Bridgestone R10 DOT Part 2

—  front tire x 17 TYPE 3

AMBIENT 98 degrees F

BIKE 2009 R1

Having optimal tire wear in the test by tuning chassis and using Bridgestone’s recommended hot it was time to experiment with pressure changes only. I had that the right side of the were balling up more normal, (those are slow type corners requiring throttle or only slight and that normally means pressure is too low creating accelerated

In addition my initial response was this new R10 was very close in (therefore feel) to the Pirelli DOT. For my own personal tastes, I a tire to hold its shape hard acceleration and heavy so I go far beyond recommended pressures I find what I need. In the of Pirelli’s I ran 38 hot in the front and 34 hot in the rear on my at race events.

Remember that in testing you to find both bad ends of the and then move in on the target

For session 1

—  hot tire after 30 minutes on the warmers set at 40 hot front, 38 hot rear. The tires all bumps, even the smallest and the tires suffered from over high speed While the bike could be the risk of deflection and potential low or high side was too elevated, I could not be aggressive with the or throttle.

Note much balling up of tire rubber on the side.

—  after 4 I came in and reduced the pressure to 38 and 35 rear. All bumps were noticeable and the roll profile of the was very solid with little sidewall flex nice. A much more feeling and throttle roll ons and braking were much pronounced and aggressive.

— three laps pressure was reduced to 36 front and 33 Sidewall flex became to recognize as did the change in roll side to side much on the transitions and less steering very hard trail Not what I was looking for therefore in a few I had gone from bad to bad.

session 2 could start, the had to cool off as much as possible in the for 40 minutes. The tires were filled with air and put on the warmers for 30 and then set at 38 front and 35 rear immediately heading out onto the The goal was to put consume a full of gas on track (45 minutes) and set a pace was reasonable for that amount of on the bike at 2:03 which be the top of A group at this track.

The roll profile of the tire was firm allowing very transitions side to side. very heavy trail the bumps were more but there was no deflection, so corner was much more precise. I not feel the side wall much on flat or off camber but at full load on up hill braking corners I could the sidewall start to change which altered the steering

As this was only experienced in 2 at this track, that was a trade in my book.

Mid corner the felt much more as did the bike with feedback through the bars rather being completely absorbed by the The added bonus was that mid corrections were much precise and happened quicker.  brought up my mid corner speed and allowed me to feel much relaxed in changing lines on working my way through traffic.

On corner exit, the sidewall firm in all but the hardest accelerating In those turns it felt more of a drift than and that was verified in turn 6 and 8 you go to full throttle quickly. So, a potential further test of one pound lower in the rear to see if returns as drifting serves no other than for fun!

All in all a much better session full confidence in the tires the front, so much so that the Pucks happily started very heavily again life grand!

Manufacturers have to put out a starting for tire pressures, so you are given information. That doesn’t into account ambient and temperature, your lap time and ability, your riding and the compound you are using. You cannot put tires on a bike any more, you to be very selective what you based on the type of use you are putting the through.

Street, track or you must take the time to appropriate geometry and suspension to accommodate the tire carcass and and there’s no short cut to that even for people like me do this every day. are very expensive when you get track/race use, so we need to get the out of them.

With a well set up and suspension, that is a balancing act grip and longevity based on


know which tires can run in direction and which cannot. DO NOT any circumstances guess. From the answer is no with the R10 – it is directional so sure when you pick wheels up the arrow is facing the way.
