225/75R16 replace with 225/65R17?

[tonyiiiafl]

Found these. I tried 225/75R15 an wouldn't clear the frt calipers. So compared these 17's to the stock 16's. Thoughts? A tad slower speed at 65, however it will be a majority city car, very little highway use.

Are they off a compass or patriot? The spigot on a KJ is bigger than the hole in the centre of the alloy so will need machining out to fit.

A Patriot. So all should line up. I don’t need another set of useless tires lying around

Well, i errored. I have a LIBERTY and these were from a Patriot! So, the center hole was 67.1MM and mine was 71.5! NO fit, SO, I made a jig to attach to my die grinder and ground off the inside ridge, which gave me 70MM. Then using the jig I as able to grind a perfect circle out to 72.5 MM. The larger hole was for my comfort that when the wheel went on, it would be centered by the lug bolts. Worked perfectly, and those 17's are smooth and quiet!

I hv men look at me like i rode the short bus when i tell them that my 03 Jeep Liberty has 17" tires (235/65R17), but the rims are original stock 16". Says right here in chart that they are compatible, but they still say it's not right.
