I have purchased a set of MRR HR2s and I have to say, I find them quite sexy. I have also purchased a set of Eibach Prokit springs for my 2006 G35 sedan. the rim sizes are 19x8.5(F) with a 35offset and 19x9.5(r) with a 45 or 48offset, I forgot which one, but as it goes for tires size, I'm still in question. I've used a tire calculator trying to figure out how close to the wheel diameter of the stock size to keep close to. I usually see most G owners with sedans stick with 245/35/19(f) and 275/30/19(r). I've seen some sedans where the rear tire was a 35series but looking closer it still looked a little big in the rear. It seems the 30series is not as big in some of the pics of those sedan owners who opted for 35series in the rear. Please, allow me some guidance on this matter. Oh yeah, I've gone thru quite a few of the forums looking for reviews, other's experience, or just about anything knowledgable, still no solid closure to what I seek. In short, should I go with 275/35/19(r), 275/30/19(r), or 265/35/19(r)? Any advice would be appreciated.

 

go with a 35 series in the rear. Whether you do 255/265/275, it will look much better than a 30 series. I never liked my tires when i had 275/30/19's. With that +45 offset, i'd personally run a 275/35.

and if you look at overall diameter, a 245/35/19 front is a tad taller than a 275/30... doesnt make much sense running a taller tire up front on a RWD car, or any car for that matter. If you're worried about it looking too tall... run a 265/35/19

Cool, but let me ask you this, have you heard about if the diameter is to much more than the stock diameter, that it would affect the VDC or brakes some way? I like the idea of tires size you speak of, I just don't want to have issues with my VDC or abs.

 

you will NOT have any problems with your VDC or ABS if you go with any of the otpions that you or myself stated. a 275/30/20 is almost the same exact diamter as a 275/35/19 which is what i used to run and never had a problem.

There is a certain percentage factor of variability built in. I'm not sure what Nissan's specs are but usually it's around 3% on some of the other makes i am familiar with.

The sizes stated are a 2.1% difference. If you want to reduce that, you could run a 255/35/19 up front (26.0" dia) but unsure if it will clear the fender lip. It will fit the rim fine however

 

Awesome, how was your G when you lowered it on the 275/35/19s? I have some eibach prokit springs that I plan to put on as well as the alignment when all is complete. Many have said that with those springs I shouldn't have to worry about rolling my fenders, but I just wanted to know if you were familiar with them.

 

I've never had a 275/35/19, i was slammed on 275/30/20's with a 20x10 +40 wheel.



Whether or not you have to roll your rear fenders depends upon if you are going to correct the added negative camber after the drop. If you just drop the car, even out the camber side to side and set the toe, i dont think you'll need to roll the fenders.

 

listen to gdup, he's the tire professor!

 

I seen your G, and I must say "Gorgeous!", I was told about camber thing and that some neg cam isn't bad. The shop in texas said when I'm ready to do the springs then they'll see how neg to go.

 

If don't mind me asking, but what is the tire size on your G from the pic? Thanks for your info, I think I'll do the 265 in the rear like you suggested. Actually that was what I was looking at originally before.
