with 18x11 and 18x11 MPSC tires is no longer an option, what do you guys recommend for R-tire that can be used on street and track.
I know Hoosier is a great tire, but not recommended for highway use and i "think" i will get pulled over at Nurburgring.

My goal is to try and improve the Viper ACR Nurburgring time and i need the best legal rubber i can put on Dymag 18x11 and 18x13.

Hoosier A6

It is a DOT tire, if needed cut a couple more grooves in it.

Streetable DOT-R leads you down to Toyo RA-1, Toyo R888, and Nitto 555RII. They're nowhere near a Hoosier, but they're a lot better than a "summer" tire.

If you are looking for a "true" street tire that is close to a R-comp look at the kumho XS. They are what all the street class drivers are running now. If you want a R tire with some tread on it not just the two grooves, look at the kumho victoracer V700. That is what I have been autocrossing my '73 on for years since they are cheaper than the V710s (although I saw tire rack has them about the same price now!). I have never tried the toyos or nittos since they only make a 245 wide tire in 16" size. I run 265 or 275 on a 9.5" rim.

The best R compund for outright grip is the hoosier A6. They are DOT legal and are leagal to drive on the street (at least in the USA, i dont' know about Germany).

V700 only comes in 16" or 17", C6Z will want 18" or 18"/19" combo...

vettehardt

I only use the 16" so I didn't know that the victoracer V700 only went to 17". I quickly looked at Tire Rack and saw the ecsta V700s and they do make them in a 18" up to a 335/35. They still have more tread grooves than the v710s, but my dad tried a set once on his 90 zr-1 and they wore out faster and wern't as sticky as the victoracer 700s.

I concur!

Rune,

I know they are not used or discussed a lot by members of this Forum, but you may consider the Pirelli PZero Corsa R compound tires.

They make a 295/30R18 tire that is 24.73 inches tall that would work on your 18 x 11 front rims.

They also make a 335/30R18 tire that is 25.91 inches tall that would work on your 18 x 13 rear rims.

Good luck with your decision.

what tires can you get in Norway ?

Pumba

Careful!

Hoosier states in their literature that they should not be driven on the street.

Z06Norway

Almost none, but i import them as needed

Pumba i agree, A6 or R6 which i would use on Nurburgring as the A6 would burn up too fast, they are both not suited for street driving.
But GREAT R-Tire.

Pireli P-Zero could be an option.

I cant understand why Michelin quit making 345/30/18

Rune

AU N EGL

In that case the Hoosier GT tires

Pirrelli P-Zero is a run flat IIRC not what you want either

vettehardt

The only state that because of the tread (lack of) and how easy it is to puncture a tire. If you were driving on the street and hit a puddle, the tires will not grip and there is a chance to wreck. Even a small rock can puncture one of these tires and there is a chance for a wreck. But there are those same dangers on a race track, just not as much traffic to run into. If you are smart you can drive these tires on the street. I haven't done it often, but have driven about 35 miles away to an autocross and back home on a set of hoosiers (back when the S03s were new!).

rustyguns

dude they have steel belts, that is why they are DOT rated, a small rock won't kill it. they are not weak, My god we hit thousands of small rocks on our tracks !, but wet grip is horrid on most

lawyers make them right that crapola
