Hey all. Does anybody here have this kit? I was wondering about the size of these tires. Thanks, John

John, I have one here I bought years ago when it was a current issue, from what I remember the tires are crappy, I'll dig it out, measure & take pics for you.

I bought this kit thinking that the tires would be useful the 1:1 box art is deceitful as to what's in the box! Here's a few pics... with rims, clockwise from upper left...optional to Sonoma kit, OEM Sonoma wheel, and 8-lug wagon wheel from AMT 1984 GMC (Fallguy). This shows how out of scale the 1/25 wagon wheel is! very weak tread and lame sidewall lettering... and the specs... overall diameter---1.5" inside diameter---.75" treadwidth---.437" overall width---.578"

Thanks for digging them out for me Jeff.
These tires appear to be exactly the same as the 1/20 tires that came in Baywatch and stock Toyota Lindberg kits. I am guessing that Lindberg used them in all their 1/20 truck kits.
Like you said, not the greatest but good to know we have another source for them. I have seen the Sonomas going pretty cheaply on ebay. John

Gee, I was going to cast them......maybe not worthwhile?? Alan

Alan, you should have a smaller sized Super Swamper from Rodney that could be very worthwhile. someone doing the Yokohama's from the Tamiya kits in the U.S. would be nice too.

The 1/20th Jeep Grand Cherokees used a Goodyear tire that was a street tire, looked more like a 1/25th scale semi-truck tire. The AMT Fall Guy wheels are used in the reissued MPC Jeepster Commando kits but they were originally used in their 1/20th scale models, so that's why they fit. AMT/MPC also used 1/25th scale wheels/tires on their 1/32nd scale kits too.

Gee, I was going to cast them......maybe not worthwhile?? Alan You know, I almost have to disagree. I am wondering how much longer we can get them (cheaply). Ironically I have been hoarding them, I really like the size, just perfect for a modern racer. Too bad you cannot fix the tread. Sebastien brought up a question I have been meaning to ask all you Master-ers. Any thoughts how to master a tread pattern? I have built many vector tread patterns in the computer (in differing tread widths) and they can easily be made to fit a certain diameter tire. The thought was to have a sign company use it to cut thick vinyl, stick the tread onto the master tire, then create a mold using it. As of yet I have not found one that wants to try such a small decal. Have started researching CNC but have not gotten into it enough to know if that is an option. Rear | Front | real tires

when I do a tire master I first do what you do on cad drawing. ( I use autocad ) after that I print it on a 0.020 styrene sheet. and glue it onto my bare tire.and now strat the job by engraving ( remove )all plastie between the threads. yes it's VERY long but WOW the result is incredible.
the idea is good to take it from a vynil company. where it's freak me up is ... if the lue use to stick the vynil onto your bare tire will be compatible with the silicone took to made the mold. it's happen to me long tiome ago when I was a young caster. took +- 75 hours to do a master and f#@$tup everything by an incompatibility between onoe of the glue I use and the silicone.
the result was... it never cure. and when you try to remove an uncure siicone.. GOOD LUCK because you need to remove ALL of it. forget 0.000000000001 oz of it and the new one will not cure too. so... it 75 hour lost + the time to remove it the first time.
I learn by yhe hard way but I can tell you now... it worth the money invest at this time.
yours

I'm currently working on masters for the 1920's Non-Skid tires.(Remember them?) What I'm doing is photoetching the tread pattern & then wrapping it around a blank I machined. This was the technique used by Etzell for all his tires in the resin kits he made. I can do my own artwork, etch & machining so I should be able to produce any tread pattern. Any suggestions?

Hey Alan, that sounds neat! Would a photoetch overlay produce a deep enough tread though, like a 1:1 off-road tire? I was thinking about kinda the same principal, only cut the tread pattern by hand from styrene, since the tread pattern repeats, only a small section would have to be made, then reproduced enough times to cover the circumference of the blank, then reproduce the entire tire once completed. Sounds like alot of work! If something like this is doable, the must-have tires would be... 1. BFG Krawler T/A... 2. D. Cepek Crusher...cool bones tread! 3. Ground Hawg radial...we have Revell bias ply GHs to work with, but the tread isn't all that deep & since they're directional tread, lettering only appears on one side of the truck! Gotta revive this tire since the Denman plant is local to me & just closed last week for good

Hey Jeff: The deepest I can etch is .01" or 1/4" in 1/25th scale. This is probably not deep enuff for most off-road tires. But I can see if it's possible to go deeper with softer metal.

Any suggestions? Alan, of the trucks in our magazine a vast majority have BFG Mud Terrains... racers to show trucks to daily drivers. If 1:1 is any indicator, I would think BFGs in 30", 33", and 35" would be useful. And a realistically sized, visually loud tire like a Thornbird or Bogger (but you already have that one right?) John
