My question would if its posible to put 275 on the back without rubbing and if i put 255 in the front would they be rubbing also? , What is the cool perfect tire size for a g35 it has its normal height and i dont know the width of the rim i saw online sporza may be only 8x5. ill try to put a pic of it i saw online. also i think of putting spacers so far there is only one kind at o reilly and autozone they even told me i can put them my self? what is the common or perfect spacer size for the car sand what are the best spacers well that california has because thats where im from.here is the pic of my rims it looks exactly the same except you cant tell they are 20 "s need help please .

you can run up to a 275 up front and 305 in the back with fender roll...offset depending. as far as spacers go you can use the autozone ones but you need to measure the distance between tires and fenders and buy the appropriate thickness. the autozone ones are 7mm thick i think

 

I heard of people rubbing with 275 I'm gonna stay with 255 f and 275 rear if it doesn't rub that is, on 20 each wheels thanx

 

I have 295 on the rear with a fender roll. no rubbing. More camber can help keep you from rubbing too. I'm at -1.3 rear camber. But I have the need for more tire width.

 

Thanx not familiar with rolling fender never done it. With 255 and rear 275 its a most for fender rolling?

 

I'd say yes, but again it will depend on your camber and the offset of your wheels or how many spacers you have.

These links should help you get a few visuals.

Everything depends on the wheels width and offset. If you are considering spacers then it's pretty safe to say that the 275 will fit fine in the rear.
Is this a coupe or sedan?
As far as tires go, your best bet is to leave the 245/35 in the front and buy some 275/30/20 (285/30/20 would match the front almost exactly).
As far as spacers go, check out the vendors on here they sell some quality spacers. Don't waste your time or money on those cheap spacers from the parts store. The largest you can go while using stock studs is about 5mm and they are not hub centric.
You will want hub centric spacers(66.1mm) to prevent vibrations at higher speeds.

Look into Ichiba spacers, or hop on Ebay and look up "optionselct" they sell hub centric spacers as well.

 

IT'S coupe. I have to measure the tire and the fender to know the measure of.the spacer for.that size that I want

 

Hey man, i finally got rid of the 22s on my 04 coupe. I bought it like that so don't judge me lol. Although it was cool cuz i was the only one riding a G like that in my area, but im ready to go fast without worry now. Well i got some 20s now maya Stm's 20x8.5 front with 245/35/20 & 20x10 back with 275/30/20 all Nitto NT 555 tires. My suspension is stock and i want to accomplish the wider look in the rear which i believe a spacer will achieve. So i would like to know what size spacer i would need? Plz help as you seem wise :-)
