bigger tires for a 1992 4runner help

[4x4ers]

Greetings!!!

Good day to you all,
Good day all! own a LN135 toyota 4runner.

Its on 16 inch x7 stock steel wheels. initially i got it with puny tires (see above pic), but i managed to find some second hand pirelli scorpions (265/75r16 or 31.64 inches) that are good for about one year of use. I installed them with no problems whatsoever.

Now however, its time to change them again. I am currently looking on some ROH black trak or bearcat rims. i'm eyeing either 15 x 8's on negative 50 offset or 16x 8's on negative 50 offset.

if i do go on 15's, im planning to put 32 x 10.5 or 12.5inch all terrain tires. whichever is available. If on 16's however, im planning to get the same 265/75r16s all terrain.



Now my question is:
Is it a good idea to get them -50mm offset rims? wouldnt that create complications??

Would shifting from (265/75r16 or 31.64 inches) stock offset tire/rim combo to 32x 10.5 or12.5 all terrain tires create problems for my rig? i can lift the rear, just not the front as cranking the torsion bars will shorten the cv's life. by the way my 4runner has torsion bars front, and leaf springs rear.

Im operating on a student budget, so i really have no room for mistakes. I want to make sure before i make my purchase.




These will really help me a LOT!!! Advance thank you to all.

btw here is a photo of my rig with them 265/75 R16x7 wheels

here it is testing (slightly smaller) 31x 10.5 R15 kumho a/t tires

and here it is testing some aggressive (slightly bigger due to the thread) 31x10.5 R15 federal couragia Mud tires

I'm not sure about the offset question, I would compare to the stock rims and go from there.

Since you have manual hubs installed, cranking the t-bars won't hurt the CV joints when you're in 2WD. The only time they will be slightly stressed is when your hubs are locked in. You might want to take a closer look at your rear suspension, there should be coil springs back there, not leafs (unless it has been converted).

Where are you located? What engine do you have?

Hello.

Im from south east asia, the Philippines.

just double checked, its on leaf springs. I guess since this is the 1992 model, I believe the coils were introduced around 1994 if im not mistaken.

I have a toyota 3L 2.8 liter naturally aspirated Diesel engine,with a 5 speed manual transmission. so there isnt really not much fun on the highways with regards to the power. but im happy with it. The engine just got rebuilt by the way.

Really? i didnt know that. Thank you for that very helpful advice. I seldom go offroad honestly, because im afraid i might break something and cost me a months allowance. So i use the 4x4 mode only around 3% of the time.

the stock rims are zero offset, i plan to install negative 50 or negative 40 offset wheels so that the tires go beyond the fender a bit (its kinda a fad here). Plus i wouldnt have to worry about the rig not being street legal as everything here is street legal as long as it passes the emission tests.

Wow, that is very interesting. All of our 4Runners in that generation (1989-1995) are coil springs in the back. I'm sure we'd like to see some photos of the setup!

also i don't think 16" rims came stock until the tacoma.

@ KLF and liveoak

Thanks! Im having thoughts about the 32 inch tires. I might put some 31 inchers instead to have sufficient fender clearance.

And yes, its on stock rims! Theyre a bit ugly, steel rims. Your 15 alluminum alloy wheels look a lot better.

I will update you guys when i crank the torsion bars a bit and how i will lift the rear. Will also post here the pics of the rear leafs.

 

[4x4ers]

As promised, here are the pics for the leaf springs:

They look straight and "tired" already. Maybe its time to replace or hammer them to the right specifications?

I think it looks great in the first photo and wouldn't change a thing. You're on a budget, right?

really? i think the very first photo is rather silly because the rear tires are smaller than the front tires there. Good thing i didnt engage my 4x4 system then, else my tranny might suffer from wind-up.

the second photo is what it looks like right now and it needs new tires. Thats why im planning either to get either these:

these:

or these:

all are 15x8 inches wheels.

also, yup im on a budget as i am still a student. not yet working. maybe when i graduate i will have the cash to really make this rig shine.

right now im not into hardcore mods, just maintenance mods.

 

[4x4ers]

Please forgive my grammar on post #10. What i mean to say is, since i need to buy new tires, why not get a new set of wheels that will look nice with it too.

Man you guys get all the good stuff. In the overseas markets I believe they carried the rear leafs longer, heck I think the solid axle fronts hung around until into the 90s.

With regards to your offset question, I don't think you will have a problem with that offset. If you did it would be on the back edge of the front bumper or at the rear of the fender because you will be pushing the outside face of the tire out which will intern make the turn radius of the tire slightly larger.

As far as tires and wheels, before dropping down to the 15" wheels, double check the diameter of you disks and drums. Here in the states we got 15" thru 95, and since your rear looks like a US market pickup rear setup, my guess is you will be good on 15's. I felt this was worth mentioning since you mention your budget constraints.

I would also stick with an all terrain since you are not off road that much. You will get much better wear and value out of the tires you end up with.

Good luck and welcome to MUD.

thanks for your insight matt. i appreciate it.

i believe in the USA, they dropped the front solid axles and the rear leafs and replaced them with independent front suspension with rear coil springs in the interest of cabin comfort. My friend has a 1994 SR5 4runner here with 3vz-fe and the rear is on coil springs.

will do double check first if those 15's fit before i buy them. so that fitment is sure.
thanks


if i may, whats your take on the 32 inch tires question? should i stick to 31's or upgrade to 32's?


here is the other wheel im planning to fit on my truck.

 

[jynx]

On the tire size, is your truck a manual or auto transmission? And how are you doing on the 265s right now? A manual will be much easier to deal with a slight increase in size than a auto will.

The overall outer diameter of the 265 (@ 31.6") on a 16" wheel is going to be very close to a 32" (most actually measure about 31.5"), so between the two I don't know that you will notice much difference. The 32 will be a little heavier since there is more rubber there.

If the 265s are doing ok for you right now then I would say you will be happy with either.

I am looking at stepping up to a set of 265s from 31s next tire change myself.

As far as budget, in the states a 32 or a 265 is going to run about 15% more per tire than a 31x10.5

 

[4x4ers]

Hello i have a 5 speed manual. Im good on the 265' s right now. No scrubbing or any problems whatsoever. Fuel economy is the same with smaller size tires.

Hey thanks for that.! I had no idea that 32s were really just round 31.5's.

Goodluck on your tire upgrade sir.

@all. I have made up my mind. Im going to lift my rig some 2-3 inches using extended shackles at the rear and torsion bar cranking at the front. Then i will look at either 32*10.5*15 OR 265/75/16 tires. Then depending on the price and availability of the tires, i will choose one. I shall test fit the wheels first, then the tires. So that im sure. Nevertheless i will update this thread when its wll done. Thank u.!

Before you crank the front T-bars, you should install AISIN manual locking hubs on your front axles, your CV shafts will thank you by lasting a lot longer.

 

[4x4ers]

KLF

Thanks man, got it! but i think i am already on aisin manual locking hubs... what difference does it make if its manual locking from auto locking?

 

[KLF]

My mistake, I assumed that last picture you posted, of the front wheel, was your truck. But now I realize it's an 80-series, not your truck.

 

[4x4ers]

man youre good! yup that is in fact from an 80 series land cruiser.

Its alright, i appreciate the warning/precaution.
