Typically anything between 36 and 220 depending on how rough of a surface you want. I prefer 120.Ok. What does 1 use ? I was told that 1 could use a 80-100grit sandpaper. By grainy u mean ??
Unless the track is rock hard or bites up (or syrup) I usually don't finish Burris any finer than 220g.The OP is on Burris.
What do you mean by plateau finish? I have been using 80 grit on belt sander to put a nice cross hatch in. It doesn't appear to put a real deep groove in but definitely softens tire up from being smooth and "glazed" over. Do you then go over with the 220 to smooth it a little. I run the belt sander at about a 45 degree angle to the tire in both directions using windshield wash as a coolant, blow off with air then add a wipe of prep.Unless the track is rock hard or bites up (or syrup) I usually don't finish Burris any finer than 220g.
For soft tracks that don't build any heat, leaving them course(r) helps build some temp in the tires akin to siping a big car tire. Just plateau finish them so the rough finish doesn't just sit on top the track and take too many laps to wear in.

You're doing fine.What do you mean by plateau finish? I have been using 80 grit on belt sander to put a nice cross hatch in.

So I have three sets of tires on order from you when inventory gets in. Do you recommend your customers do this same type of sanding with your tires on a regular basis? Is that each week after a race night or do you recommend something different? I know I read a post at one time from you that you were looking at the possibility of doing a video series on tire cutting or prep. Is this still in the works? Thanks again for all the info!!You're doing fine.
Yes, I use multiple grits with belt sanders. Plateau finish is a term regularly used when finishing an engine cylinder on a hone. Courser grit, followed by progressively finer grits laid at different angles to take all of the sharp edges, or high spots, off the surface. (ie "plateau" rather than "peak") This also allows the tire to have more surface area in contact with the track and reduces the "break-in" time on the track.
With Burris, you're often on a different set every time you hit the track. They aren't just sanded. They're often also cut on a machine with different profiles depending on the type of surface and available bite for that day.In 30 years of active racing and pittingg, I don't recall anybody ever doing all this stuff to their tires. Not in Sprint racing. All this prep might be good for the first few laps, but by the time you get to the heats and the main none of this prep is going to do you any good. Maybe if you're doiing in the pits between the heats? It might bee helpful for the first lap or 2. I should even say this stuff, what do I know.
You'd be shocked at the differences of a cut tire vs uncut and prepped vs unprepped. Very rarely do I see an uncut unprepped tire faster than a cut with prep but they do have their place and under the perfect circumstances can be faster.In 30 years of active racing and pittingg, I don't recall anybody ever doing all this stuff to their tires.

I didn't hear any mention of cut tires. with quarter midgets, which I've spent some timme with, making them around aand flat was a real necessity. So you're right no argument.You'd be shocked at the differences of a cut tire vs uncut and prepped vs unprepped.

You're right Al. 30 years ago, no one prepped. Life was much simpler for sure.In 30 years of active racing and pittingg, I don't recall anybody ever doing all this stuff to their tires.

Usually with Burris, you refinish them after each race day.So I have three sets of tires on order from you when inventory gets in. Do you recommend your customers do this same type of sanding with your tires on a regular basis? Is that each week after a race night or do you recommend something different?
