Hey guys I a 87 wagoner with a two inch lift what the biggest tire I can go without rubbing issues and if I did a 4.5 lift what else needs to be modified ??

 

There is a plethora of information about your topics, both on this forum and the internet in general.

Question 1: Tire size depends on how much sheet metal trimming you want to do. I have seen one instance on this forum where a guy fit 33" tires with no lift. But within reason, 31" is probably the biggest for a 2" lift. IMHO, 235/75R15 tires look great on a 2" lift, generally don't rub, plus they're cheaper and you'll still have some on-road power without needing to consider a re-gear.

Question 2: For a 4.5" lift, (again, so much information about this everywhere) You are looking at:
Springs
Shocks
bumpstops
extended brake lines
extended sway bar links
longer track bar
control arms
slip yoke eliminator with driveshaft
Upgraded steering (depending on wheeling style)

This will just get you running around and lifted up. Of course, at this point, you will now need to consider the other things like:
Recovery equipment
Armour
Bigger tires and low backspacing wheels
Regearing/lockers
etc.

Welcome to the jungle.

 

You are a better man than I. I would've stuck with the first line and left it at that lol.

OP, please learn how to use the search function. Both questions have been answered thousands of times.

 

Sometimes I feel generous (read: bored) around the holiday season

 

Ok we'll if I have 2inch coil and 2inxh leaf already on the truck can I go with 2 inch puck and shackle or block to make 4 inches altogether ?? And if so what major modifications will I have to make then ?

 

Btw thank for answering my question I kinda new to this whole jeep thing and I kinda really like it

 

Yes, you will need all of the above in bold. Your leafs will sag and hate you though. At 4" its highly recommended that you get new leaf packs.

 

you'll also need longer shocks to accommodate the added lift and most likely longer brake lines. Now would also be a good time to upgrade (if possible) your brakes. The added weight of the larger tires will make it more difficult to stop affectively.

 

To run 31"s on a 2" lift you are going to have to do trimming/cutting. I hate that answer on here... everyone says "oh you can run 31"s no problem" but they dont tell you that you have to trim. 31x10.5x15 with a 15x8 3.75 backspacing rubbed big time on XJ with a 3" Zone lift. I had to trim about an inch off the front and rear of the front bumper and trim to be able to turn without scaring the neighborhood.

 

Can I fit those tires on the stock 15 inch rims with out having a problem
