I have a Toro Groundsmaster 7200 that calls for 24x12-12 tires, Toro part #106-7868. I purchased Carlisle tires #511409 24x12-12 that I expected to fit then found in the Carlisle catalog that the tires are listed for an 8.5" wide rim. The GM7200 has 10.5" wide rims and I don't see how they will work.
I looked up the original part number on parttarget.com and found the NSN 2610-01-644-0954 which cross-references to Carlisle 575390 tire 24x12-12 which is also listed for an 8.5" wide rim. I contacted Carlisle and the only tires they have for a 10.5" wide rim are 26x12-12.
I'm surprised I can't find much mention of rim widths in Google search or on forums or even on tire descriptions. Is this not a common issue? Will the tires listed for an 8.5 inch rim stretch ok to 10.5"? Based on the cross-reference I'm concerned if I go buy the stock Toro tires that I'm going to end up with the same thing I already have and pay twice as much for them.
Any advice is appreciated!
