Hello i was wondering if i could fit a 33-12.50 on the stock rims... do i need to level my truck??? any sugestions please help!!

 

need more details about your truck!!!
and do a search there are hundreds of threads about this

 

Tire's too wide, your backspacing is gonna be off with the stock rims and your gonna have rubbing issues. Either new rims or spacers will be required to make em work, you may also need to level it out but I'm not totally sure.

 

If we are talking 20" factory rim than yes the tire will fit , but you will need a level lift and some spacer/adapters. Then you will be fine . I had that setup on my old red truck . No rubs

 

I have 33x12R17 and they fit with or without a leveling kit. The crucial point here is the backspacing of the rim.

 

I ran 33x12.5x17 on my truck right after I bought it for about 3 weeks on the stock wheels. Only a slight rub at full turn. My buddy with a tire shop had the Mickey Thompson MTXs I got in stock and mounted them on my stock wheels till the Mickey Classic II wheels he ordered for me came in. Once the -12mm offset, 4.5" backspaced Classic IIs went on they cleared easily. I ran these tires for almost two years at stock height until I lifted and went to 35" FCIIs.

Now to the OP: My truck is a torsion bar front, yours is a coil over, different beast. Rubberfrog might be the one to answer this for you.

But yes, as 'dog states, the proper backspaced and offset wheel is the key to get larger/wider tires to fit...
