Tire size

I have a 2006 Duramax. Currently running Fabtech 6” lift with 37” tires on 20” wheels. Looking to go to 35” tires on some new 20” wheels. I am worried it may look to small. Anybody have any pics of my set up using 35” tires.

I have a fabtech 6" on 35x12.50x17 heres a picture for reference if you still need it. Did you have to do any trimming for your 37s? I'm getting ready to bump up to those.

I am in favor of using the size my vehicle came with when new. As to QUALITY of tires, well...that's the problem....I've had enough sad experiences with CHINA BOMBS that I suggest you try and find a legit AMERICAN-made tire.

As for tread patterns, as I noted elsewhere...I understand..I "get it"...for some, having a very "aggressive" tread design helps with their personal issues. In fact...that is so common some manufacturers even BRAG their tire tread is "aggressive-looking".

My prejudice is that the best-handling tire is one with a very ordinary "highway tread" design; more rubber on the road.

But what about "off-road". Some of us actually LIVE "off-road"...meaning in my case, about a mile of unimproved roads that get muddy, snowy....washed out....just generally not something the "city folk" are used to, but THINK is fun to have to deal with.

Typically, in mud or snow, those "aggressive" knobby quickly get packed with mud or snow & ice, leaving you with a surface that may not actually grip as better than an ordinary "highway" tread.

I personally have not seen any connection between tire/wheel SIZE, as well as tread design, for determining who gets stuck. Let me qualify that by noting I do not go out looking for big boulders to climb, at least not in my pick-up truck. For that kind of specialized driving, may I suggest the correct specialized vehicle...? Such as a horse, mule, ATV, or better yet..a heliocopter…? I am not competent to comment...we have no big boulders around here that I have a need to throw my truck against.

So - I agree - the choice of tires depends more on what your own personality requires, than actual road/driving conditions.

"We need each other's help to get the best service out of our trucks", but also "having a very "aggressive" tread design helps with their personal issues". So I guess to the OP our fellow buddy here is helping you with your 35" tire dilemma by insinuating you get your Johnson examined.

Don't let the above two "hard-cases" discourage you from contributing. We need each other's help to get the best service out of our trucks.

What I learned in here turned a very disappointing "do-it-yourself" kit into an absolutely delightful, serviceable vehicle. So comment away, and if a couple of sad-sacks feel a need to be disagreeable, trying to take their personal problems out on us, just let it go.

Oh, for those who do not speak German "spiel" is German for "song". Where this poor soul got the idea that I can sing...beats me.
Sorry to the OP here! Poor guy has nothing else to do but post and check his depends. Sorry but it is the truth. I spend more off road time and go through tires like a fat boy does doughnuts. The statement you made about street tires vs off road and yes there are different degrees of tread design that are tailored to mud to sand and rock has got to be the dumbest one you have made yet.

I have already ruined one tire on the ranch and it has a true 3ply sidewall and my 2020 already has 12k on it. Your street tread tires would not make it a day where I have to drive. Just because some of us need to modify our vehicles to make them WORK for our application your idiotic comments are obviously not helpful or correct NO MATTER HOW MANY TIMES YOU REPEAT THEM. Good God Man Get A Life!

To the OP --- my 2020 has better inner fender clearance than the 19 and back models. I have the snow plow prep package and run 35x12.50-20 tires. I fully articulate my suspension frequently (already wore out the intermediate steering shaft ordered on Monday play in the steering) and get only a tiny bit of contact so slight it does not even leave a mark on the plastic inner fender when at a full turn and suspension compressed on that side. With that much lift and the right offset on the wheels you should be ok for MOST of your driving. Still may have to trim some.

I guess they don't use dictionaries in northern Arizona or Google???

Definition of "SPIEL"

a long or fast speech or story typically one intended as a means of persuasion or as an excuse but regarded with skepticism or contempt by those who hear it.

I don't need your sympathy. I could care less what tire somebody wants to run on their truck. Emphasis on the word "their".

As for the aggressive treads you speak of as not very good in mud,snow/ice, what makes a tread with small areas between them better? I have had them pack up so they act like bald tires. Hell, my Kubota tractor tire is perfect in mud-- guess that's why they designed them for the tractor huh? Why would the major manufacturers of tires have tires for winter use with a more aggressive tread if a plain highway tread would work?

I agree with you that the best handling tire puts more rubber on the road but the tire is made to be a better handling tire-- ala Corvette tires. Not gonna get truck tires to do that kinda handling.

I see by your signature that your truck is a 3500-- single wheel or dualie? Those of us that drive duallys everyday can attest that they are not worth a crap in mud/hard rain/cow patties, etc. especially with the OEM tires.

To end this, I was not trying to offend you, just make you realize that , to me at least, everything you post seems to be a diatribe against whatever someone else wants to do to their truck. Lighten up brother, do your truck the way you want to and try to help the rest of us.
