Will backspacing solve the issue?

If i remember correctly, one of the main issues with getting bigger tires under the Patriot is due to the spring perch, and the tires eventually will rub/hit them.

If you were to buy some wheel spacers, or just get new rims with a different backspacing, would this push the tire/rim out far enough to get around the problem? I dont own one yet, and im not state side, so i cant really look.

Im guessing the backspacing would have to be pritty extreme though.

Just a random thought...

The wheel well opening is only 32" and there is about a 1" nub on the rear liner (that can be removed). Stu's Aussie lift gets rid of the spring perch that's in the way because it's replaced as part of the spring. Also if you go too wide a spacer you could start having problems with the CV joints. I would think that 1 1/2" spacer would be max. Another problem with too tall a tire is that you will loose some of your bottom end "crawl ratio". You can get away with losing some on the FD II but the FD I needs to maintain as much as it can. I've got 29" tires on mine (FD I) and it's still OK but if I'd drop down to 28" I could do better around town and on the road. Still, tread pattern is more important, to me, than height. Another reason that I like skid plates.

Thnx gramps... I really want the aussie lift... but ill also be getting the FD1 (need manual) so ill take the crawl ratio thing into consideration...

I figure lift/tires/skids/ and tow hooks will be all i need. Plus a CB.

To figure your new ratio:
(Original Tire Diameter / New Tire Diameter) X Original Axle Ratio = Effective Axle Ratio
Example:

On my stock 18", CVT w/ 14.37 (1st gear) and 6.12 final drive it's:
(27.3/29.1) X 14.37 = 13.48 (1st gear) or 5.76 (final)

With the 17", 5 speed with a 14.74 (1st) and 3.91 (final) it's:
(27.2/29.1) X 14.74 = 13.77 (1st) or 3.65 (final)
