The initial impression of the Toyo R1R in 225-40-18" WWell, they seems massive on the rim and they are very square to look at, i meassured roughly the contactpatch of the tyre and compared it to the Goodyear performancegrip 225/45-17" i took of the car. the Goodyear was app. 190mm and the Toyo 210mm.
Initial impression is that the have tons more grip than the Bridgestone Re050a i have had on the car before in same size.
one thing that i noticed with the Bridgestones after the K04 rebuild was loads of understeer, the Toyo R1R actually induces some oversteer on same suspensionsplatform (only thing changed between the use of tyre types is a WALK kit courtesy Steve P
)
So far the grip is more than acceptable for road use, the cost being more tire noise, which i can hear but the missus doesn't when she drives.
Looking forward to trying them on the ring later on, thx for reading
