The main concerns for tire size (without considering mods to the wheel well) are width and outside diameter.  I believe, and please correct me if I am wrong, that I read somewhere else on the nest that the max width for tires (without rubbing) is 225.  You can play with the rim and sidewall dimensions as much as you want as long as the overall diameter stays within about 5% of original.  Too small or big and you will get an incorrect reading from the speedometer.  Although the speedo is hooked to the tranny,  it is calibrated for a certain tire size.  So the tranny will be doing 55mph, but the wheels may be moving faster or slower depending on diameter.

Cheers

Our speedos are hooked to the transfer case -- but yes, you are correct.

My latest SX4 had 215/75s on it and they didn't rub, but the PO may have done some trim trimming that I haven't noticed yet. They're about 6% oversize.

Yeah, the factory spec for the sport tires is 215/65 Goodyear Eagle GT.  That's what I went for on my Kammback.  They're not huge or anything, but definitely much beefier than stock.  There is plenty of room for more tire, though.

Hey Wizard, The ( 75 ) is why you might get some rub, I want to fill those old oversized wheel wells as much as possible without cutting or lifting anything so when the time comes I'll go with the 225/65/15's. I got a set of those Jeep hurricane style wheels on auction but they will need a lot of work.

Im runnin 235/75/15s i think theres a bit of lift but the springs r so sagged its prolly null... I custom aligned mine 2 set the tires dead center of the wheel wells... I get just a hint of rubbing when im at a steering angle where the outter wheel edges touch the inner lower edge of the wells in its sweep... If i raise it about an inch, or suck those corners back about 3/8 of an inch im sure theyd clear..  See my project thread 4 pics as proof..  Lol i should hav new springs n shocks on order 2morro.. With those they shld clear with ease well enough im speculating!

if i ever get around to afford new tires i'll try the 225/65/15 s n see how they do... nice thing is i work at a fountain tire so i can have swapped for a bit smaller if needed. With my 235/75/15s they just barely rub, and just a hair or two smalller should be good...

I'm curious about the offset... I went to a tire place to look at rims today and I told them "Jeep" wheels to keep it simple. I told them it was for an 80's style 5-lug Jeep.... then he asked a bunch of questions and I ended up telling him it was an Eagle and he looked up some info on his handy dandy computer and he said our Eagles have a front wheel drive offset...

is this true? or was he mistaken? I know my Blazer had a wierd offset and I hated it... but I never remember my SX4 giving me any issues. I could simply slap any Jeep wheel on and go.

My Eagle is a 1980 model... does that make a diference?
Its got style... its got class...
It goes the extra mile... and still kicks @ss.
