Well basically, I got a STEAL on 4 hankook C51 tires 275/45/18. Since I was able to get all 4 cheaper than buying 2 normally, I snagged them in hopes that I can use them on all 4 wheels.

So I'm curious if anyone has used that aggressive of a size tire on the front of a 350z before. I have new 9.5'' wheels on the way for them, so I just need to know if they have any issues with turning... Will they scrub... Or do I need a spacer. ny help would be great

 

all depends on the offset of the wheel...yes 275 will fit with proper offset

 

That is a really tall front tire....

 

275/45/18 is too F A T !

275/35/18 front and its fine.

 

Yeah I would rather them be 35 but at $500 for 4 of them, I couldn't say no... Even if I only used them for the rear. So you think I will have an issue with it being a fatter tire? The car still sits at the stock NISMO height.

Also the wheels come in either +20 or +30. I was thinking of going with +20 unless you think I need to go with +30

 

27.8" tire will have an adverse effect on gearing....


That is 3" taller than the 285/30 I use on the front/rear.

 

I know my rear tire stock was the 265/35/19... I wasn't sure how different they will be. This is actually my first adventure into testing race tires. Usually I always stick with stock or near stock sizes

 

Even if they fit on front, I imagine you would definetely have problems with rub through turning or suspension movement.

Rears might fit but yes, gearing would be off. You can always check the change in wheel/tire size and what difference it makes in overall diameter here http://www.miata.net/garage/tirecalc.html

It is a great tool that I have used many times

 

Thanks. I appreciate the link

 

Ok so according to the chart, my new tires will be 1 inch taller than my stock, which shouldn't be an issue for the rear. But your right that the circumference will end up being 3.7 inches more. I'm hoping this won't mess me up too much....

Just my biggest worry is if I scrub fender when I turn in the front

 

They don't make a 45 series tire in that compound. It's 275/35/18, which is fine assuming your wheel width and offset is appropriate.

 

OMG.... Just go ahead and ban me... I screwed up my own size. Your correct, they are 35. I apologize for my momentary mental instability... (FAIL)

 

Will fit just fine on a 9.5 front wheel with an offset between 15 and 30

 

ok great. i think im gonna make my wheels with +30 front offset. and im considering getting +20 for rear... would there be any reason not to?

 

I run 18x9.5 +20 wheels with 275x35x18 works fine and looks good (front and rear). If going for the 'look' you might want a small spacer for the rear.. i think it's fine without.

 

sounds good to me then! thanks!

 

LOL!
That's a releif. I love the 275f/275r setup. It's what i'm currently running and it feels like the Z is much more balanced.

good luck nismo! You may want to roll the rear fenders if you havent yet.
That is if you want to run a total of +10mm offset (using spacers) at the rear. It makes the 275's sit flush.

 

I run 275/35R18 on 9.5 +25mm, and they work great. I ran 275/40R18 before, and those worked fine as well.

Next time around, I might go for 285s though.
