G35 Sedan Tire Question (WhiteyClay this ones for you!)

[Tampa G35 Sedan 6MT]

Ok a few of us sedan owners have the coupe 19's on our sedans....

The 245 40 19 is what we have on the rear! Im looking for a wider tire for the rear of my car but i don't want any rubbing or rolling of fenders!

I found the sizes that general makes for its tires. (the ones that i want to buy)

245 35 19 (front) ($135 each)

255 35 19 ($178 each)265 30 19 ($147 each)275 30 19 ($160 each)

What is the best size for the rear...I know that i could put a 255 on with out a problem but what about a 265 or 275?

I really want to go with the 275 but not sure if it will work!

getting antsy???

Well, I have 245 , 35 , 20 on mine, no rubbing whatsoever, but I don't know about the 275s... not going to happen,

I'd suggest keep the 245s, but install a 8-10mm spacer for the rears, I'm thinking about it, well, toying with it slightly, I noticed a big difference in the stance when I went to the 20s x 8.5... so I may not bother.

Good luck

I have already answered this. 265=NO, 275=HELL NO, 255/35=MAYBE if you roll the fenders. To run a 275 tire, I recommend a 9-9.5" wheel with about a 38-40 offset to fit without any modifications and flush with the fender.

http://www.1010tires.com and use the tire size calculator. Enter the OEM specs, then enter in additional tire sizes you would like to use. If the difference in diameter is more than 3% if will tell you and its not recommended. But in you case the offset of the wheel limits you to what size tire you can run. The coupe wheels on a sedan are more aggressive offsets than they are on the coupes. Guys with the coupes can run a 10-10.5 wheel with 20 offset and no rubbing issues. Sedan weren't designed to run aggressive offsets. You can run a wide tire and wheel, but the offset will not be aggressive. Most guys that run a 275 tire are using 9.5-10" wheels with 42-45 offset. The offset on your coupe wheels are 30 front and 33 rear. Like I have said before, if you had the correct offset to run a 275 tire, it is pointless on a 8.5" wheel.

The 255/40/19 works fine. Your speedo is off by about 1mph/100mph

The 275/30 will be too short by .3" in radius. HOWEVER, the coupe and sedan overall diameters are different IIRC.

Tire rack suggests a 255/35/19. I think RED_DET said the 275s weren't going to fit on the sedans without modifications.

[RED_DET]

Exactly and the 265/30= Speedometer Difference: 4.239% too fast (Diameter Difference: 4.07%) no way

The 245/35= Speedometer Difference: 2.214% too fast (Diameter Difference: 2.17%) alright, better size available.

275/30= Speedometer Difference: 3.264% too fast (Diameter Difference: 3.16%) no way

I don't knwow if this help you, but if your 19s are 8.0 in front and 8.5 at the rear then, 245 - 35 - 19 will work in the front and 275 - 35 - 19 will work at the rear. I have 19 inch wheels and it looks great. Not a single problem with VDC or suspension with the new tire sizes.

[Tampa G35 Sedan 6MT]

I don't care about the speedo... Will the 265 30 19 rub the fender?

That is only 1CM difference on each side of the wheel from the 245 40.

I know it will be shorter but i don't see how 1cm could make that much of a difference?

ABS and VDC rely on those tire heights to be correct.

If you deviate too far from front to back, you may run into some serious issues.

[RED_DET]

I already said no the size wont work.

[RED_DET]

What are the offset of your wheels?

[RED_DET]

AMEN.

[Tampa G35 Sedan 6MT]

looks like I will be ordering 255 35 19 (rear) and 245 35 19 (front)

Thanks for all your help guys!

I better see pics after you get the 255/35's on. I plan on trying a 255/40 on the z track wheels and want to get an idea of how they will look.

[WhiteyClay]

I heard people saying that they have 275 but they had to bend in their quarterpanel under the tire cuz it will definetly RUB.....so If I were you Ill stick to 265 or 255.I was doing a research about it and this is what I found out so far

here is a tire calculator see if its helpfull

Sorry I couldnt reply faster cuz I was stuck putting my test pipes.People say its 20 min job. and I say BULL... with out the car being lifted it took me almost 2 hours, and thats mostly taking Cats out. putting pipes in was easy..

You might be right but remember that us sedans owners upgraded our wheels from 17" already so our Speedo is already off. Be4 on my stock wheels 17" (I forgot the tire size) I couldnt do a big burnout. Now with my 19" I launch the car from 3.5-5 RPMs My G35 burns like a 5.0 mustang

[Beancooker]

If you originally had a 245/50/17 and replaced it with a 245/40/19, your spedometer will only be off .03%

That is a difference of 60mph stock, and 60.2mph on the 19's.

So unless you just aimlessly slapped whatever tires on the 19's, your spedometer shouldn't be off at all.

I have 275/40/18s.. but it's a coupe..

Coupe > Sedan

[RED_DET]

of course, big fat heavy coupe over a sedan, what were we thinking.
