I have read a lot of the archive threads regarding what size tires will fit on stock Broncos. It seem that 33x10.5 will fit on a 1994 stock truck, while 33x12.5 will not fit without a lift kit. I noticed my son's truck currently has 31x11.5x15 tires, which got me to thinking. Would 33x11.5 tires fit on a stock '94 and do they even make tires in that size?

My son plans on getting a 4' lift when he can afford it, but his tires are shot now so I am looking to pick up four used tires to hold him over. I have seen lift kit ranging from $400 and up. What is a fair price to pay to have a lift kit installed? All input is appreciated as always.

Here's another choice - anyone ever try a 32x11.5R15 on a stock Bronco? if so, does it rub when turning? I'm looking at the BF Goodrich Mud Terrain T/A.

 

Had stock 93 Bronco . Had 32.11.00.15 on 8' rims w/stock back spacing rubbed on arms ,(the 31.10.00.15 rubbed to)but was fine other wise. But it was not used offroad as it was my Sunday going to church truck.

 

run the 32's for now. If they rub on the radius arms that isnt a big deal. I have a 78 bronco running 35x12.50R15's with no lift and they rub on the radius arms in that truck and it wont hurt the tires much or the arm at all. 33's will be just a hair big and rub more on the fenders, possibly causing them to damage the fender, especially in the front when turning and making the suspension flex. 4" suspension lifts are a decent size for these trucks, but there are two options for these kits. Install might get the price closer to $1500 with the cheap kit(dropped radius arm brackets instead of longer radius arms), and closer to $2000-$3000 for the more exspensive option. These numbers are in canadian dollars. I spend around $1800 for parts for my 4" lift, but I went with new rear spring packs and longer radius arms. Body lifts should not exceed 3", and will definetly be cheaper, but I personally do not like them for the odd appearance of the gap between the frame and body, plus the truck then relies on the stock suspension to handle the larger tires and off road which can easily cause to suspension parts failure and odd driving characteristics. Hope this helps.

 

32 clear on after market wheels w/4.5" back spacing most common back spacing in 15"x8" wheels aloys will probably rub because they are 1/2" wider seen quite a few w/33's and no lift. Buy the 33's trim a little till the lift goes on

 

Excuse my ignorance, but what is “back spacing” and how can it be added? Is it the deepness of the rims which moves the tire further to the outside? This means that the only way to add back spacing is to purchase rims.

 

I hope you have better luck than I have had on this. I am wanting to put 10 inch wheels and 31 or 32's on my stock 95 but I can't find any one that has done it with out a lift. Don't forget you will have to space the front bumper out, at least that is the only bit of info I have received so far.

 

You also need to note what brand tires you are going to use as the same size tire from different manufacturers are different dimensions. If you go to the tire website most will give you actual dimensions. My 93 Bronco with no lift has BF Goodrich Long Trail 31-10.50X15 tires on 10"X15" wheels. They rub when you turn it all the way to lock as if backing into a parking space. My 90 Bronco with 3" body lift has 33-12.50X15 (with 10X15 wheels) BF Goodrich All Terrain T/A's and no rub ever. I put these wheels and tires (about 50% tread left) on my 91 Bronco with no lift and they are fine, no rubbing. The 92-96 Broncos have a different bumper and it sticks down differently at the bottom towards the tire. You can space the front bumper out for clearance but I would think it would have to go out at least another inch.

 

I have the 32x11.50 MTs on my 95 The only part that rbed was on the bottum inside corner of the front bumper. Ihave heard some say to shime it out 1/2 inch, I just took a cutoff wheel and trimed that corner off the bumper it is not visable even iif you know where to look.

 

I had 33x12.50's fit on my truck with bumper rubbing only. I had them tires mounted on 15x10 Cragar "soft-8" wheels however, so I'd imagine that the backspacing was a big help on this. I ground the corners of the bumper off and had no further problems. I have since added leveling springs, which make it look much better.

 

sorry to leave question unanswerd for so long you are correct in your assumption of backspacing. I read the rest of the answers to your question the problem is they all hafve 10 inch wheels except for BLUE his fit better because Crager soft 8's are only 9" wide givineg him the correct backspacing w/only 1/2" negative offset(distance away hub center) where a true 10" wheel gives you over 3/4" negative. That in turn puts your tire in the rear of the front fenderwell

 

Again, thanks for the info. I have settled on either the BF Goodrich Mud Terrain (width 11.4" on 9" rims and 31.8" dia.) or the Dunlop Radial Mud rover (width -12.2 dia- 31.3) I like the Komho Road venture MY KL71, but can't find them anywhere near by. The wheels (not sure if after market) measure 9". Looking at the measurements, I assume the BF Goodrich would be less likely to rub on the radius arms but more likely to rub on the fenders. Any suggestions?

 

i have 32x11.50s BFG/ATs, the look cool, and have great traction, but they rub on the control arms, and on the swaybar when turned to the locks. also another note, the kill your milage and power, unless you change the gears. i actually get better milage in my 93 Lightning with a 351 and 4.10s on stock rubber, than i do with my 91 bronco 302, and 3.55s with the BFGs.....

just my $.02...

 

I was able to get no rub and plenty of clearence on my 87 stock height with mickey t's classics 5" backspacing 15"x10" with a goodyear radial A/T 33".I spent $875 for the whole set and i've been running them for three years.They have about 84'000 miles on 'em and they still have half their tread left.

 

27000 miles a year on a Bronco has to cost an arm and a leg in gas.
