I've scoured old posts for the last hour, and still am not sure if I will be able to fit 33's on my stock 86. I've found every answer under the sun. I've got a set of 15x10 rims. Anyone out there running this set up?? Please let me know. Any rubbing? How bad? I can handle a little bit in tight turns. Will I have to space the bumper? How about a 1.5 inch leveling spring kit? Thanks
I also did the same inquiry. I found that if you want a stock set up that won't rub, then go with 15x8 with 31's....32's will fit, but they will rub in the inside. 33's need to have a 4" lift....35's with a 6". You should have went with 15x8's, 10's are alright, but it seems that people need to do more research on backspacing with 10's.
I posted a thread about this exact thing yesterday...ive got an 86 too, stock height, but say if I went with 33 Bfg mt's...would that make a difference between 33 Bfg At's? Bigger lugs? Hopefully in the next few weeks ill be walkin with new shoes.
Thanks for the replies-Quite a range of replies. One says I need a 4 inch lift for sure, another says stock is fine with no rubbing. I understand each vehicle may be a little different, but this is a big range. Any others???
To be on the safe side, go with a lift....31's or 32's. People also might have different offset spacing, which makes each one different. Best thing you can do is go to a your better tire shop and ask if they have an tool that can mount the tires you want on a special tool (looks like an adjustable rim) and play with the offsets. Make sure that you turn the wheel from extreme left to extreme right. This will for sure give you the correct size.
i say install them and see where your at then. if you need a bit more lift you could always get coil spacers up front and aal in the rear probably for less then $200.
Offset spacing is the distance between the mounting surface on the inside of the rim to the bead of the rim. To check this distance put the rim on the floor (with no tire mounted) face down. Put a 2X4 across it ( or some other straight edge) and measure from the 2x4 to the area where the studs go through to bolt it to the truck. That is your backspacing for your rims.
