Oops, I think I posted this in the wrong place. So here it is again in the tech section.

Thanks for all the great tech info on the board, I have a 99 D1 I bought new in Dec of 98. Now that I own the truck out right, I trimmed off the bumper end caps and removed the air dam, did the Camel trophy cut on the rear wheel openings (looks like it was meant to be that way). I just had a set of Good Year 245/75/16 MTR's put on this weekend and must say they look killer. Thanks to Disco web, I had already cut the rear wheel openings so I don't have any clearance problems. I did not even have to adjust the steering stops. By the way this truck has stock springs and shocks. My question is, what tire pressure do you run in these on the street. I currently have 45 front / 50 rear as recommended by the tire shop. The truck drives the same as with the dounut tires, only now it wonders slightly on uneven pavement. Would a slight toe out cure that problem? or should I air up or down some?

Ps. As for the Good Year MTR, I like them so-far but, they are not as responsive in cornering as the stock tire. Probably just the diff from a street tire and a mud tire. I'm sure that feeling will go away once I drive on them for a few days.

Also, how do you register (or get an account?) to use the board.

With the bigger tires, you might want to think about upgrading your steering dampner. I have the exact same tires that you have. I upgraded my steering dampner to an Old Man Emu (OME) before I did the tires and I don't have any wander at all.

As far as pressure, I'm still stumped a little myself. I run mine 40 in the front and 48 in the rear. There is a tire pressure chart somewhere on the web, but I have not been able to find it.

Thanks,
Mike B.

Wes, Thanks for directing me to the obvious. Sometimes I can be rather dense.

Mike, Thanks for the assurance that these tires should not cause wonder. As for the steering damper, well, believe it or not, I just had the 60K mile service done about a month ago when I paid off the truck and they commented on how good the brakes looked at 60K, ( Obviously I replaced the pads at 40K ) and the one thing other than replacing all the fluids and filters was the steering damper. I’m sure the stock unit is not very stiff but I’ll bet the rubber bushings are real soft compared to the OME.

Replaced soft stock steering damper bushings with Polyurethane shock bushings and the steering feels tight and true again. No more wonder. I still plan to replace the damper with a better quality unit in the near future. Thanks for the help.

Hey for what it’s worth. I noticed when I drove my truck in the wet grass and then on to my drive way, the tire pattern on the drive way only showed the two middle rows of tread when inflated to 45 front and 50 PSI rear as recommended by the tire shop. I then aired down until I got ¾ of the tread pattern on the ground. This turned out to be 30 front and 35 PSI rear. The Good year MTR’s still don’t have much bulge at all but, now the truck handles and rides like it did with stock tires on the highway. Just food for though.

gabriel-

where did you get the poly bushes for the steering damper?

thanks!

Advance Auto parts, $19.95 GM sway bar link Poly replacement bushing. These are a little thicker but the nuts will squish them right in and leave enough thread for the second nut on the stock damper.

I must say, when the damper was removed, it was really easy to compress by hand. I think the stock damper is pretty wimpy.

I don,t have the part number, but all GM sway bar link bushings are the same. Any hard poly bushing will be better than the stock rubber that rots out so fast from the salt water and air here in NC outer banks.
