Markal 51421 Tyre Marque Tire Marking Crayon for Temporary Tire Marking, -20 to 130 Degree F Temperature, 1/2" Diameter, 4-5/8" Length, Yellow (Pack of 12)

I use these at work to mark cars parked longer than allotted so I can’t review this for what it’s actual purpose is, but I will say these mark tires and asphalt very well, super bright and very clear. Only qualm was the packaging broke during delivery so all the crayons were loose in the bag. Maybe a little tape on the box next time? Good quality though, they don’t snap in half when you use them!

They don't paint as brightly on a tire as the Markal B, but they are finer and don't seem to be as mushy as the Markel B..just gotta add a little more pressure and not mind the duller color.

It is what it is, a crayon to write of a variety of surfaces. Does tires so much better than chalk. Stays of surface for long time. Great to mark which tires go where when you have an extra set of tires such as winter.

Works well. Only problem is about 103 Degrees they will start to melt & in Arizona 115 degrees in the summer is common! I will continue to buy anyway as they do the job well. Just in the summer can not be left in heat even if covered. They will not melt if in your pocket.

These work well and will mark a wet surface. My only complaint is that they are pretty brittle so they will snap if you put too much pressure on them. I would buy them again because of the price.

I use these to mark my winter and summer tires so I know which side of the vehicles to keep them on and for rotating them from year to year. I rotate only front to back, which seems to work best for me. The main criticism I have for these is they could be a little softer. They would leave a more visible mark and would be less prone to break when shipped. One of the crayons was broken when I got it. Otherwise, I like them.

These tire marking crayons worked great. I used them to mark the positions of my summer tires on my car before I put them away in storage for the winter. I marked onto the tread and the marking stays good enough that it won’t just smear away, but it is easy enough to wipe away with a little bit of elbow grease. I’m never going to be able to use all 12 of the crayons, but the price was low enough that it’s okay.

Works great. No issues. Read complaints about breaking and crumbling. Mine showed no sign of this issue. I also keep mine in the house. Maybe cold temps or rough use can cause them to break. Worked well on tire rubber but does not remove easily. But who cares, mark inside tire sidewall.

My Recommendation: Not to buy.You would think that there isn't much to review about tire chaulk. However, there are differences. This one keeps breaking when writing on tires and I am not even applying a lot of pressure.

This is more like a wax based product. It is extremely hard to take off tires and will not rub off easily. Do not use this if you are a bylaw officer as it will never come off

Cheap markers, break easy. First one crumbled in my hand as I took it out of box. Second broke as soon as I barely touched the tire. Used nub to mark tire, gotta press pretty hard, not good when so easily broken.

Fonctionne à merveille. Fait exactement ce qu’il doit faire et pour la raison que c’est supposé faire. Bien identifié les pneus et proprement
