Need some tire and wheel advice.

I have a stock 2006 outlander 800XT. From my research, I was pretty sure rims were same front & rear (12×7). It has the aluminum rims. I wasn’t able (and didn’t) verify this and went ahead and ordered four Kenda Bearclaw htr’s all in 27×9.

Well, I got the tires, took them to the shop for mounting and every indication is that the front and rear rims are different by an inch or so. The stock tires were still on rims, so didn’t get exact measurements, or confirmation.

Bottom line, will it damage the machine to run the 27×9’s all around if the rims ARE different widths? Net affect will be slightly different heights, different sidewall stiffness,?? ….other con’s?

I appreciate the help.
