Tyre recommendation for Tuscan please

[JK TVR]

I have a Tuscan S with an upgraded 4.3 speed six. I've owned the car for many years and have always run it on Toyos, initially T1S or T1R. When I upgraded to the 4.3 I couldn't use the additional power with these tyres (wheel spin all the way to 80 mph). I was then recommended the Toyo R1R which is brilliant in the dry but completely useless in the wet, which is fine for most of my driving, however I'm going on a serious road trip to the Alps and need something that can perform as well as the R1R in the dry but also perform relatively well in the wet, in case it rains heavily? Does such a tyre exist? Any help much appreciated.

Thanks for that
