Hey guys,

2 questions(if wrong section please move)

1- currently running Hankooks on oem 18's and getting near the time to change them out, however, i have been debating going to a square set up and wondered what would be the impact to speed sensor(if any) and or best choices to do so without buying new rims etc.

Rims are oem 18's w/7.5" 225/50 front and 8.5" 245/45 on back
A- can i put a single set of tires on those rims?if so whats best size?
B- should i buy a couple of rims...either 7.5 for rears or 8.5's for front and call it a day.

2-when the time comes to change the shocks/springs, what is an aftermarket choice that is similar or superior to the infiniti oem shocks/springs AND if i wanted to lower the car(which i wouldnt mind adjusting that damned rear gap by ~.75", just to better match front etc) what would be a good suggestion.

thanks

 

You can run 245/45/18s all around, the fronts on a 7.5 are a bit pinched but not crazy. As far as changing shocks, look in to the Tein Basis Z coilovers, they are a mild drop coilover that's about $500 shipped, a Japan-sourced product and will get you to the height you want. The dampers aren't adjustable, but if you don't track your car they should be set up pretty well for spirited daily drives. If you look them up, they don't list sedan part #s, but the coupe set works for the sedan too

 

Blnewt- hey man thanks for response as reading through forum, you do know tires/ rims well so valued advice. So if I run 245/45 all around, which is way better than buying 2 new rims, but what do you mean pinched? Sorry man tires/rims were never parts that I knew much on and never had staggered set up so I'm clueless.
Will check the rein z coilovers and guessing that with 245/45 up front, will my gap increase as well, currently that sits nicely with 225/50s so if these will address that then win. Also no don't track car, it's a dd .

 

The 245/45 has a similar diameter to the 225/50, as you go wider in tread you go down in sidewall series to keep diameter close, you won't notice any difference in fender gap there. As far as a pinch mount, it's when you mount a wider tire on a narrower rim, the sidewall will bulge a bit vs. a standard or stretched mount. It will work fine, the only downside is you may get a bit of sidewall roll if you really push your G in the corners. For a 245/45/18 the recommended wheel width range is 8 to 9.5". There are quite a few around here that have run 245s all around on their staggered 18s without issue. You could also take the middle ground and run 235/45/18s all around, that's what I ran on my 07 G w/ the OEM staggered wheel upgrade.

 

Blnewt- thanks for the 101, maybe I'll try both and see what looks better on car, as I am more function >form....but man do like to minize or at least not increase more fender gap, but good to know on the 235's nice goldilock zone. Thanks again man

 

Before getting to the if/how, I'm stuck on the why?. It makes no sense to put a square set of tires on staggered rims. Still won't be able to rotate them properly.

 

It's more rubber up front either way. Why can't they be rotated in a square setup, though?

 

Why? Why not? Good question for many mods/upgrades, but for me it's basically getting more life out of tires. With this set got under 20k , previous cars had easily 35+k and only difference was stagger. Also I don't fully employ the benefits of a staggered set up so goIng with a squared set up seems like a win. Also if I have the same size rubber all around why wouldn't I be able to rotate as that is a primary reason for me switching ...

 

Wider rims up front??... That's dumb. Its not "square" if the rims don't match.

 

You'd only be able to rotate tires with a true square setup, meaning all 4 wheels and tires are the same size. Even if you put the same size tires on a staggered set of wheels, you won't be able to rotate because of the different sized wheels.

 

So simple yet^^^^^^......didn't see that one coming .....back to square one.......



Why... so ...difficult !!!!!

 

You COULD put the same size tires on all 4 wheels on a staggered set and just switch the tires themselves (unmount and remount) but that would not be cost effective and time consuming. Might as well find some wheels that are all the same size, could be a good excuse to get something aftermarket.

 

Yep , thought of that initially, but then this option seemed the most cost effective, but yes I agree, not wanting to un /remount etc at rotation times...so aftermarket maybe, but I may just look for some oem 18s 8.5 , as I don't mind the rims at all, and put that size on front corners and call it a day......^^^^^right....I'm I missing anything there......captain obvious...no sarcasm

 

Makes sense if you can get a great deal on that particular size, sometimes that's the case. That was the reason I put 235s all around on my 07 years ago, it was the only size that tirerack had on a clearance, the 225s and 245s were over twice as much

 

It took 12 comments for someone to state the obvious.

OP, you have a RWD sport sedan with staggered rims. If you put proper high-performance tires on that car, expect 10 - 15k out of your rears, 15k+ out of your fronts. It's just a fact of life, man. Suck it up.
