable right now.
Anyone with experience on this front have any input or ideas?
