What am I doing wrong? 37" toyo mt

My problem is I went to a 37 for better performance when using the truck. Seems as if I'm going to be unable to run the truck hard. I have taken all the precautions spent all the money still doesn't work

37 is fine...in 12.50 wide and/or depending on brand. Toyo MT 13.50 is essentially a 14.50 wide, most people running this size have other modifications to suspension.

Just a little food for thought - I am on Icon 3.0's with the height set near top perch. I have a '14 and have put about 15k miles on it at this height. Did the Colorado Raptor Run - about 450-500 miles hard off road stuff. Haven't had a lick of problems with the front end.

I recently installed Boatec fenders and did all the necessary trimming. Put on 37" General Red Letters and had plenty of room. I didn't have to trim anything other than hammer the pinch welds and removed a little from the bottom of the firewall to get the ADD Inner liners to fit.

I think with stock shocks and that big/wide of a tire, you should consider going to top perch to make it all work together. 13.5 tires are going to definitely need that extra clearance to work.

Good luck!!!

Thanks guys

Or buy 3.0s! Good luck with this. I'm interested to see your solution.

Referring to Skyler's build here. She's running same tires (37x13.5), Glassworks and as you can see from these pictures there is plenty of room for tires. She also on mid perch. Is there possibility you body shop didn't install and fit the fenders correctly. It seems it takes quite bit fitting and cutting to get them aligned correctly?

It's weird, but from the pictures it looks like his tires are almost rubbing the firewall. Plenty of clearance at the fender. That's why I mentioned the alignment / toe-in solution. Everything is so close to the actual firewall that I don't think you could trim anymore in that area......

I had to run on top perch even with the Boatec fenders and 37 x 13.5. Installed RPG 3.0 before adding the ADD Inner liners.

Skyl3r is running fox3.0, not stock. Also, referring to the pics which is pretty identical to mine; it's not the fender that's the problem with 13.50 at stock mid perch, it's the pinch/body.

Also, @Luke13 be aware of top perch issues on 13+ while running in 4wd - search the forums. Blows up CV boots or some nonsense

it's hard for me to tell from your picture... is the wheel turned in pic or straight? What size wheels and what is offset? May be dumb question but you don't have wheel spacers on it??? if wheel is straight, offset and tire width shouldn't matter, but as you move wheel outboard, with too much offset or a spacer, your tire will rub on back of fender.
