Pro-line 1008 Wedge 1.5 Tires for SRB?

[JamesM3081]

I found a pair of unused Pro-line Wedge front tires in my parts bid and would love to use them, but I'm not entirely sure what wheels will work with them. I tried to fit them on 3 piece Pro-line 100-F wheels, but they don't seem to sit well on them. In my research I saw something about Pro-line 107-F wheels, but I can not locate any other information about those. I suppose a SRB or Frog front wheels will also not work well given my 100-F trial(I do not have any on hand to test). Anyone know which wheels they will fit or may be familiar with the 107-F? Purhaps a Kyosho/Losi/AE wheel would fit these?

Any insight would be much appreciated and thanks in advance.

IIRC, #107F is the part number for the 1.5 Wedge Tire.

They are intended to fit the typical SRB (ORV) front wheel, and the #100F is a clone of those wheels (in black).

Thank you information Terry. I just tried installing them again and I feel like they don't sit well, so I'm not sure what to think now. May be that is how they're intended to mount?

maybe rough rider as bigger wheel.

Nah, that's how they are. I have a set of those wheels with Pro-Line waffle tread tires, and they are a similar sort of odd fit. I think there are two things going on which might help the OP:

1. these old Pro-Line tires seem to have an odd shape to the inner bead and a very snug fit compared to a Tamiya tire for example, so it can take some extra force or special technique to get them to seat into all the wheel pieces correctly

2. to help get them seated, it would help to have the correct size bolts (or washers added to the existing bolts), as it looks like the heads are pulling right through the front of the rim in those pics, so they would not really clamp down like usual. The original bolts for those wheels would have had larger heads, with a single slot for a flathead screwdriver.

I assume you are using the center ring???  If so, I'm not sure what to tell you...

Do we know the correct size bolt/nuts???  I have a set of Proline Wheels that are missing the hardware...

I'll have to pull some later and measure, but iirc they were just normal 2mm bolts like the Tamiya version, except instead of smaller more rounded Phillips/JIS cross heads, they had slightly larger diameter heads with flatter tops and a single slot.

Thank you for that bit of information. The wheels have been in my parts box for years as well so probably switched out the screws at some point years ago lol. If you have a free moment, could you post a picture of the waffle treads on the these wheels? The screws, though not the originals seem to clamp everything tightly, but I will get the correct screws too.

Yes, center ring included!

Alright here we go, pictures for everyone!

Firstly the hardware... not in fact 2mm as I had misremembered, I think these are possibly U.S. standard size? They're roughly 9mm long vs. Tamiya fronts which are 8mm (Tamiya rears are 10mm so it seems they split the difference here), but the diameter of the screw is more like 2.5mm, and the thread is different (not metric 2.5mm). The nuts are roughly the same on first glance, but the Tamiya ones appear to be a hair larger overall (fully 4mm), with a smaller hole. And obviously the heads are quite different as well.

And here's pics of my wheel and tire, next to a typical Frog/Grasshopper/Hornet front wheel/tire for comparison.

I also swapped the outer covers and took a second set of pics, which confirmed my suspicion: the Pro-Line wheels are thicker in the middle, with a little different shape to the covers. In fact, the Pro-Line wheels are so thick in the center between the bearings (the shoulder inside is so wide), that you can't fully tighten the wheel nuts on a Grasshopper axle without binding. I can't put all my faith in the friction of the nylock to keep the wheels on, so these are strictly shelfer wheels for me.

It's also interesting that the outer rims seem to still bulge out (although not quite as much), with the PL outer covers installed on the standard Tamiya center piece with a Tamiya tire, and same for the Tamiya covers on the PL center with the PL tire. I guess it doesn't help that the inner profile of the PL tires is more rounded vs. a more direct close fit on a standard Tamiya tire.

Thank you so much for taking the time and effort to make the comparison and providing pictures! I was looking at mine and the Pro-lines having a more rounded inner profile seems to be problematic with these wheels. I will see if I can repurpose these or figure out something else to do with them. May be just keep them mounted as-is.

Again, appreciate your efforts @El Gecko!
