WH_Hobie 1 #2 Posted October 22, 2008 23 stands for height 8.5 is width and 12 is rim inch size. Your biggest tire is probably the 26x12x12. I would check with Tucker tires on ebay its an ebay store thats were i get tires Share this post Link to post Share on other sites
kj4kicks 151 #3 Posted October 23, 2008 Hi Jerrell, the 8.50's are about the largest you can put on your 7" wheels. 23x10.5 tires need 8.5" wide wheels. E. Share this post Link to post Share on other sites
jerrell 1 #4 Posted October 26, 2008 :banghead: can i get different rims with the same bolt pattern and that will fit the hubs i have now or do i have to change the hubs also??/ :USA: Share this post Link to post Share on other sites
refracman 166 #5 Posted October 26, 2008 Most any 5 lug 12 inch lawn mower/ garden tractor rims will fit your tractor, but its the back spaceing you have to match up. If its inset to far you'll have problems. Share this post Link to post Share on other sites

Sparky-(Admin) 19,665 #8 Posted October 27, 2008 I think what you have are 7" wide rims (bead to bead). Thats the standard RIM width for 8.5 wide tires. The 10.5 tires work best with 8.5" wide rims. The GT1800 that I bought this summer came with 10.5 rubber on 8.5" wide rims and they were standard issue on that model. If you have the 8.5 rubber then you most likely have the 7" wide rim. The 26"or 24"x12"x12" tires wont work with 7" wide rims. If you were to get the beads to seat the tire would be way taller than the 24 or 26 inches that it was supposed to be and would not fit under the fender pan. I hope this clears up some of the confusion. Mike......... Share this post Link to post Share on other sites
Sparky-(Admin) 19,665 #9 Posted October 28, 2008 Heres a set of 10.5" wide rims on e-bay that would be perfect for the large tires your after. They also have the offset that Wheel horse's need.

Butch 194 #10 Posted October 28, 2008 Jerell I have 23x10.50x12 Deestone AG tires on 7" wheels and they look fine and work fine although it is not the recommended wheel. And I haven't had any problems with them. I also bought a pair of the 8.5" wheels on Ebay that someone above had the link to. I have 23x10.50x12 turf tire on those wheels and they have a wide foot print which I think looks pretty nice. If you plan on mounting the tires yourself I doubt very much that you will be able to put air in the wider 8.5 inch wheel because there will be a huge gap between the rim and the tire bead. A tire store will have to use a "Cheetah Can" or something like that which blows in a lot of air at once to get the tire to seal against the wheel. The 26x10.50x12 that you mentioned will be too tall of a tire. That first number of 26 is the tires height in inches. It will most likely hit your fenders. The 7" wheel may be affected if you add a lot of weight to the tractor. I don't know. It comes down to this. You can mount those 23x10.50x12 AG tires on those 7" wheels if money is a problem. If money is not a problem get the 8.5" wheels. Would I mount those tires on 7" wheels again? Definitely. Share this post Link to post Share on other sites
