The Yokohama S.drive steps up to the plate.

Wednesday, July 7, 2010 by Clint Crabtree
Yokohama S.driveOur current test of Ultra High Performance tires proved the Yokohama S.drive is a very capable tire. The tire was tested against the BFGoodrich g-Force Sport, Firestone Firehawk Wide Oval and the Kumho Ecsta SPT KU31. These tires were evaluated during a Real World Road Ride and during drives in wet and dry conditions on our test track.

After putting the tires through their paces, I found that the Yokohama S.drive had  crisp steering response with excellent dry and wet traction. The S.Drive can run with the best.

A full test report will be online soon.

I am concerned about the huge inconsistency between s.drive's tested wet performance on May 9, 2008 compared to June 11, 2010. It basically went from worst to best in the wet. Why?

If you look at rank order of the S.drive’s wet performance versus the competitors, the difference lies in the competitive set, which is different between these two tests. In the 2008 test, the comparison tires proved to offer better wet grip than the Yokohama tire. In the 2010 test, the Yokohama proved to work better than most of the others. 2008 test: BFGoodrich g-Force KDW2 Bridgestone Potenza RE760 Sport Michelin Pilot Exalto PE2 Yokohama S.drive 2010 test: BFGoodrich g-Force Sport Firestone Wide Oval Indy 500 Kumho Ecsta SPT Yokohama S.drive Recognizing that over the two year span between the tests there are differences in the test vehicles used (2008 E90 Coupe vs. 2011 E92 Coupe), ambient conditions and the condition of the track surface, the basic performance of the Yokohama S.drive didn’t change that much: Total Lap Time (wet) 2008 31.46 seconds 2010 31.63 seconds 50-0 ABS Stop (wet) 2008 98.4’ 2010 104.6’ Lateral g’s (wet) 2008 0.860 g 2010 0.802 g

I have the 225/50 S drive on my 2006 Toyota Convertible. I don't think the tires have very good traction on wet roads. The car slips very easily when the pavement is wet.
