I run T1R's on my sprint car (as do most of the sprint racers).

I currently have Perelli Rosso's on my Aero (they are absolutely rubbish) and will be swapping to T1R's as soon as I can.

You should optimise the size as well.. the 225 is a bit tight, especially as the Toyo tyres do come up a little on the smaller size..... If they are for a S1 there is some size recommendations on the S1 buyers guide section.

The only comment I have on the Toyo T1R's is that I lean on the tyres pretty hard in corners and at the longer circuits can easily melt the surface of the tyres in a single lap.... The more track oriented tyres will offer more stability in the corners as they have a thicker side wall for lateral stability as well as offering differing compounds..

That said... they will be scary in the wet and will "go off" depending on how many heat cycles you put through them.

In general the Toyo's are a good choice I think they certainly held on well on my old TVR Cerbera GT3 spec road car. smile
