3.5 ready lift 37" tires

ive been looking at ready lift for months now talked to a local off road shop and from the information that i seen online that 37" tires would fit!!!!! wrong... then i go and check online and the webpage has hanged the info that a 3.5 would max out at 35" tires. Now i'm here with 37" tires on the truck but there is a bit of rubbing even after trimming the front bumper side brackets. DOes anyone have any inputs on what to do without changing the kit, maybe adding to it. i just do not want a huge lift, just got rid of my other truck with 11" of lift.

I have not seen anyone running 37" that didn't have a 6" lift. I don't know of any way to increase the lift of that kit. I think you are going to have to buy a proper 6" lift to run 37's safely.

I went through the same thing. I have the Readylift 3.5 SST and thought I could make it work. I got a great deal on used tires (37 13.50 20 Pro Comp X Terrain)
But got sick of not turning lock to lock and feeling like I was gonna rip the bumper off, I wound up buying new Nitto Trail Grappler M/T 35 12.50 20. Any chance you could work something out where you bought the tires and get credit towards a smaller set? Might be your best bet?

Welcome to FTE...

Thats what im thinking im going to have to do.. I was trying to not do this just because there monsters sit up way up with a 6" lift. Carli also has the 4.5 lift and they do fit, I will see and post. I tried posting a pic but im new to this and its just showing up as a link.
Ive trimmed enough to where they only rub while backing up. but i still need some clearance.

You need to insert the IMG file in the post box or insert the image location link (url or http:/ address) if your using the option in the post box.

Trimming for driving on asphalt is one thing, but remember that not every parking lot entrance is smooth and most have a curb and gutter pan or some sort of bump. You will cause damage to the tires or the truck if you are not really paying attention. I know it's not what you wanted, but you are trying to run 37's...that's a lot of tire.

Readylift does a 5" kit which they claim on the packaging will work. It has a pair of replacement coil springs and I think the radius arm drop has the holes drilled a bit farther apart than the radius arm drop that comes with the 3.5"

I'd really love to have your problem right about now, since I want to go a bit higher and have proper sized coil and leaf springs and shocks instead of spacers and blocks and shock brackets but don't want to buy new tires again!

yeah, its been a long day looking for solutions but the best thing like most of you have said is to go up to the full 6 inch lift. i wouldn't want to mess this truck up. It sits good on a flat surface but not eveything is smooth like you said-SavageNFS- and those tires are not cheap to be buying every other month from getting cut on that bumper.

Your truck looks really good! Prefect tire to wheel well gap ratio.

I have an Icon 4.5" lift and run 37x13.5 without any rubbing.
You have to remember, it is a combination of lift and wheel width/offset. If you don't want to lift more, find a wheel that spaces the the tire away, ie. More negative offset.

Why? I am running 35's (285-75-18) on my 250 with no lift. So 37's should fit with a 2-3" lift.

I will disagree with you, but I have no idea what truck you are referring to (year or any other details about the offset, tire type, etc). I have the snow plow prep springs with a 2.5" leveling kit on my truck. It raises the front end approximately 3" over a regular stock 4wd truck. I also have 35's with 9" wide wheels and a -12 offset. My tires rub at lock when pulling into parking lots or backing out of driveways at lock and off road occasionally. My truck is not a pavement princess and goes off road 3 weekends a month for about 8 months a year.

I put a set of Toyo Open Country MT's 37's on (from a buddy's truck) to try and they rubbed on level asphalt before I could even get to lock with my 3" lift. If you are running a different offset with an all terrain tire, then maybe you can get your a 37" tire to work. Perhaps you could share your experience with the group and provide pictures and details rather than question what I have done and proven many times over. My tire sizes and wheels are in my signature. You might be running a unique wheel with just the right offset that helps the OP. I'm not even sure of the truck you are referring to or the type of tire? An mud tire is going to rub before an all terrain.

Ok I'll jump in with some info on my lift and tire combo.

I went with a 4" lift and 35 Terra Grapplers. I could not get 37" tires under it and not have it rub. In fact I had to take the ford mud flaps off as they would rub at full turns.
I would have had to go 6" lift to get 37".

I don't really see how a 35" would fit on a stock truck. Now that being said I used to install tires. EVERY brand has a slightly actual different size to them. Just because they say 35" doesn't mean they are, they could be 34 3/4" or 35 1/4" even. So that could be why 35" could be fit under a stock truck. It could be a small 35" tire. To me a 35" under a stock truck would look to stuffed in there. I need a little space in my wheel well. But that's just me.

I think it has more to do with width than hight. The toyos (which tend to run true to size) on mine are 34.8" and yes they fill the well but there is absolutly no rubbing. It all comes down to width I think. It's probably hard to find a skinny 37 like the 35 on mine which is a skinny 35 same width as the 33 many put on. Many will put on say a 285-75-16 for a 33. Whereas I have 285-75-18. So what size tire did you put on? hight and width. If you went with a 315 or 325 thats why.

4.5" lift and 35" Trail Grapplers. 37s need a 6" lift.
