Sagged tires are the way to go!

Those that disagree and feel they are under-inflated, well I feel sorry for you!

Get your eyes checked!

I was once a Tire Technician and multiple ASE Certified Technician in the 80's and 90's. Tires with a vehicle's load on them WILL show some type of bulge, unlike the kits toy-like performance, sagged tires are the best.

Glad I see that a least one man on here is intelligent!


Oh, and nice report Kevin!

I MOST HEARTILY AGREE!!! Some aftermarket companies tend to exaggerate their resin tires' "out-of-roundness" by "flattening" the ground-contact surfaces a bit too much, and add a bit too much "bulge" to suggest "weight". In my own experience, I find that DEF MODEL, D-TOYS, and HUSSAR keep this exagerration to a minimum, giving the modeller the most realistic appearance.

Heavily-sagged tires can be appropriate for vehicles with inflation control that you're showing in a situation where they'd be dialing the inflation down for better ground contact, but that's a specialized application. Even heavily-loaded vehicles don't show the degree of sag I've seen in some sets with normal inflation pressures.

By the 1980s and 1990s civilian tires were almost completely radial ply construction. Until the late 1960s very, very few were, bias ply construction being dominant to that point. The two tire types behave very differently. Bias ply tires have little bulging while on radials it is significant. In fact, US Combat-type tires were specifically constructed with extra-heavy sidewalls to give a run flat capability and thus had virtually no detectable bulging. On the other hand, Military Desert tires intentionally had weak sidewalls so that they would bulge when the pressure was reduced to increase ground contact area and reduce ground pressure. All tires will have flat spots though, but again, the size of it depends on the construction.

One should also be wary of restored vehicles as tires made for the collector market often do not follow the same construction practices as the originals. Instead, they give the *appearance* of the originals with an internal construction that gives a lower purchase cost and better fuel economy in the typical highway use.

So, the really "intelligent" man realizes that technology changes to meet design requirements as well as evolving over time, and what is right for 2,200 lb commuter car in 2014 might not be what was used on a 30,000 lb cross-country military truck in 1942.

All the after market stuff for the Goat coming out lately is making the kit very appealing to me. On an off topic note, an M47 update set has been listed for future release on DEF's website for some time, does anyone know when this set is coming out?

ALL I'm saying is that the kits plastic/styrene tires or even the vinyl tires shows NO FOOT-PRINT or the vehicle's load! Just a round circle! LOL

Sagged tires, whether historically correct towards the correct tire construction or not are more appropriate then those mentioned above.

It is always left up to the modeler how far he wants to go...

... just like individual liked tracks or the single one piece vinyl tracks.


The Tamiya Goat kit doesn't even have a complete tire! Just look at the profiles on picture number 4: http://armorama.com/news/16559

If I had only X amount of money to spend on aftermarket gizmos for the Goat... I think I could get a lot more bang for my buck by spending it on something like a soft top for the cab and trailer... Rather than spending limited resources to get a tire bulge that I could simulate with a little heat and a few techniques.

Is it me, or are some of the aftermarket companies selling solutions to problems that aren't... I've seen lots of PE sets where the kit item is better representation than the PE part - it's like sometimes they make items just because they can ... well correction - I guess they make items because suckers like me are willing to pay for a solution to a problem that doesn't exist!

What the GOAT really needs is:
1. Soft tops for cab and trailer
2. Antennae mount and radio
3. Lifting rings in the front corners of the tractor
4. Correct the mismatch of time eras...
a. The present turn signals are a later version though the engine cover is the first early version.
b. Solution - provide the old fashioned turn signals and/or new version of the engine cover.
5. Provide the winch lever that is so clearly missing
6. Provide side marker lights/clearance lights for the front fenders.
7. Replace the hideous Black Out Drive Light's protective bracket that is supposed to be just stamped sheet metal but in plastic scales to a 2 inch piece of cast armor!


And then of course all the tiny items, but those above are the ones I'd expect should be standard in the kit.

I'm afraid that some of these new kits coming out are based on vehicles that are still around today in enthusiast hands and often are modified or missing things that would have been on the vehicle as seen in the proper era. I think that's what happened with the modern turn signals and old style engine cover.
