Yoko AO32Rs fairly noisy on the track. Predictable at the limit, wear well. Lots of rubber to start. Good rain tire for beginning of season then dry as they break in and wear.
Used them on my 914-6 2.7RS and a 944 Turbo with 300HP. Probably the compromise tire of the 3. Yokos tend to like lots of negative camber! Expensive in comparison to other choices.
No personal experience with the others,
But I can tell you that Jeff Reitmeir has been using the Toyos on his 924S Cp car all seaon along with co-driver jim Lane. They seem to like the tire and it wears well.
Lots of timetrialers have been using them this year...so it either is working well or eveyone is following a few leaders.
Victoracers are probably the stickiest of the 3, but seem to wear well..especially on a lightweight car such as a 914.
The Kumhos will be my choice for next season of TT and AX.
Would consider the Toyos if I could find someone in the San Jose area that carries them and won't gouge me on the price.
