Cummins + Lift + Tire + Wheel =

[Greguw]

Hey Guys , Just got the 1990 Suburban V2500 in the shop , just sold the motor last night .
I am in the process of ordering parts ... I am still torn between the 6" or 8" lift . I am doing a 1" body for clearance for the cummins and body bushings while I am there .
Tires either 36" or 38" , I was talking to NTW about radial ground hawgs , seems there discontinued , he also said there un sure if Interco is going to produce them .
I don't want want want to run a 16.5 so that either puts me into a 15 or 17" ... I am not sure on the back set with the dana 60 rears, I did see a few postings on the 2.5 BS on wheels for the 15" .... How far will the wheels hang out with a 2.5 BS ?
Besides Eaton wheels are there any other companys producing steel wheels ... aluminum does nothing for me .
I would love to go 8" and with the 1" body thats going to put me around 9" of lift , Cops in my area can be dicks ... with the gearing and cummins I think I could run a 40 tire .
Another concern is weight ... this truck is going to be heavy .
Not sure on the tires right now , I did see a lot of tires rated at 3600 lbs , radial Swampers and Procomps .
I may want to run a 12" wide wheel for more stability ... any insite on that would be great .

Thanks guys

Man I'm taging this love to see a good saburban build. And yes u can run 40's on an 8 inch lift my buddies got one on his property running 44's on an 8. Get the pics coming. Sounds like its going to be a killer rig.

For 40's stick with 6" total lift
If you want to go to 44's then go bigger(maybe).
I believe that you have the older style sub (90') with the solid axle? I would definitely look into putting a D60 up front. Do it at the same time as the engine swap so you don't end up doing anything twice. If it a street drive tow rig I would stick with 37's and 4" of total lift.
my 2 cents Jack.

Yes it is a older body ... I have a new in the crate military dana 60 and 14 bolt with locker and 4.56 . I'm not a young pup , ever the old lady was say I'm a little too old for 40's ...LOL
As I said I am adding a 1" to the body which just gives me a little extra room when I stuff the 6bt with the dodge Cummins NV4500 with all the up grades and a 205 .
I'm leaning toward the 6" lift ... That will put me around 7" of lift .
Where I am at now is tires and wheels , Not sure what the stock back set is ? ... I am looking at either a 16" or 17" wheel . I'm not even sure what tire to run ... this truck is going to be 75% on road and 25 % off .
I was looking at the Toyo MT , they have a great load rating on the 37x13.50 -17 ... there around 3800lbs
.

Toyo tires are awesome. I sell them all day long at work. I'm even running them on my 2wd lifted furd 150. Have had the truck sunk to the doors and they grab like no other and have gotten me out of some places a 4wd would have gone through.

the cummins 6 cylinder dry with no accessories is ~1100lbs +/-... A 6bt +NV5400 =~1700lbs dry

so make sure you are prepared for it. box the frame, re-enforce, etc....
can the D60 handle that?

dry weight is just over 900lbs, as installed is 1100lbs. The truck will handle the added weight no problem.

should of read with accessories


~900lbs w/o accessories(dry) ~1100lbs fully dressed(dry) + the nv5400 (350 +/-)

NV5600 = 465lbs (+/-)

I love my toyo M/T's, the 37x13.5x17 are rated for 4300lbs btw. They are (IMO) the best M/T tire.

[Greguw]

The Toyo M/T's, the 37x13.5x17 is the tire I am considering ... The 13.50 may be a little skinny on the sub , especially if I go with a 8" lift ... But if I go with the 6" that will be the tire .

Hell you could run the toyot mt in a 385/70/16. Witch is 38 inches tal 16 inches wide. I'm considering those for my crawler.

[Greguw]

What are you running for rims with 37x13.5x17 ... I seen a few procomp rims that were rated for 3400lbs .

My buddy runs these on his 2001 7.3 psd with built 60's, tons of motor/tranny/exhaust/tuning, much better on the road than the nittos they replaced, dont know about wear yet.

My tow rig is now running the new(ish) goodyear duratracs not sure what sizes they offer but mine are about exactly 33x12.50 and i know they go bigger, supposed to be the best m/t ever made and these ones sure seem like they are the best truck tire ive ever had, pretty damn aggressive looking tread too, would really like to try them in the desert.

Kevlar mt/rs or duratracs would be perfect.

The D60's handle it just fine in the Dodge trucks.
I second the frame reinforcment also.

I'll be running 35x12.5r17 rocker radials under my cummins. 91 v3500 crew with the cummins swap. They are load rated E, so we shall see how they fair. Rims are 9" wide.
