Minimum Lift For 31X10.5 Tires?

killian96ss · Post by **killian96ss** » Fri Sep 26, 2003 1:29 pm

Does anyone know what the minimum suspension lift and or body lift is needed to fit 31X10.5/15 tires without any rubbing issues? Thanks, Steve K.

Post by **HenryJ** » Fri Sep 26, 2003 1:55 pm

Minimum of a 2" Bodylift, if you run "small" 31" tires.

My Geolandars , run on the small side of 31" and I have had no problems with rubbing, other than a little on the inside rear on the frame (minor).

The trick is to stay with the stock wheels too, though.

ok, what would be considered "big" 31'' tires?

BFG A/T's have a very square profile that may tend to rub a little at the very corner of their tread.

Any tire with an actual diameter of greater than 30.5" (BFG's are 30.7")

Swampers tend to be a size bigger, I had 31x11.5 TSLs before, and they were almost a 32" tire

Hey Hobie, i took this off your member page

"If you are looking to put 31's on with no rubbing. The wheel placement is very important. Stick with stock rims in the stock location or after market rims that are to the stock specifications. Also, a 3" body lift would be better too. I only have the 2" body lift. Then just crank the t-bars a little and put shackles on or an add-a-leaf on, and now you have room for those 31's!"

So, are you saying ill have room for 31's since i will be keeping my stock rims then?

that's why you go with a wheel that has 3 5/8" of BS

before my SFA, I ran the stock tirese that came on the truck but changed rims ( i have stock anything ) and cranked up the T-bars to max then turned back down 5 full turns and wiuld rub in tight corners when weight shifted, I believe that 31's would be a tight fit but you would have to run the stock rim or have aftermarket rims with the same offset

Nate · Post by **Nate** » Sun Nov 30, 2003 2:05 pm

see, im going to be running the stock rim like Brule and a lot of other people on this board. If Brule has 31's and stock wheels with no rubbing at all, how much bigger can my 31's actually be to rub?

People that have 31's now, other than hobie ( im not calling you a liar lol ) are you guys rubbing also? i went to the member pages and seen a lot of people have the 31's on stock rim with the add-a-leaf/shackles, and a 2" BL.

Mine do rub the inside rear frame, not bad enought to worry about though. Just keeps the undercoating cleaned off that spot

Nate · Post by **Nate** » Sun Nov 30, 2003 5:06 pm

Ahh, i see. I can deal with rubbing of the frame, but not so much the fender

I just got my PA 2" body lift and some 31X10.5/15 Pro Comp MT tires. I'm going to be putting them on my stock rims. I plan on doing a 1" t-bar crank also. Do I need lift shackles or add a leafs in the back to clear these tires? I want to do this right the first time without any issues, so any comments would be appreciated. Thanks, Steve

nate, i am the only one that has had both stock rims with non-aggressive 31's on and aftermarket rims with aggressive 31's on my truck...i know what both do very well....

remember my wheels are 15x8 with 5" of bs..that makes a big difference...they will rub like crazy on the fender...

and my stock setup was 31" long trails, they rubbed pretty hefty on the frame but didnt touch the fender

it will help, but its not a must..the 1"tbar will make more of difference

As long as they are good 30's (like BFG's) and not the "tiny" 30's I made the mistake of getting! My so called 30's (from Cooper) are actually smaller than the 235/75-15 Goodyear's my truck originally came with!

Nate · Post by **Nate** » Wed Dec 03, 2003 7:57 pm

Brule, when you say "minor" how minor would that be? In hard turning? Does it make your grit your teeth when you hear/ feel it? Also, how to you make your gab guard?

I really want 31's. I have the bfg AT right now but im thinking about getting what you have.

Who on this board has 30's with a picture of their truck that i can see? Just in case i want to go that route. Im putting my bodylift on this weekend. Then im headed to canada for month to play in the snow

( well, after i figure out my tire issue)

Nate wrote:Brule, when you say "minor" how minor would that be? In hard turning? Does it make your grit your teeth when you hear/ feel it?

The only time that I have ever felt it was when the tires were new, and front was compresses (articulated) on a cranked turn. Other than that I can just see on the frame where it has rubbedand never really notice when.

Also, how to you make your gab guard?

Gab guard, I just tell her to "SHAADDAAP!"

If you mean Gap Guards, I just cut some thin belting and attached it with x-mas tree fastners (there should be a thread)

I really want 31's. I have the bfg AT right now but im thinking about getting what you have.

I like them , however they are wearing fairly fast, I pretty sure they won't quite make 40K. When I get some time I'll measure and calculate projected mileage and cost per mile to compare to the AT's Bennie has on his ride.

Nate · Post by **Nate** » Thu Dec 04, 2003 6:27 pm

so, what would be the route you would take? 31's? or 30's?

Post by **HenryJ** » Thu Dec 04, 2003 6:54 pm

Nate wrote:so, what would be the route you would take? 31's? or 30's?

Small 31's (30.5" or under)
Most of the 30's are really close to the same size as the stock (optional) offroad tires , 235/75-15.

