Ive heard 33's are sensitive to prep. Does this mean they need less prep to work than other tires. What would be a good starting point for a mid to high grip track for weekly prep. Also Can the same set b run all night or need at least 2 sets. Im sure more sets is better but some of us are on a budget.
First remember to figure out which 33 is fastest for which ever track someone needs to prove that, but you still need to prove what works for you as it may vary slightly, and there are NUMEROUS options which most guy's over look.
Yes 33's are more sensitive to prep, especially AGGRESSIVE preps, however that does not mean in general always less prep, track condition dictates that. I had a guy explain it to me this way so I'll do the same, think of that 33 tire as a cake with thin layer of frosting with 33's you want that prep for 90% of the tracks to be the frosting, IF you get that prep to far into the tire where it would make the cake to moist they fall off ( yes there are a few softer tracks that stay moist slick it can be deeper ) Because of this the best guy's on 33's around here NEVER wipe a 33 through the week or roll them in prep, (Again maybe 1 set for a certain track ) they prep If at all at the track only, I've seen with 33's provided you have the right tires,with right cure time along and put them on at the right time NO prep ( Simple Green only ) will provide the best lap times, PROBLEM is to prove that there are so many options with not only Tire, Year, number of heat cycles, and Profile of various cut's that could end up 1 of 20 sets, this is why when someone faster shows up you need to pay attention walking around the pit and at the grid, one can learn a lot while NEVER asking any questions, look If there B 33's, SS 33'A, The Date Code, Thickness of the rubber, which cut IF cut at all, are they coming to the grid with wet tires, are they always last rushing to the grid, Do they ever check Air at the grid, learn as much as you can without asking questions, Don't be afraid to ask questions as well, worse they can do is not answer or lie to you BUT if you already looked and know the year and say the cut is round you'll know IF they lie to You, IF they do don't trust any of there info. AS far as running them all night, That depends on the competition IF you get away with it or not, You would NOT get away with it here at a BMS Series Race, even IF you only ran them to qualify 3 laps, BURRIS tires with out last any tire as far as number of races HOWEVER re-running them on the same day you will loose 1 to 2 tenth MIN. Plus back to the sensitive part IF you EVER wipe an AGGRESSIVE prep on a 33 because the track you were at required it, Then you go to a Track that makes High Grip that would NOT require that aggressive prep, That same 33 will never perform at MAX potential speed, Does not matter if it's a year later. This is just some of the info with 33's I could go on for another 2 pages SO I'll stop for now and will give more info later as guy's ask questions OR I'll just put it out there, ALSO this is WHY NEVER sell any of your 33's until cords are sticking out, UNLESS you never intend to go to different tracks or you quit racing.
NOW to answer your question If by saying Mid to High grip track I'm assuming Mid to Good grip for qualifying or heat racing, then High grip for race, and Indeed your definition of Mid to Good to High is same as mine, A 2018 set of SS 33 A , with numerous heat cycles on them, and flipped on the wheels, NEVER wiped with prep or If ever wiped was HARD Track base prep only, Depending on how early that class was in the line up would dictate If I tried round cuts or Flat cuts, Early Round cuts, Later Flat cuts, punching around 57 to 58 Duro scrubbed with Simple Green only would be a good choice, Then for the race A 2016 or 2017 set of SS 33 A , with Numerous heat cycles, flipped on the wheels, NEVER wiped with prep or if ever wiped was HARD track base prep only, Flat Cut's punching 62 to 64 Duro Scrubbed with Simple Green only would be a good choice.
Enough for Now !!
