Street Tires for 825/835/855/865, Kubota as Well
I've seen a number of posts recently about different rims and tires. First, I'm not addressing what to do after doing a 2" lift. I have no experience there. That means you are around 27" diameter. The displays program the speed correctly up to that point. Additionally, you run out of room in front first. If you have the fender guards, you run out of room faster.
First, the bolt pattern is 5-4.5 That means 5 lug bolts on 4.5" center. If you Google that pattern for rims, you'll get all sorts of stuff for trailers. That's what I use. The stock JD rims have a 1.5-2" negative offset. They are also wider than trailer rims. Trailer rims come with zero offset. Since the typical rims are 15", I've noted no problem using them. Various sites like Tire Rack and Les Schwab will talk about problems with too much positive or negative offset and all prefer zero.
So what rim? Trailer rims come in 5" and 6" widths. The 5" rims are suitable for 205 tires and the 6" are good up to 225s. So if you want to hit 27" overall diameter, you can go with 205-75-15 or 225-70-15. I prefer the later even though I started out with a 5" rim and 205s on the 855D.
Rims come in either steel or aluminum. Either will work right? BE CAREFUL. The stock JD lug bolts are a crazy 7/16-20 thread with a metric head that runs into the bevel. They work fine for steel rims and the aluminum ones JD specs for their stuff. These bolts are not trailer aluminum rim friendly as the head engages the rim which means you torque on something other than the bevel, hence the bolts will loosen.
Center hole on the rim is important too. The best fit is using a rim with a 3.19" center hole. 3.25" will work, but the JD plastic cap fits loosely. Also aluminum rims have a narrow indent for the dust cap which means the JD product is too thick on the lip. Steel dust caps are in order.
SOLUTION: You can buy many things that work. I decided on
- 15x6 5/4.5 Aluminum T08 Black Matte w/Machined Lip - T08-56545MBML rims from RecStuff.com They are 6" wide.
- LUG3K 7/16-20 Tapered Lug Bolts, Fits many Kubota and John Deere UTV's, 17mm Hex from pureoffroad.com
- AM90175 Americana Trailer Wheel Center Cap - Stainless Steel - 3.19" Pilot dust covers from etrailer.com
- 225-70-15 radials from Les Schwab
Results: I use street tires a lot because of the typical firm soil on my spread and lots of road running to the dump, feed store, you name it. Street tires give you a quieter ride, better acceleration, better top end on hills, and wear a lot better than running knobbies on asphalt. I found a good ice/snow rated radial performs better on icy roads vs. the knobbies. That is likely due to much more stiping than on off road tires. I use the knobbies in the winter as we get up to 3-4 feet of snow and I still need to get out to the chicken coop over a path that I make with the snow blower. Les Schwab had no problem giving me the mileage warranty although it would take many years to hit 60K miles.
So grab whatever configuration that will help you get more out of your gator. Besides the picture here of my 225s on my 865R, you can see a 205 steel rim application photo in my 855D Turbo review. Have fun.