The "30's" I got measured 28.25" in height (and they're really skinny too). I'd call them 225/75's if anything! Maybe even 215/75's! They look like that anyway.

Yes.

It is the corner/lugs that rub , so height , shape and width affect the situation.

A 31" 9.5 would clear great, as would a 30" 10.5 , neither exist to my knowledge.

Nate · Post by **Nate** » Fri Dec 05, 2003 9:07 pm

ProComp's Mud Terrain tire 31/10.50 is actually 30.2/10.50 Pretty close. Dont really like the tire though IMO.

I think its also the same for their Xterrain as well. Im not posistive though...

I have a friend who was running 35" Pro-comp AT's

on his Amigo. They are a pretty good looking tire.
I'm afraid that they may wear as quickly as the Yoko's though, and the Yoko's are cheaper.

My Dunlops have done pretty well on treadwear...and traction is great. I have about 10K on them now, and there's still tons of tread left. And at only about $75 each (at Tire Rack), they were a good deal. I've also looked at the Kumho MT's. They seemed better than the Dunlops at about the same price, but they were out of stock when i was ordering, otherwise I would have gotten them instead. My next tires will probably be 31x10.5 Kumho MT's (30.5x10.6 actual size). The Dunlop MT's are 30.8x10.6 actual size...so they're a little bigger. The Kumho AT's also look good at 30.4x10.6 and just over $70 per tire.

I had some Kumhos on my Z28 and was very impressed with them too.

Nate · Post by **Nate** » Fri Dec 05, 2003 10:00 pm

I might go ahead and give the xterrains a try. It will be my first tire so ill have to see. Not sure yet, but ill be ordering my tires monday so i need to make up my mind quick.

Sorta look like the geolanders. Im sure they will wear rapidly though...

tires...hmph

AZS10Crew · Post by **AZS10Crew** » Fri Dec 05, 2003 10:11 pm

There's a lifted Expedition at my work that has those. Nice looking tires. They look expensive though.

Post by **HenryJ** » Fri Dec 05, 2003 10:21 pm

Where are you from, what terrain do you frequent?

There are some disadvantages to a directional tire . You can only rotate front to back.
There is some vibration at slow speeds.

Did you find an X-terrain in the right size? Summit only lists the 31x12.5

The tread on the Geolandar is deeper that most (watch that too) and closer together, which I hope means longer wear, even though the compound is pretty soft.

That was the other complaint I have with the Cooper 9.5x30's I have. They make a ton of noise! And I do drive mine every day. I can't wait for them to wear out so I can get the BFG A/T's I should have bought in the first place.

My 30x9.5's are on 15x7 Rockcrawlers with 4.5" BS and they rubbed a little on the back of the wheel well when turning and flexing. Nothing a litle BFH wouldn't fix though. They still rub a little when turning and flexing a lot (kind of a loose term when talking S-10 IFS), but nothing as bad as before I hammered on the wheel wells.

It should fit fine...the 29" size will help (depending on what the actual diameter is).

I'm seriously thinking about putting 30's on my truck instead of the 31's to work better with my 3.42's.

I parked next to a wrangler at work yesterday that had the same tires AZ has on his truck and the height difference looked good to me

The Dunlops are $76 each at the local Sam's Club, but I'm not sure I need a MT tire. thinking I will go with the Duelers or BFG KO's. Plus I *might* be able to squeeze a 30 underneath where the spare goes.

adrenalnjunky · Post by **adrenalnjunky** » Thu Feb 05, 2004 10:00 pm

31 won't at all. the 235/70 i have under there is almost rubbing my trailerhitch -- that's a 27.9 inch tire, going to the BFG TA KO I think I'll be happier with the 30 in the long run, even if it doesn't make it look as tall.

Retep · Post by **Retep** » Fri Feb 06, 2004 6:32 am

I can't make up my mind on which 30's I will be getting. The 30" BFG AT's just look kind of funny to me. They appear smaller than they actually are. The Duelers on the other hand, look very nice and are rather tall. I am concerned that I might have some rubbing issues with Duelers.

If anybody has 30" BFG AT's on a non lifted truck, could you post some pics.

Do you have the Dueler AT Revo or the regular AT? There are many great reviews for the AT Revo at http://www.tirerack.com/tires/tires.jsp ... A%2FT+Revo. The regular Dueler AT has a more aggressive tread but there are no reviews for it.

I still have about a year of good life left in the stock Goodyears before I must make a decision. I am sure I'll be going with Duelers. AT Revo or not Revo???

Pete

adrenalnjunky · Post by **adrenalnjunky** » Mon Feb 09, 2004 7:46 am

the regular AT is called the Dueler AT 693 - and it being replaced by the Revo. The 693 is a good tire, just a little older.

Be wary of a new tire that is the OEM tire on newer Z71's - it is leabeled a Bridgestone Dueler AT, but it is a highway tire. On the sidewall you will find the marking 693 - II It looks like the Dueler HL highway tire with an AT designation on the side to make Z71 owners feel better about their 40K truck.
