20" tire/wheel question

tugger · 07-28-2008, 09:32 AM

Would I be able to run a set of 20" wheels fitted with 275/60/20 tires without having a rub problem?
I do NOT want to do any trimming on my truck.
The tires would be a road tread design for summer use. So, no big lugs to deal with.

I'm running a 275/65/20 which is 34.2" tall and it's on a 20x9 Incubus Wheel with +20 MM Offset, I had to do a little trimming here and there and raise the torsion bars 1.5" from stock to make them work. I think you'll have to trim a little off the bottom of the inner liners and you would definetly have to turn the bars up just a bit to make them fit. A 275/60/20 is around 33" tall.

the 275-60R20 will clear even better then the other sizes mentioned above..just make sure you get a wheel thats only 8.5-9" wide and with a 4.5-5.0" Back Spacing.

Tyreboyz reply sounds right, Whats the exact year make and model of your truck? I am see what our guide says. Also do you know the specs on the wheels you are looking at, width and offset/back space?

My truck is an '05 Silverado 2500HD Ext. cab (Duramax of course!) with stock suspension. I currently run Cooper Discoverer S/T 265/75/16's on factory alloys and I have 1" of clearance in the front.
I have no problem raising/leveling the truck with the torsion bars but don't want to get too tall as my girlfriend is in a wheelchair and my back is not getting any younger. I definitely do not want to cut/trim anything.
*** My truck came with a set of green keys still in the box. Why would I need these to level the truck? Can't I just tighten the torsion bars as it is or is that too much strain? Won't I need to get the front end realigned after a torsion bar adjustment?
I am still trying to narrow my choices down yet on wheel choice so I don't have any definite offset specs to give you. I was leaning toward the Incubus Grim 505 but the distributor told my local dealer they are discontinued.
Other interests: American Eagle series 64, Alba 888, Ice Metal IM898, and Venti VE92(back ordered).
I am figuring on a 20 x 9 or 20 x 8.5 width and was considering a 275/60/20 Cooper HT+ tire. I like the look of the 20" set up on the Dodge trucks and that's how I came up with that tire size. However, I am flexible on the tire size. I would like to pack in as much width as I can but at the same time I don't want to get to too small of a sidewall height like the rubberbands some of the cars ride on as I want to keep my fillings in my teeth. Pimp mobile it is not. Even though it's a 3/4 ton truck, I am after a little more of a "street cruiser" look rather than the rugged off road look.
I sure appreciate the comments so far. I helps immensely.

Ya the keys are ment for adding a inch or 2 and you can still raise the torsion bars. But, for what your doing raising the bars will be fine. Also, you will still need to get a alignment after raising the torsion bars. The 270 is shorter than the 285 so I'd say they would make it fine. The only part it could rub in is the bumper valance.
