tire size

[CB Fab]

running 3.5 duff lift want to run 33"s should i use 10.5 or 12.5 width.Thanks

 

[johnmlebel]

cut or uncut?

 

[broncnaz]

I like the 10.50's with my 2.5in lift. No rubbing on the radius arms at full lock either like 12.50s usually do.

 

[zerostar2410]

will 12.5's rub with 3.5 backspacing with H1 tires?

 

[got-broncos]

How wide is the rim your using?

 

[tennessee toy]

if you run 10.50's you have nothing to worry about.

I've got a lot of weight on mine, sitting with about 2.5" of lift (squashed 3.5" duff springs)
running 33x12.5's on 15x10 rims. no worries.
I dont wheel mine real hard, so your mileage may vary....

the cut/uncut question was an excellent point though.

And what size rim is he running..? 10.5 or 12.5 will be okay, depending if it's cut or not fur sure.

I run 12.5 on a 10" wheel but it looks too wide on a 33" tire IMO. I will be going 10.5 on 8" wheels when I come up with some $$$.

I don't have any problems with rubbing. .. I have cut fenders.

rim is going to be i think 9 inches wide by 16.5 tall. They're the H1 rims. Think they'll rub with 37x12.5's?

I think you would need a body lift or fenders cut to the body line to clear 37s w/3.5 lift

I have two set ups with 3.5" lift and 33s One is a 10 wide rim and 33 x 12.5x 15 BFG MT the second is a 8 wide rim with 33x 12.5 x 15 Procomp MT and both fit just fine I like the look of the 8 wide rim a lttle better than the 10. I also have a 1" body lift on each truck and could probly get away with 35s on an 8" rim but it would rub off road. I dont think you could get 37s to fit with out a 2" body lift but even that it would be close!

To the original poster's question, either should be fine if you're cut. The 12.5" tires will probably rub the radius arms at full lock, but only if you're running the factory arms. If you've got the Duff arms, then you've got nothing to worry about. I can get my 33's to just rub the shock mounts on my CAGE arms at full lock...barely. One turn of the steering stops would fix it, so I guess I'm just lazy.

H1 rims are 8-lug and have really deep backspacings...so what aren't you telling us? Are you running full-width, 1-ton running gear? Most people weld new centers into the H1 wheels for "standard" off-road applications. What are your plans?

getting them recentered to fit the D44 up front and 9 back. I plan to go 60's, custom width, in the future and adapt them to a 5x5.5 pattern in order to keep the tires and rims. I just returned the 2" body lift for a 3"BL and will probably end up going with a 4.5 suspension lift and cut the fenders to the belt line. Think 37's will fit now?
