1988 ford ranger 2.0L build

[Keaton]

Can someone please help me with my rear wheel and tire sizing? I already bought the front set of wheels and tires and the rear set of wheels and tires. But the rear wheels do not fit sadly and I have to purchase a new set of wheels and tires for the rear because they won’t let me return them after tire mount.

Can I fit 15x10 on the back still?
Trying to fit the biggest I can on the rear.
I did 15x7 -6mm with 215/70/15 for the front
I did 15x10 -56mm with 275/60/15 for rear

It has the 4&3inch drop kit on it that everyone uses.

I couldn’t fit them on with my bed on. And now I can’t fit the bed back on after looking at the wheels on there. (The wheels are 3 inches too wide, so the metal edge of the fenders sit on top of my wheels) making it to where I can’t put the bed back on.

Can anyone help me please

Take the front tires off and put them in the back. Put your old rims on the front just to hold the truck up. Does the bed fit now? I am thinking if it does, it will barely fit with the front tires and rims you have.

As you have found, lowering the truck greatly affects wheel/tire fitment. Don't just focus on the wheel. Because, ultimately, the tire is the biggest part of the equation. The tire is what ultimately hits the body and suspension components.

You will need to do some measuring and "figuring". The wheel diameter and width are important. But you also need to consider backspacing or offset. These terms define where the wheel is centered in relation to the axle flange that it bolts onto. With different backspacing, you can push the wheel/tire assembly closer to the center of the truck. But, too much and it hits leaf springs in the rear or radius arms in the front. The width of the tire also affects this. A 10" wide wheel may be ok by itself. But putting a 12.5" wide tire on it makes the whole assembly wider.

Some people also stretch their fender openings wider to fit wider tire/wheel combinations. Or, at least roll the lip in a little bit. That is a bit trickier with the square-ish shape of your fender opening.

One other thing to remember is that you need extra space for when the suspension flexes and your wheel gets pushed deeper up into the wheel well. On the front, steering plays a huge roll in this also.

Here is a picture that may help you understand the different measurements involved. In this picture, imagine the axle coming from the left side.

Here is an article in our tech library with photos to show how some tire/wheel combinations look.

That's good info. And unless you copy someone else's setup exactly, wheels/tires on lowered trucks is always a math problem. At least it kinda stops at basic math.

You might be able to pooch out the rear fenders a bit, for the most part it's just held in by the angled supports, if you made longer ones it might work...
