I only drive my 911 on nice days and if it rains I just slow down with r compounds. I just expect to buy a new set every year. I know many hobbies that cost much more.

Perhaps in Europe you can still get tires for these size rims, but you ought to check again just to be sure. Here in the US, the choice in 16" rubber in our sizes is now down to just 2 choices on tire-rack.com (one street and one track-only compound.)
Many 930 owners with the 7 & 9 16" are going to 17s and 18s just for tires.

I'm also in agreement that using R tires all of the time is not out of the question.

However, it's pretty cold most of the time in Sweden, isn't it? You may find that the R tires will be very slippery when cold and you may have very poor performance most of the time on the road in cold weather. Depending on your ratio of street miles to track miles, you may want to rethink how aggressive a tire you want . A very high performance street tire may give you much better cold weather grip while still providing acceptable grip at the track. The Dunlop Direzza may be good here.

Good Luck!

Vntgspd brings up a good point - Really why the R-comps? With some of the new street tires out there (I have the Nitto 05) many with the Dunlops or new bridgestones that are a better street tire and only a small notch below R-comps. Unless you are looking for that extra 5 seconds a lap - (and really what's the point in a DE) why? Good point on the cold - the R-comps need heat to stick - not much heat in Sweden, right?

I already stated that I run my 911 exclusively on r compounds. My father has a 993 that is transformed by r compounds. The ride is squishy and soft with street tires and with the r comps the car is transpormed to a tight grippy beast!

Hello,
Thought I would add my $0.02. I was running Falken Azenis 205/50/15 on cookies, thought I would change it up with the Fuchs 7"X16"s, and installed Toyo TR-1s 205/55/16s. The Toyos are good enough to run for awhile(winter), but I will be going back to something more like the Falkens, them suckers were like velcro, I wore the original Michelin Pilots that came on the car with most of their tread completely bald in 7K miles. Seems sliding in and out of corners will do that to hockey pucks. In normal 50% driving the Toyos are fine, but the Falkens velcro like grip is sorely missed, I drove the Falkens for 4K miles like they were stolen and they still look great, tread wise.

Mid spring to mid fall is ok in southern Sweden, but the rest of the year it is mainly between -5C to +10C. So the temperature is deifinitively a factor! I drive the car down to ca 5C, or low 40's F, after that they start salting the roads. Temperature would probably be my only reason to opt for other alternatives, however, I am very curious on the performance of R-tires.

I ran 3 seasons on Yokohamas A048 and the last 2 seasons on Toyos R888 on street here in Switzerland. Temps have been between 10 to over 30°C. Both work very well on Street. I know, I cannot reach temperatures like on track, but their grip level is still far over street tires. Toyos feel a bit better cold. But even the Yokos are cold that good, that I had never a bad feeling or lack of grip. Wet conditions are not the strength of them, but it last to go with traffic without fear.

So if you just want to go for a ride on a nice sunny day, even in autumn, I would always prefer them over street tires.

I ordered a set of R888s. Can't wait to try them out!
