It all depends on a lot of things.
I also agree on big dogs coment.
trying to find a decent tyre which does both well is pretty hard. Also the problem you have is that a lot of the tyres which are avail in the 15\" or 17\" series are not avail in 205/45x16 unfortunately the sexy OEM 16\" wheels for the NB's or any 16\" wheel for that matter are ignored by a lot of manufactures when it comes to serious road tyres.
you need to figure out how often you intend to track your car.
Then you need to figure out How many k's you are going to do.
you need to figure out where & how you will be driving your car.
C drives, T1-R's, GIII & so on are all mediocre tires as far as i'm concerned. For me they are a ordenary tyre.
But thats only because they don't suit my application.once you get into R Compound the compromises become quite.......obvious. I personally wouldn't drive an R compound on the street. Let alone in the cold weather conditions we are having right now in Sydney. They wouldn't be better than a C drive but you would also start killing the tyre
any tyres can last for abt 30,000 km, I would think that they last extremely long~~~
.so we can assume that if a tyre lasts you 8-15 k K'm you would be happy.
If you do decide you want 1 set of tyres for all purpose
I suggest you look at the federal
RS595. Its comparable to the Azenis RT615 but avail in 16\". But just over the $280 mark.
also check out the R888. its an R compound & slotted somewhere between the Azenis RT615 & DO1's probably
The Federal RS 595 is very similar to the Azenis RT615 as its a road compound very stiff sidewalls byt has a semislick trad pattern.
Azenis RT615 not aplicable.....doesnt't come in the 16\" size you require
hannoock.....cant recall the name No. the tyre not quite as good as the RT615 but also not as expensive.
also those tyres mentioned in CT's thread might be worth having a closer look.
R888.....well from what i've heard....awsome tyre......doesn't seem to suffer from heat cycles as much as the DO1's but i'm sure they do suffer a little.....just not as bad as DO1's.
Now these Tyres I've just mentioned are not the best thing ever...... They are the type of tyre which suits my own driving & the sort of driving I do. These tires also have compromises. which you need to understand......& by what you said.....seems as though you do.
having said that. My car is a weekend warrior. sees the track maybe one or twice a year. But sees a fair bit of Putty Rd & old pacific Hwy. I can also assure you i slow down in the rain. This year I'll get 7k km at the most. so its not a real lot.
but if you are planning on going to every club meet at wakefield for the next 12 mths & do your fair share of road driving. DO1 FTW on 15\". For the road I heard the Michelins are good too. Not just from CB.
so unfortunaltey......no easy answer.Just like bigdog said.....
