while my 225's were fine on a 8" rim, the rear 245's were not mounting up well on an 8" rim. The shop tried several times, each time I was getting "excessive road force with the assembly". You could visibily see the rim protector wobbling in respect to the lip of the rim. Finally, they decided to use WD40 when beading the tire (instead of that soapy stuff)... it popped in perfectly this time. Mounted up only needing a gram on one side (opposite my SmarTire sensor). The other 245 bead was broken, wd40'd and rebalanced. While this one has acceptable road force before, it now had none. My sound levels are 100% better. It was a real hassle, this might really help you guys choosing the KDW2 in stock fitments.

 

hummm... oil + tires.. not good. i guess for last resort it's doable.
I would shampoo those tires/wheels before you mount them back on
your car.

 

they didnt use much at all, infact I didnt even have to clean the sidewalls off. the had to use it sparingly as not to mess up the TPS.
