Never used them before. Should/Can they be painted, and if yes, what kind of paint (acrylic/enamel)?
TIA

I haven't painted them,just weathered them with pigments

That depends a bit on the kit and tires. Back in the day (early 90's) they had a reputation for poor paint adherence. It's a bit better nowadays, especially with higher quality materials used and the huge diversity of primers available. Getting the molding seams off properly is also a bit of a chore in some cases. Still, with some fine sanding, and a bit of primer they can be painted, which I would recommend as tires in real life are considerably more matt in appearnce.

having the same issues with my Merit Diamond truck and trailer combo. Just ordered and am going to try the new Mission Models paints and primer. They put out a video showing soft rubber tires after being painted with primer and then with black paint and it appears to be a pretty sturdy finish. Going to sample their OD paints as well.

Israel, what kind of tires/which kit? Are you talking about big tires like Anthony's post, or smaller rubber such as on the AFV Club Centurions? I suppose it really doesn't matter as far as painting goes. I've been working on the 2 AFV Club IDF Shot Centurions that I have, and the vinyl parts represent part of the steel wheel as well as the tire part. I have been able to very easily and successfully spray Tamiya paints with my airbrush onto those vinyl parts, and then hand paint the black tire areas with Tamiya. To simulate the terrible damage done to rubber tires on the rocky Golan, I found that cutting and carefully tearing the vinyl tires rsults in reasonably realistic looking chunks out the 'tires'. You do need to be really careful, and start each ' chunk' with a cut from a hobby knife, then gently tear pieces out by hand. Just don't let the tear get into the 'wheel' part of the vinyl. I'll send pictures if you like.

But back to your question, I've had no problem using Tamiya paint on them.

I don't tend to paint them. Unstead I use some fine emery paper and gently sand the tyres to remove any shine. It also lightens the colour.

Some makes respond better to this than others but I've never had any problems with the technique itself.

I have heard other modelers recently complaining that paints still do not stick to the rubber tires.

I use pigments and pastels and have no problems other than sometimes the pastels get rubbed off but that is an easy fix with another application of pigment.

If still insisting on using paint, try rubbing the tires with a bit of automotive lacquer thinner to "craze" the rubber a bit for better adhesion.

I wire brush them first then paintbrush or put pigments on them.

Honestly I'd run away & find replacements for vinyl tires at all costs. Assuming nothing has changed - and I don't think vinyl has changed - after about 10 or 12 years you'll find the vinyl has melted onto the plastic hubs forming a kind-of goo..which melts the hubs as though you'd poured cement onto them - it's the acid in the vinyl. I speak from experience

In 40 years of modelling, I don't recall ever having problems with vinyl tyres melting. I think I had one or two sets split some years after I built the relevant kits (a Tamiya LRDG Chevy springs to mind - and a Dragon BRDM-2) but I can't say I've ever had major problems with them.

Depending on the project I'll use vinyl tyres or aftermarket options, but it's about tread accuracy and quality rather than concerns about the material.

I use a similar technique to John's, the difference being I use steel wool. But, it's the same concept: lightening the color and shine of the vinyl, rather than covering them with paint or pigments.

Guys, thanks a lot, great contribution by all of you!
Resin tires - while they might be the most accurate representation of the real thing -are not an option, as I build (almost) exclusively OOB. I conclude the best thing to do is to gently sand and weather them with pigments.
Curt, I was referring to Takom's 1/35 AML-90, however thanks for drawing my attention to the vinyl parts of AFV Club's Sh'ot, as I'm building this kit simultaneously. I did not pay attention that the vinyl parts are actually representing part of the steel wheel as well! You're right about the damage to these rubber rings, I recall huge chunks of it (sometimes 20-30cm) were completely missing.

Ditto! Wait for resin...it usually shows up eventually for whatever u r building.

I like how my wash and pigments look came out for me on my B1.

Most resin wheels will fit right on your OOB build, you're just saving yourself heartache and BS by ditching the vinyl. No matter what you do to "prep" the surface, the vinyl may simply implode at some point down the line.

Bill , being new coming back into the hobby, could you explain further this pitfall? Is there a failing of materials possibly in the future because of washes used on the tire?

Assuming Bill’s referring to the same phenomenon (delayed implosion) that I reported earlier in this thread, maybe a chemist could help. I’m guessing chloride’s a component of vinyl – or to be specific, of the vinyl tires on an Italeri Opel Blitz bought/made in the late 90’s. I painted the plastic hubs with (probably) a Humbrol Steel enamel(didn’t use any cement, unnecessary) & between those three materials something slowly reacted and “melted” the plastic hubs (and to a lesser extent the vinyl where in contact with them) when I next looked at it around 2012. The Blitz had been in a continuously cool dry concrete garage with no windows for all those years.

Somewhere on one of the forums here a year or so ago I noticed a couple of other modelers had reported similar – whereas others report none...go figure, beats me.

Thank you for explaining that. I will look into this further. I have built a b1 a few months back and will keep an eye curiously on it. Also seeing that I have a few MRAPS I have been eyeballing it's good to know. Thanks.

I have way too many of the old Italeri Blitz truck models, most are probably 15+ years old, with no sign of the OOB vinyl tires or the wheels softening or melting.

No glue was used on the tires (no need) and no paint. I always weather using pastels and the models are displayed on an open book shelf in my living room with little or no direct sunlight exposure.

Just reporting my results.

p.s. Sunlight can affect real tires, perhaps there is a connection there.
