What is the biggest size tire I can put on my truck after I have it leveled??

I heard a 33 will fit, but I've also heard that a 34 MIGHT fit.

 

Depends on the amount of level, wheel offset, wheel width, tire width, tire OD.

More to it than just will it fit or not.

 

It's a 2.5 to 3 inch leveling kit. I havent bought the tires and rims yet. My boyfriend also said after the leveling I need a +20 offset to make the tires stick out about 4 inches. The guy that's doing it said i needed a -12 offset, so I'm confused.

 

7millionx12.5x20.

... too many variables man! 18s, 20s, stock wheels, offsets, mods? Conservatively a 33. Max with a saw and hammer "Put 35s on it Kinfolk "

 

Sorry, I dont know what I'm doing. Never got to do this before. They are 18" rims

 

295/55/20 is what I’d do

 

They have 18 inch wheels, im assuming stock. Personally I will be going with 33s or 275/60r20s when I upgrade. I wont have anything more than a level done to mine.

 

Your boyfriend is confused, The more negative wheel offset you have, the more your tire will stick out.

 

Definitely do a search. this is the most commonly asked question here and there are probably a hundred threads about it. And why do you want your tires to stick out 4 inches?
33s fit on stock suspension.

Sounds like your boyfriend is this kinda guy...

 

Brian, not to offend anyone, but I do not like that white truck at all with the tires sticking out like that. Hahaha... so if I done a -12 how much would they stick out?

 

A -12 would waayy out there. You don’t want that. A +20 with a 12.50 wide tire will stick out about an inch. And you could fit 34 inch tall tires with some trimming. Like others are saying it all depends on the tire size, wheel offset etc.

 

-12mm will stick out a lot! Here is my truck with 18x9 with +25mm offset and 305/65-18 tires. 33.6" x 12". They stick out about 1.25"




Offset is the measured distance between the hub mounting surface and the wheels center line.

With X being the determined offset, the hub mounting surface on positive offset wheels is X amount forward from the wheel center line. The hub mounting surface on negative offset wheels is X amount backwards from the wheel center line. The hub mounting surface on 0 offset wheels is the wheel center line.

 

When I had my 6100 level kit installed I mounted 275-70-18 At 33’s. I only had to heat the small front flap and bend it forward about a half inch. Otherwise all good with OEM rims. A fellow member predicted it and that’s exactly what happened.

 

Years ago I owed a 78 Bronco that I put wide tires on with a + offset rims, that was the worst thing I've ever done, that thing would follow every grove in the highway, scared my wife half to death while towing a small travel trailer, she said she almost put the Bronco sideways many times. Most rigs will steer the best with no offset.

 

2 +2 =4 then 4+4 is 4? Just messing with you. I had the same trouble with offset figuring. Look over this see web site and you will figure it out.

 

A 33 will fit with stock suspension and +25 offset. If you have wide flares, 0 offset will bring you to the edge of the flare. You just have to decide how far out you want your tire to extend. Every 13mm is around a 1/2”.
“-“ extends farther out. “+” sucks it back in.

You can do 35s with that kit with only minor modifications, if any....unless you have a high positive offset.

 

+25 seems to be the sweet spot.
