Tires I'm going to get measure 40"x16"x16". Where I wheel the maximum width is 80". I don't want tickets. What backspacing wheel will I need to be legal? I don't want to have to narrow the axles to achieve this. 77 K20 is the rig the wheels and tires will be going on.

where the hell are you that you'd get a ticket for wheeling a rig over 80" wide?

 

[sterlingfire]

Do you have to pull your mirrors in too? I'm sure that puts you over the 6'-8" mark.

Do you have a tape measure? Can you do simple math?

Lets assume your front axle is 68" wide. Lets also assume that your tires measure an actual 16" wide.

If you have a wheel with zero offset (centered), your overall width would be:

axle width + tire width = 84".

Welp, that puts you 4" over. You need to come in 2" per side. That means your wheels need to be offset 2" towards the vehicle centerline.

Since you didn't mention the wheel width, here is what you need to do to figure your backspacing:

(wheel width / 2) + offset = backspacing (towards vehicle centerline)
(wheel width / 2) - offset = backspacing (away from vehicle centerline)

Thank you for the formulas. That's the kind of info I was looking for.

Most wheeling areas around Puget sound state maximum vehicle width of 80"... Gives the reason for DNR to look and find things... They are dicks. They will use a tape measure if they feel the need. Will also check if you actualy have a spark arrestor on motor cycles and quads.

I think I would be looking for some narrower tires. 16" wide on a negative offset rim isn't going to give you much room between the tire and frame. Not going to be able to turn very sharp at all.

Unless of course it's a bgt.
Most dnr officers are trying to do their jobs, and checking motorcycles and quads for spark arrestors is normal practice around my state too. Don't want to use one, go ride on a track or private property. Then you can do what you want.
As for the width, I'm with the post I quoted, get narrower tires, interco makes a 38" tall tire that is only 11"wide. It's one of the tsl's, not sure which one.

 

[dman1049]

My thing is the narrowest 40" I've found for 16" rims and at $350 a piece is hard to resist.

DNR checks for spark arrestors because they are tree growers and dont want the trees burning up before they are turned into lumber. The USFS has 80" width restrictions at Evans Creek Orv trail system, where else is 80"? A stock Dana 60 front is 80" at the widest piont, 12.5" tire on stock chev wheels will make you the right width. Not sure if a 16" tire would clear turning with Inset wheels.

Tahuya state forest

It was 96", did they change it?

 

[dman1049]

Just word of mouth from people who have done it longer. Maybe it is? Do they actually enforce it at Evans creak?

and ask, he is "in charge" of the Tahuya area. I only know of 1 vehicle that has been turned away from that trail system and it was basically a monster truck. Evans Creek is enforced with goal post gate keepers and LEOs on quads. The trails at Evans are single track trails that were made wider with flat fenders, trails at Tuhuya are mostly logging roads. The two trail systems are manged by different agencys.


Evans top, Tahuya bottom

That's a cool rig. Evans creak looks fun. Ill have to come up with a way to keep the truck below 80" tho. I'll find out when I get the tires on

Washington state is a super gay state when it comes to this crap. There are some designated orv areas that are 80" width restriction that they do ticket for. Going wheeling in washington is a huge hassel and the rules make normal honest citizens just trying to have fun, into criminals. I can't go to evans creek orv park because my rig is 85" wide. But you can go to elbe hills, funny/moon rocks, and a few private places if you are wider.

 

[dman1049]

"Elbe hills, funny/moon rocks, and a few private places"...can you tell me where these places are?

there is this magical machine out there called "Google"....you may want to try that and see what you come up with

Cause Google will tell me about private wheeling areas...

 

[DMANbluesfreak]

It's private land you plutard, not private wheeling. Just like the house you live in (unless you live in a box, which may be a possibility) is likely on private land. Just because it's private doesn't mean you can't pay to get in.

Let me google that for you
