Just note that my new tires (p zero) at the rear rub slightly with the fender

Will check if the screw of the fender loosen
i suppose there is no such issue when using toyo by the previous owner

some of you are even talking about 3xx at the rear. You change the shape of inner fender? Spacer is not a good idea according to some article on car mods

295 what? My 19 inch 295 are great. What drop do you have?

My 315's don't rub.
What offset and width are your rears?

i can't remember all the rub from 19's since i ditched them as an early learning experiment, but rolling your rear fenders should eliminate that rub.

thanks for the advice
btw what is the meaning of "rolling"
😆

fung0001

Yes
it may due to the off set of my 19" wheels
but i also learn that different tires have different thickness / stiffness of its wall & therefore some may cause rubbing and some not although both are 295 19"

P Zeros are fat, and wider than the PS2's and other brands despite being the same numbers. I know this because I've had PS2's on my M5 and than switched to P Zero, was a huge difference.

sorry, many have had to roll their rear fenders to obtain more clearance than the original fenders allow. it's done gently with a mallet/hammer lol. but it helps. i'm not sure it'll help you, since i couldnt see where the rub is in the pic. this ( iirc? ) will only help rubbing at the outside edges, less so the inside. most porsche techs know how to properly do this.

mine on 19's rubbed at hard lock L/R and also on major compression in bouncing tight canyon cornering.

EDIT: Its only just occurred to me ( coffee! ) that rolling the rears is generally prescribed to gain more clearance in width! to accommodate a wider rear tire ( 315/30 vs 295 etc..) but your issue seems to stem from having a taller wheel, so i'm not at all sure that rolling would even help!

have you checked your suspension for sagging? that could also contribute to this issue if on original or *old* springs ( if oem ).

295/?? - 19.

just saw this..

spacers are fine on 18's. it's common to roll fenders ( yes change the shape ) and run a 7X15mm spacers for a wider/f;latter stance ( looks great too! ) and the slightly wider 315/30/18 tire. all of this is rendered moot by your running 19's! so... sorry!

In your case you can solve the issue with bending the fender liner bracket back a bit or install the GT2 version which pull the liner closer to the boost hose.

Offset, wheel widths, tire height, tire width, fender liner brackets, fender roll.....all play a part in how much tire you can fit without rubbing. Wheel diameter does not make any difference, the over all tire diameter does. With careful selection you can stuff a lot of tire back there. I'm running tall 26.0" tires (335/30/18) on 13" wide wheels with no rubbing.

Same question?
I'm on 295/30-19, no issues. Looks like you are slightly rubbing on the inside plastic liner? If so spacers might solve it.

Along with the full tire size, please let us know your wheel width and offset.

I know it's not the issue here, but I run a 315/30/18 with about 2mm to spare. No rubbing at all.

Without rolled fenders? That's GT2 size but they have rolled fenders.

Nothing ever touched. Regular TT liners too. Car is lowered as well. Fitment is the key! 18x12 and 315/30/18
