Default Can i fit 37x12.5 tires?

I have a 1998 ram 1500 4x4 with a 3.5" suspension lift, 1.5" rim spacers and it looks like a 1" body lift. I found a great deal on 5 brand new 37x12.5 tires (250$). Does anyone no if they will clear?

May need abit more lift. Not sure though. But are you gonna out those 37's on sttock gearing? 37's will murder a trans and your gas milage if you have the stock 3.56 gears.

Please add a signature to your profile and add in your trucks details like Mutt has or like mine. That way you dont have to type it out everytime you make a post

Like Mutt said, if you have the stock 3.55 gears, 37's will kill yours transmission in short order. I'm pretty sure that I saw somewhere on here that 35's are the biggest you would want to go on 3.55's. I'm sure sombody else will chime in if I am wrong.

35's are about as big as you wanna go on the stock half ton axles, doesn't matter what gears ya got.

37's and 3.55 gears would just suck....... You would want to re-gear to 4.88. (high as you can go....) and even then, you would be munching up axle parts on a regular basis.

Never heard of a 3.5" SL but ok. I don't think you'll clear the 37s with the 3" SL and 1" BL.

Are they even true 37s anyways? Meaning upon inflation they may actually be 36".

1.5" rim spacers? So where is that on backspacing amount for current wheels? That just sounds bad from a load standpoint.

I concur with the above about gearing. People want to give other critical things to consider.

On a plus note: That is a damn deal for price on the NEW set of 37". Maybe just get them and start to plan how to get them on appropriately.

Do us a favor and a measure from the ground to the top of the wheel well. Do this on level ground and use the axle as centerline. Measure for front and rear.

You might be able to get them on with minor wheel well trimming if you really want them.

I had 35" tire with only a 3" level kit and it looked like I could stuff in a 37".

Might want to get a 3" body lift from performance accessories to make the tire fit alittle better, as ive never heard of a 1" body lift, are you sure the body lift your looking at isnt just body mounts?

You might be able to get away with fitting them. You might not. 5.5 incites is usually the minimum to fit 37's, but some trucks sit higher than others.but hell for that price id grab them and if any thing id trim my fenders to make em fit. What kind of tire are they?

There is a one inch body lift but it would never fit our trucks. One inch body lifts are usually made for little import trucks, SUV's, and jeep-like vehicles (I think there is one for Jeep models though).

Ive seen people run hockey pucks with a hole drilled through them for a cheap 1" body lift!
