Last Chance to get this right the first time.

Down to 2 sets of tire options . Either Michelin Pilot Sport PS2 or Goodyear Eagle F1 GS-DS in one of 2 fitments. Based upon these 2 tires I only have 2 choices to make.

19X8.5 Offset 35 MM 1. Option 245/35/19 (spec) and or tall option 245/40/19
19X9.5 Offset 40 MM 2. Option 275/30/19 (spec) and or tall option 275/35/19

Appreciate confirmation that the tall option will work? Wheel manufacturer says the tall will have issues?

I am willing to grind the rears if I have too. Just want to know going in. Car is not lowered. Never ride 4 people.

To make this less theory, and more practice, is any one running the tall option, 245/40/19 on the front of 19/8.5 35MM
and 275/35/19 on a 19X9.5 40MM??

I just want to know for sure the issues, if any, before buying the tires. Thanks in advance for any thoughts.

From previous Post Romini Says.

"well the standard within spec sizes are 245/35/19 and 275/30/19, that's totally within spec and you are fine

with 245/40/19 and 275/35/19, you get more sidewall, more comfrtable ride, but it's out of spec and your speedo will be off. from the offset, the rear will fit no problem with the tire, the front should be very ok too, might rub a bit when you doing hard lock full turns, but that's about it coz' you are not lowering. i don't know what the shops are talking about that you will rub in the back

putting 285/30/19 or 285/35/19 in the back would be nice, but you will probably rub slightly on the outside, and you will have to shave a bit of the fender in order to fit it. that's your call now."

Thank you Romini. You seemed to be more accurate than the wheel manufacture?

From Previous Post

after 4 weeks of looking I found a wheel. 19 inch Carre SP3. GS400.

1. 19X8.5 Front offset 35 MM
2. 19X9.5 Rear offset 40 MM

Expect to get new Goodyear F1 or new Michelin SP2 tires.

All the refer guides say I can run a 275/35/19 in the rear on that size 19x9.5 wheel. The wheel and offset says "conservative. Is a 285/35/19 possible for the rear? One opinion is that I would have to run a 275/30/19 in the rear? Of coarse its all in the math and no combination of wheel size, width and offset seem to be exactly the same. One sales person claims the 275/35/19 would rub with my selected wheel and I would have to run a 275/30/19 which is down on sidewall size?

I want as much rubber between the wheel rim and the road. Currently run stock 17X8 50 and 245/45/17 on both, no problems although the front is very tight.

Want the front to be conservative and stay close to 3.75 to 4 inches of sidewall height.. Want the back as big as possible without hacking up the fenders?

I don't know how you would ever know fitments for sure unless someone has the exact wheel you want to try?

CAR is GS400 standard suspension.

i have the "fat setup" and i don't have any issues at all it's lowered w/ tein flex w/ 1.25 finger gap in the front and 1 finger gap in the rear, i have 19x8.5 w/ 40mm and 5mm spacers in the front. and 19x10 w/45mm in the rear and no rub, i think w/ 285/35 vs. 275/35 will be very close to rubbing. i hope this help

Then what you are saying is that Romini fitment guide term "Fat setup" does necessarily mean fender work has to be performed?

You are clearing with 245/40/19 (40-5=35) MM fronts and 275/35/19 45 MM rears? No fender grinding.

Of coarse my wheel is 19X9.5 40MM so the offset is 5MM less than yours.

Are you sure you did no mods at all to the front? Not even to the wheel well? I know less aggressive setups still had to mess with the well.

from my experience, if you hvae the fat setup, even with conservative offset in the front, you will still rub the top of the wheel well when you go over a big bump or dip. that's just how the geometry of the wheel suspension setup is. of course the more you lower your car the more it rubs. i am at 1/2 finger front (you can thikn of me as having fat setup for that matter) and i rub the top for sure. not anymore coz' there is already a hole, haha

So are you saying the combination of 19x8.5 35 MM 245/35/19 has no issues in the front?? While 19X8.5 35 MM 245/40/19 will rub in the front every once in a while?

The combindation of 19X9.5 40MM 275/30/19 will not rub. While the 19X9.5 40MM 275/35/19 combination will rub in the back?

Pureshot. Guy that sells the wheels says "tall" is just not worth the hassel, and is sure 275/35/19 has issues on the back with his wheel..

The only thing I am willing to do is shave the rear fenders.

well, in my opinion and experience, according to your offset and size

1) 245/35/19 should be good in the front
2) 275/30/19 should be goo in the back
3) 245/40/19 will rub a bit in the front at thet top of wheel well, depends on how low you lower and the size of dip/bump
4) depending on what brand of tires you get, with 245/40/19 you might rub the outside front fender
5) 275/35/19 will have no problem in the back

i have clearance on front and rear w/ no problem at all, no fender mods needed.

GSing430

when i reverse w/ the wheels all the way turn, there's a slight touching at the bottom of the wheel well where the lip are but when i'm driving whether i hit bumps or what, i honestly don't rub. and i left the same setting as rominl on the flex w/ couple of turns lowered. there's about 2-3mm clearance when the rear is compress all the way. i tried to check my wheel well but couldn't find any signs in the front.

Thanks all

I am going with 245/35/19 on 19X8.5 fronts and 275/35/19 on 19X9.5 rears.

Does anyone have any experience with Goodyear F1 GS-D3 verses Michelin Sport SP2 (new) They are both highly rated on Tire rack/

what?! that's a wrong setup? you either do 245/35 and 275/30, or you do 245/40 and 275/35

not 245/35 and 275/35

Interesting; not sure I understand, but here is my thoughts; All on 19X8.5 35MM Front and 19X9.5 40MM rears.

earlier you say "

1) 245/35/19 should be good in the front ......... You say Ok for the front
2) 275/30/19 should be good in the back
3) 245/40/19 will rub a bit in the front at thet top of wheel well, depends on how low you lower and the size of dip/bump
4) depending on what brand of tires you get, with 245/40/19 you might rub the outside front fender
5) 275/35/19 will have no problem in the back ........ You say Ok for the back.

How are the front, that are Ok, and the back, that are OK related? Could be I just don't see that.

245/40/19 is 26.71 inches tall, 9.64 Width side wall 3.9 inch side wall. Could rub
245/35/19 is 25.75 inches tall 9.64 Width side wall 3.37 inch side wall. Is OK
275/35/19 is 26.57 inches tall 10.82 width side wall 3.78 inch side wall. Is Ok

As the preferred rear is 275/35/19 which is 26.57 inches tall, why would I want the 245/40/19 26.71 inches tall in the front that could potentially rub?? I know it has a bigger side wall, but I don't want any rubbing up front. Its also taller than the rear which could look funny?

I am sure I am missing something, just not sure what.

ah confusion confusion. 275/35 is ok, but it's out of spec. in my point 2 i also said 275/30 is ok too. you want to match the overall diameter of the front and the back. if you are getting 245/35 in the front, the matching diameter in the back would be 275/30

pureshot,

This is the key point in rominl's post. Different sizes may work on your car but once you choose a size for the front, you really should match the rear to it (or vice versa).

pureshot

Thanks All

I think we are on the same page. As soon as the wheels arrive I will order the tires. I am loking forward to changing the look.
