hey all, new to this so sorry if i posted in the wrong thread or section. i've got a 77 CJ5 with a AMC 304 in it. right now its got 33s on it and i'm looking to lift it a bit more and throw on 35s. however, my dad says he's tried this before but the larger tires hit the inside of wheel well in the front when turning... is there any way i can get around this? hopefully its not too much money to work around it. oh and the tires on now are 33x9.50

thanks in advance
 
Sounds like the wheels didnt have the correct off set for the Jeep. You can solve that by having a wheel with less backspacing , therefore pushing the tire outward away from the inside fender. The downside of this is if you need tire coverage by law you'll have to get wider flares. Tj flares are a bit wider than Cj flares and you can trim the sheetmetal on your Jeep to open it up enough for 35s without adding any more lift. Tops youd need a 1 in. body lift. Also most 10 in wide rims have minimal backspacing giving them a deep dish look and placing most of the tire toward the outside of the fender. Heres 10 in. wide with 33 x 12.5 on my old CJ7 . Didnt rub at all. 35 x12.5 wouldve fit with Tj flares.

Well, I have an '80 CJ7 with 35X12.5's. The wheels mate to the rear hubs with an aluminum offset insert. The insert, round machined AL about 4 inches deep with bolt holes to mate to the hub, is bolted on with wheel nuts. The wheel mates to the insert, giving the offset needed for clearance.

I have 'em off now for axle replacement; I'll take a photo tomorrow and post it. Dunno what's in front; haven't had the front wheels off, but I suspect the arrangement is the same all 'round.
 
yeah, i've heard bad things about wheel spacers. so what i should look for is a wheel with less backspacing?


I think this will help you.

How to Measure Wheel BackSpace


tech-backspace.gif
Items required to measure wheel backspace:
abstrbu1.gif
Tape measure
abstrbu1.gif
Straight edge
abstrbu1.gif
Wheel w/o tire (preferred)

The easiest way to measure backspace is to lay the wheel face down onto the ground so the backside of the wheel is facing up. Take a straight edge and lay it diagonally across the inboard flange of the wheel. Take a tape measure and measure the distance from where the straight edge contacts the inboard flange to the hub mounting pad of the wheel. This measurement is backspace. The above photo shows three wheels with 2",3", & 4" backspace.

Measuring Wheel Offset

To calculate offset you'll need the following measurements:
abstrbu1.gif
Wheel backspace
abstrbu1.gif
Wheel Width
abstrbu1.gif
Wheel Center line (outboard flange to inboard flange measurement / 2) Subtract:
abstrbu1.gif
Wheel center line from Wheel backspace to get offset.
abstrbu2.gif
If backspace is less than the wheel centerline the offset is negative
abstrbu2.gif
If backspace is greater than the wheel centerline the offset is positive Tip:
abstrbu1.gif
To convert from inches to mm multiply by 25.4
abstrbu1.gif
To convert from mm to inches divide by 25.4

Determining Vehicle Fitment


Fitting a wheel and tire package is different for each vehicle, but by following these guidelines your chances for success will be much greater. In most cases you'll have to use the physical dimensions of the current wheel/tire package to determine the dimensions of the new wheel/tire package. Items which are potential trouble spots:
abstrbu1.gif
Tie Rod Ends
abstrbu1.gif
A-arms
abstrbu1.gif
Brake Calipers
abstrbu1.gif
Shocks and Shock Mounts
abstrbu1.gif
Inner & Outer Fenders (esp. front tires turned to lock)



tech-wheelfit.gif
In the drawing on the left, we've made two measurements
abstrbu1.gif
Front Side Clearance
abstrbu1.gif
Back Side Clearance These measurements when used with:
abstrbu1.gif
Tire Section Width
abstrbu1.gif
Tire Diameter
abstrbu1.gif
Rim Width
abstrbu1.gif
Rim Backspace Help determine if wheel/tire clearance is adequate for the new wheel/tire package you've selected





Suggestion: Start your search for new wheels by picking the tires first. Get the tire manufacturer's rim width recommendations and physical dimensions for the tires you want. Pay close attention to Section Width and Measured Rims specs., these are important numbers to be used when selecting rims and determining vehicle fitment.

As far as laws about wheel coverage. You need to check the
'"Motor Vehicle Code" in your area. Some locales do indeed have such laws, but they are far from universal. There are no laws like that my 5 state area.
 
Hey, 304cj77:

Here is a photo of the hub extender that gets the 35x12.5 MT Baja series off the frame and out where they should be. If I were going to really pound the rear axle off-road (can't ... old war wound gets fussy about even badly potholed local streets), I would want a wider axle. Every new junction, joint, or bolt attach point is a potential failure and potential problem for the Jeep owner.

 
About 23 years ago I was running down I10 in the middle of bum f*&k texas when a wheel spacer gave up the ghost and I watched the front tire of my van go rolling on out into the desert. Well needless to say after getting a Texas Trooper to stop and call me a wrecker, spending a few days in a micro town in Texas waiting for parts and then paying way to much for a repair, I decided to just never run a Spacer again. I was on super slab when it went.

I've never run any kind of spacer or wheel adapter for just that reason.
They always looked dicey to me.;)
 
Way too much leverage on the hardware.:eek:
 
yeah thats what i've heard, definately not using spacers. as of now my jeep still has the original wheels, so im thinking im just gonna look for a set with minimal backspacing
 
I've been running 1 1/2" wide spacers on the TJ for about 4 years and never had a lick of trouble. This is one of those like em or not deals, and the spacers won't actually put any more stress than if running little backspacing and pushing the wheel out.
 
Ran some MT wheels and 33x14.50x15 Super Swamper TSL's, with no rub on a 4" super lift.

35's woulda been easy in a 10.50 or 12.50
