Looks good! I have the 305s mounted to my 12" wheels right now and they were stretched too much for my liking. I would be thinking about it during hard corners.

What size wheel are you running?

 

The first picture is the 305/645/18 on the 12" wheels and you can see how far they had to stretch.

The last two pictures are the 325/660/18 and they fit much better.

 

Thought 325/660-18 will fit 13J, not so sure anymore, anybody has closer pics in 13J ?

 

Here you go - they don't fit even though it doesn't look to bad in the pics it was really stretched
And the comparison is from John its a 335 NT-01 vs the 325 Pirelli the only 325 pirelli that fits on the 13" is the rain tire.

 

thanks, nt01 looking good, but pirelli could have been wider..

 

The pirellis run skinny, Yokos are wider. A Yoko A005 slick in a 320/650-18 would be great with a 13 as Yoko lists a recommended 12-14" rim. Pair that with a front A005 250/640-18 on a 9.5 or 10" rim.

 

To be honest as I can run a 660 tall tire in front, might look for 660/660 or 660/680 combo F/R, just to have some more rubber improves grip as far as I know

 

Guys anybody tried AVON slicks?

I am looking over

270-650-18 front, real size 25.8", rim 10-11", 302mm wide and 272mm tread
335-645-18 rears, real size 25.75", rim 12.5-13.5", 338mm wide and 330 tread

they come in HARD or MEDIUM compound, I would go for HARD front and rears.
The AVONS are maybe first choice in Europe regarding HillClimb events btw

Other than that I dont know if should go Pirelli, the rear tire seems really narrow for my 10"f/13"r combo

What do you think?

 

According to several sources, 680 won't fit. Might want to see if anyone has done it on a turbo.

 

680s work, the problem is the fronts dont accept more than 645-650 using oem fenders. The gap btw front and rears 645-680 is too much for abs, psm etc even for rwd config. Even with psm totally off the abs doesnt like the combo.

One work around is to use 660s in the front instead of 645s so the gap will be acceptable/tolerable for abs ..

 

John are the yokos fast enough? Heard they arent that good compared to orher slicks

 

Hmmmmm 27-65/18 and 30-65/18 michelins might work too on 10/13 combo ?

 

No no, don't use the Michelins then everything else will completely suck
