Axles & Tire Size ???

[dirtgrip]

Looking for a little info-what size tires do you run? What axles & mods are done to them? What do you think is max for your axles offroad if the tires were true to size & the offroading was 4 or 5 rated trails?

37" tires work well, 42" works even better. Definitely the biggest you can afford and CrMo throughout. I have a D30 30 splne front and D44 33 spline rear. The rear is every bit as strong as a D60 minus the ring and pinion and the front is approximately equal to a D44.

D60s front and rear is the way to go for serious trails. 78-82" track width is where you need to be and 104-110" wheelbase will allow you to run the 5.0 trails without much winching.

There you go.

by track width, are you talking about edge of tire to edge of opposite tire?? just wondering i have no idea! thanks

[xFallen]

No. Vehicle track is defined as center to center. I mis-typed previously. I meant 78-82" outside width.

Search and research. You'll find this has been hashed and trashed countless times. There's no one right answer but the above guidelines are definitely what works for serious trails in AZ. For modest runs 4.0 and below, run whatever you want because it matters far less.

Yes outside to outside and HP plays a big part .Most 5.O trails fnd you wedged in or take bumps to get thru but 70% or more is driver .If not willing to break hard parts build bigger axles to begin with .Build a 30 and 44 your saving big dollars but leaving the door open and if you plan on running 5.O trails don't bother because in less than 2 years you'll be doing it all over .Or buying stock in Alloy USA .

Track width is measured center to center.

I looked at this post and decided not to comment because 4+ trails are beyond me personally. I do think that my D-44's will do the job but only Jeep gods like Barry run these trails on 33" tires. :eek:
When I go to 35" tires, I will upgrade to Chromo axles and 4:88 gears, Just a few thousand bucks, but who's counting?
Then, with some good spotting, I will be trying some of the more difficult runs. :)

Most of those trails were opened on 33s. Lockers, a winch and good driving is what you need, plus an understanding that body damage is not carnage.

Thanks for the replys.I'm just trying to find out what level of AZ trails my Jeep can run without serious carnage.I'm still on a stock wheelbase & width.It's a TJ with a 4.0,AX-15,231 with 4:1,4in SA lift,1in BL,& 37MTR's(may go to 36 Bias IROC's).The axles are Terra(oh no)CRD HP60's with lockers,discs,35spline chromo axles,with 5:38's.I know HP isn't as strong in the rear but it helped a LOT with driveline angles when using a bellyup skid on a short wheelbase.Here is a link for the axles:http://www.teraflex.biz/pages/product_results.php Search crd
I have never run AZ trails before so I'm trying to get an idea to what is possible so I can plan a trip.

IMHO, there are not many trails anywhere, (AZ included) to which decent driving skills and your vehicle should not be able to tackle with little or no body damage.

Sorry I should have specified that body damage is not a big concern-although I would like to avoid it.I was more worried about the driveline holding up.

When I was a kid helping my grand dad run farming equipment, I sometimes got a bit rambunctious and something would bend or break:eek: :p :o ...

It's been a VERY long time ago, but I can hear his words like it was yesterday...

"Don't take no brains to break it son... This job can be done with this equipment with just the SLIGHTEST use of whats between your ears":eek: :o :p :D ;)

Obviously, what he was alluding to is operator style has a LOT to do with how it will perform/survive.

Personally, IMHO, if there is a weak link I believe its your tranny, but I truly see absolutely no reason to think you should be breaking a bunch of stuff... But then again, your driving style and the thickness of your wallet will help you decide that soon enough...:D ;)
