Toyo R1 feels very wabbley

[vegasviper]

I have 44psi and the Toyo feels very wabbley compared to Pilot Sports. Is this normal of Toyo, do i need more air than 44psi?

I am not familiar with the R1, but I am assuming 44psi is the max pressure they are rated at on the sidewall? You should probably be running considerably less, like around 29-32 or so.

why are the not as responsive as Pilot Sports?

The toyo R1? The R compounds used in many many car racing series? I run them on the race track, not on a viper though. I didn't notice any "wobbliness" in them??!?! Not sure what you are experiencing. 44 psi is wayyy too high. After running hot (like after a lapping session) they should not be over 41 psi. Try putting them down to like 34 psi.

seems like there is much more body roll. Also, very sensitive to sreering wheel. At high speed it feel loose like if car is moving side to side. At first thought it needs more air but it feels the same by adding more air
