Burris tires are very similar to Maxxis in many ways based on how we cure them and use age to tune the amount of bite the tire has, but there are also several differences as well that we will cover below.
>Initial Preparation-
Burris tires will always be faster cut not only to remove rubber but more importantly put the proper profile in place based on the type pf bite the track is going to produce. We offer an in house cutting program and offer (2) different tread depths with a Thick and and Thin version and (2) different profiles with our popular Hybrid Cut and the very well known Round Cut, we will explain each below.
Tread Depth is the amount of rubber checked by the wear holes and we have two different depths. A Thick Tire will be between .065 - .075 and a Thin Tire will be between .035 - .050. The reason for the variance in each is we will cut the tire until we feel the profile is adequate. A thin tire will produce less bite by holding on to less heat over the run keeping the durometer more stable and a Thick Tire will produce more bite by holding onto more heat as well as chemical applied during the week or at the track.
Profile is referenced to the shape and contour that we cut the tire to. A Hybrid cut leaves the tire flatter through the center but profiles the edge but not to the point that it removes any of the lines on the sidewall. We feel this tire has the ability of producing more roll speed as the sidewall can support the tire and it produces less roll over and overall less side bite. Use this profile on tracks with higher speeds, longer straights and higher bite surfaces. A round cut still will have somewhat of a flat center but will aggressively roll the edges which will increase side bite and produce a tire that will make more overall bite when compare to a hybrid cut. Each profile can be cut either thick or thin to further tune what you want the tire to do. All the tires are finished to a 220 finish and are ready for the next step which is outside treatment and scuffing.
>Scuffing-
Just like with the Maxxis, scuffing the tire will produce a tougher rubber and give you options to tune for bite by going older or fresher. Burris tires do not need to be done in as close of an age increment as Maxxis and 2-3 months can in most times be adequate enough time in between sets and I have even seen some items divide their tire cycles up into 3 groups and have success. Using tires from the end of the previous season for cured rubber, buying enough tires at the start os the season to carry them through mid to late summer and then buying tires one more time to carry them through the end of the year, the amount of tires you choose to buy is totally at your discretion. This allows the newer tires to be used when the track is tacky early in the year and cure up for the lower bite dry slick portion of the season come summer months and then back fresh again for the fall.
>Outside Treatment
Obviously its very hard to say what will work in every situation but we have learned over the years that there are typically two type of track conditions that races will encounter, dry slick and tacky, and despite what you may think they take a different preparation based on the bite these conditions produce.
A tacky track will generally produce the most bite and normally newer tires will work in those conditions with the High Bite being the go to outside weekly treatment to condition without softening the rubber. Medium Bite can be used as well if you desire to slightly reduce the durometer as you are conditioning. Both HB and MB can be used at the track cut 50% with Acrysol and the Fire works very well when you feel the tire can makes bite units own after a few laps and all you need to do is help the tire build heat quicker without the risk of locking it down.
A Dry Slick track will in most cases produce less bite and a cured tire is desirable as the tire will be tougher and harder and generally speaking a more aggressive prep trackside only will work the best like Extreme Green as a topical fire off prep only. EG can also be cut with a drying agent like Acrysol or even Acetone to make it less aggressive and act a drier firing agent with less softening per application.
>Post-Race Maintenance-
Regardless of the tire or track being ran on surfacing a tire needs to be done for all tires ran to keep fresher rubber to the top, the tire open and receptive to treatment and to take off any graining or fuzzing that may have occurred if the tire was ran on an abrasive track or had aggressive prep applied. Make sure to surface as smooth as possible and not to get the tire too hot, if you notice any shiny and or sticky layers left on the tire let it cool down and surface again. A dull, smooth finish is what you want when your finished. For tires that are in circulation and were wiped with conditioning prep, you can re-apply again as needed to get the desired feel back in the tire, if tires were ran and were designed to be tougher and cured you can just surface and let sit until the next time you need to run them.
