I got some toyos sittin in my garage in 245's on the fronts...Any problems running these...

I am runnin a 315/25/19 rear...and have adj coilovers...

Let me know your thoughts guys...

 

actually
thats the tire size i will be running on the front of mine
however, im RWD..

i think if u do a 315 25 and 245 35 , you might upset the diffs

 

no I checked with my porsche mechanic, whos actually good at what he does...he said rubbing issues will be it...do you know how much it will rub?

 

If you are awd do not do it as it can cause your front differential to fail. You should only run a 235/35/19 if you are awd.

 

have there been any failures due to this?

 

I've read postings on front diff failures, but I believe the diameter difference was larger than what you're looking at (25.8 F, 25.2R).

 

Thats exactly what I meant, danyol...I cant see diff failure for .06mm difference. I could understand if it was like 1" or more or even mismatched tires and sidewalls...

But does anyone know how much rubbin? and if there are proven facts around diff breaking with this setup

 

i had that size as a front tire.. no rubbing issues... it worked fine on my car... just need to match them up with a close rear tire size

 

I think the issue is more to do with PSM activation, Boca doesn't have an issue that's a good sign.
Boca, no premature activation of the PSM on bumps or fast exit ramps (I sometimes see it on the I-95 Copans exit from the S.bound side)?

 

I called damon at tire rack that said, it would have NO impact Whatsoever on diff but might cause rubbin so play with supsension to adjust height

 

My TT is max lowered with PSS9s & Cargraphic 19's and I have 245/35/19's fronts, no rubbing issues but it is very very tight but looks fab as well as a consequence

 

I have that size on the front with 295-30-19 in the rear and I get minimal rubbing in the front, and ONLY when I have the wheel at full lock. I just make sure i don't go full lock and I don't rub. The car is lowered pretty low as well. The rears are another matter though...

 

25 series in the rear will cure that - I had the same issue

 

GT650
why dont you go with a 255/30/19
on my 19" i-forged, the 235 BARELY rubs ducting for the radiators...


depending on how aggressive your drop, and what kind of wheels (offset) you have, it might rub

i had a 245 michelin ps2 on my car, and it did rub, but i dont care because im gonna have the suspension re-done so it doesnt rub ..

 

I didnt have any psm issues when I had the tires on my car.. and my car has lowered springs also
