PR good.. Power1 WAY better. may all your prayers be answered! Posted in your other thread on the other site too.. LOTS of fast guys (and gals) going VERY FAST on the new Power1 tires. INFO ON NEW Power 1 tires...POWER 1 tires (info)FRONTSall the DOT 17" fronts are MULTI compound and run 30psi cold. (just like the C). There are three (3) fronts to choose from. THe A and the B are SLIGHTLY more rounded but IS trianguilated. the V, the most triangulated or pointed of the 3 tires. A and B are slightly less triangulated than the old C front but apparently nearly exact same height. According to Michelin, the A and B would be the most popular tires and are 5 ply tires. A- 9.48lbs, 605.4mm diameter and is the softer compound, used for when ambient temps are below 68F. compounds would be 4/8/4 with the 4 (softer) would be the entire contact patch at full lean.B- 9.48lbs, 605.4mm , slightly harder than the A, and used when temps are above 68F. compounds would be 5/8/5 with the 5 slightly firmer than the 4. V- 9.92lbs, 606mm, however is 4 ply (not 5 like A and B), and is more triangulated almost "pointed" with a 5/8/5 compound. REAR TIRES. -all the180/55 are 639.5mm in diameter, 13.73lbs, are 4 ply and multi compund (35% of edges is softer so 35%/30mid%/35%) -all the 190/55 are 652.8mm tall. 14.77lbs, 4 ply and multi compound. -the "A " tire edges of the 180 and 190's would be a "4" (soft) compound edge- the "B" edges being "5" (not as soft as 4),-THe "C" REAR will be an endurance type tire with a "6" type edge -ALL the middles of all the tires being a "9" compound (hardest).TIRE WARMERS: as per Michelin, for COMPETITION (not street tires) put warmers at 176F for 30-40 min before use for FRONT AND REARS. DO NOT leave on for more than 90 minutes ever. If guys find something that works better please let us know. WEAR: when the rain sipes are gone the tires are designed to STILL WORK ! so dont rush to change when the rain sipes are gone. The tires are designed to loose the rain sipes to become a "slick". There WILL be NEW series power1 150 and 160 rears, as well as 110 fronts but are not here yet. There will only be an A and B but front and rear are multi compound.The slicks are out right now! the old 46a slick 17" front is still available but will be labled "Power1" like the DOT tires. NEW 16.5" - 3 choices front and rear like the DOT line. MULTI COMPOUND (still hard middle, but one side is softer than the other, softer side has a "-" and harder side has "+" Track day/sport tire are all 3 ply and are multi compound front AND rears. Front is 4/8/4 and the rear is 3/7/3..so may get too hot with fast riders. There is less area of soft sides on these, 75% of the middle is 7 or hard, with only 12.5% on each side being the "3" or softer compound.
Will Michelin have some better slicks this year? According to my Michelin guy the slicks in 2009 were no better than the Power Ones so I never tried them, but he said they should have something new soon. Any info?
