2. If you can afford to, buy both a semislick and a road tire. The semislick are far better than the normal road tire on a track that has very good grip.
Concerning longevity, I was really surprised of how well the Asymmetric 1 behaved. As long as you are not killing the car (mostly with heavy understeer) it should be ok.
I'd even say if you can afford semis you can afford two sets of tyres as well.
It doesn't make any sense to drive semis on street as they are both relatively
bad in the wet (at least after some heat cycles) AND expensive.
thanks a mill Rex that's very helpful! My plan is to do max 1 track day a month and have only 1 set of tyres on monzas 2 so the tyres must be able to cope on wet/cold in winter months etc. Also I do 12k miles annually so ideally this one set of tyres should be ok for 1 year of driving daily and occassional track days.
Second set of tyres is not an option now as I will be doing only 12 track days max in a year. Unless I will discover that cost of regular tires due to wear exceeds maintaining two sets of tyres with new alloys as only have 1 set...
With track days every month (which isn't few) you'd most probably both miss
the grip of semis and wear your summer tyres more than most semis. To be
honest personally I find driving on track with street tyres annoying.
Get a soft summer tyre (good on wet) and a second cheap/used set of wheels
with dedicated tyres like AD08, R1-R, V70A or PS Cup. I'd even say "Direzza",
but I promise you won't spend the money.
If you need to save more money get some cheap 17" wheels. Tyres are cheaper
and there's also the Bridgestone RE070 available in 225/45 R17 at a good price.
Sadly they don't make it in 18" or in 235/45 or 235/40 R17 .
