Age old question about tire size

Postby cajun66 » Tue Nov 24, 2009 5:24 pm

My 85 BII is bone stock and had 205/75/15 tires on it. 3 wouldn't hold air more than an hour so I mounted a set of 235/75/15 retread mud tires I had laying around. I like the look but they look like they'll rub the fenders while turning.

What's involved in a body lift? I've never done one. I have a friend who owns a plastics machine shop and I can get the body pucks easily. But what else is involved?

Going to send you to another site for the information you ask for:
http://www.therangerstation.com/tech_li ... t_lift.htm
http://www.therangerstation.com/tech_li ... yLift.html
Read both articles, pay attention to lowering the radiator or you will loose some of your cooling.
There has also been something said about the emergency brake cable being a problem.
If your front springs are in good condition, you shouldn't have any problem with the 235"s, they came stock on B2's with 3.73's. The front springs are easier to change than installing a body lift.
Check to see what gears you have if you don't already know, with 3.45's and the 235's you will be changing clutches prematurely, but you may also see an increase in mpg on the highway.

Thanks Ray. The 235s look good on the truck but I'll brobably stick with something smaller when I think on it. The truck will see only mild offroading and mainly be used to pull my boat and maybe my Willys to the trails.

I believe that is the correct way to go.
What gears do you have?

I did a 3 inch body lift on my 84 and didnt run into any problems. Im running 31,s on it and she pulled fine, even chirps them occasionally. stock 2.8, clutch and rear. hardest part was putting them in, did one side at a time. It leaves a gap on the front and rear bumpers though, and the shifter is a little further down. Had to trim the fan shroud but it still pulled enough air to cool it. If you do it I'd get all new body bushings too, poly if you can.

To be honest, I have no idea.

On the front and rear differentials you will find a steel tag that is held on by one of the bolts, it will have something like "3.45". The 3.45 being the gear ratio.
An easier way is to look on the door or door frame for a whiteish tag that will have a code like "42" or "D2".
Find one of them and it will give you an idea of what you have, most were either, 3.45,3.73,or 4.10. I did see one in a 86 or 87 that was 3.23, I believe that is the right
ratio.

Axle Code "44"? When I pull the transmission today, I'll look for a tag on the axle.

Google search turned up 44 is 3.73 regular axle (non limited slip).
Thanks for the turn in the right direction. Tag on the door also calls for 205/75/15. Tiny.

They are tiny, going to 235's will probably give you an increase in mpg, but you will loose a little on the take off.
The speedometer change will be about 4 mph with the larger tires.
You can go to 30's without much problem, be be aware of the above statement. The 30's will look better too.

I have a set of 215/75/15 snow tires (In Louisiana. Weird, I know) that are on a Samurai I have. I may try them until I decide what to use.

In Louisiana? Well I have it on good authority they have winter there too, just a different type than we have in the northern climes.
The 215's will work great.
Does your truck have a tach in it? Curiosity.
