6 Lug to 8 Lug Wheel Adaptors

[mo1]

I am not talking about a 5K series, I am talking about a 2002 John Deere 4210 compact tractor that is 28 HP with E-Hydro. The rear hubs are 6x6 bolt pattern which is a small skid steer hub. I want to put 15-19.5 tire and wheel on the back and I have found a set of 19.5 inch diameter wheels that have a 8 on 8 bold pattern. So I need an adaptor (not spacers) that bolts on to my 6x6 hub and converts it to an 8 on 8 bolt pattern. Does anyone know if that exists?

Thanks,

The 12.25x19.5 rims that a 15-19.5 tire takes come with 8x8" bolt patterns. If you wanted to fit one on a 2WD 4210, you would either need to have a custom wheel made with a 6x6" bolt pattern or have a machine shop make you one. The stock industrial tire size for a 4210 is 14-17.5 on a 10x17.5" rim, and as a 15-19.5 is larger, I would NOT put this on a MFWD tractor, lest you screw up your lead-lag ratio and wreck the front axle.
