With Wide tubs, What size tire?

[70blackfish]

I was looking at my truck,,,so easy to widen and fit wider tires, should be able to fit 12" wide rims...

How wide you guys running, Pictures?

My fenderwells are just mocked-up, though they've been that way for about 4 years. Try 14" wide wheels and 18.5 (section width) tires!

The 3rd pic is the 15.5's on 12" wheels on the truck until I realized I could 14s with the 18.5 tires.

I'm guessing you're a coil rear end? Truck looks like great possibilities.

Now yur talkin' Mr. Orygun!!
Go big or Go home!!

I will say this though.....try to bypass the bias ply step and go straight to the radials like the S/R or Hoosier. I can't wait to get these off this spring. They really walk on you. Not a real big deal at low speed but when you really stuff it, it's a little scary. It's like going sideways in a school bus!

+1, I'm running 20x12s with 31 x 16s Mickey Thompson S/Rs and could easily run 18 with the room I have.

I cut down a set of fleetside tubs (sectioned 4") and used them on my stepper. I'm running 18x12's with a 335/30 tire.

That's really cool!

Thanks Zoomin. Here's a pic of it (kinda) together. Pic is a little distorted, but you get the idea. I still have plenty of room for a wider tire, but I'm set on the 18x12 / 335 combo for now.

Let's get some side pics of your truck!

[BossHogg69]

NOOOO!!!! It's even uglier from the side

What are you running for a back space on those 14s and how much wiggle room do you have left.

[prostreetC-10]

Surprisingly I do have a little room. Maybe a 1/2-3/4 inch on the inside and that is based on adjusting to taste on the outside. Seems like I'm 8.5 to the inside and 6.5 to the outside (since a 14" wide wheel is really 15" lip to lip). There is certainly more room under there but the highs and lows of the bed really force you to stop where I did so the fenderwell would sit flush and look factory. Toughest part is tapering the ends so it looks factory.

I reasearched this alot before i did it. 1st off you need to know that a 67-68 rear is1.5" narrower than a 70 up so if you want to stuff get the earlier rear un less you want to pay big for wheels. Yes you can fit a 14 wide wheel with a 9.5 bs but again it has to be made. Your cheapest option is a 12 wide with a 7.5 bs wich are readly avalible and can even be found used. The max tire you can run on them is a mikey thompson 18.5 on the early rear. I run a 12 wide with a 6.5 bs and 345/55/15 and i did not have much clearance so i made some. But you also have to consider i have about 9 1/2 " of drop on my rear so a person with stock hight should be fine with that set up. If you have the later rear i would not go less than a 7.5 bs with a 12 wide. Sorry my pics dont upload with my phone but you can see a side shot in my aviator. The tires are about 14.8 wide section width however you cant get them any more but m/h racing makes a drag radial that is a 375 but its about the same section width.
