Hate the 17's...Need 19's

Discussion of Infiniti's amazing (and underrated) sport-luxury crossovers, the EX35 and EX37. For 2014, the EX series will be renamed QX50, in line with Ininfiit's new naming conventions.

Hey everyone,Picked up my EX35 this week and hate the 17" rims. I didn't opt for the 18's cause they still didn't look great. Although 20's don't look bad, I am really looking for 19" rims. I know the bolt pattern I need however I am confused about the spacing, bore, etc. I know the G has 19" wheels and the M has 20's as well. Is it safe to say that any Infiniti wheel will work on the EX35 without needing to change the spacing, bore? In other words, if I bought Infiniti 19" or 20" wheels, can I just bolt them on without needing to adjust anything? Thanks

Bigger than 18 won't improve handling and will slow the car down with the additional weight. The lower profile tires and additional un-sprung weight will have a negative impact on the ride quality. You also get the HotWheels effect/look when the wheels are out of proportion with the rest of the styling lines on the vehicle.

Agree... I think 19" is the ideal size for a more sport & aggressive look. 20 is too much for my taste... The down side is that there is not many alternatives of tires for the ideal size or proportion (235/45-19). You should keep the overall diameter.

All current Infiniti models share the same bolt pattern...5 x 4.50 or 5 x 114.3

Good luck,,,,

I would only go upto 19s, since EX were designed to have 17s and 18s as an option, stock suspensions were built to carry 2 inches above its standard wheels anything above its standard size will weaken the performance of the suspensions/alignments make sure to get wheel/suspension professionals opinion before you simply add 20s on your car and mess up the suspension and do realignment on all 4 wheels, I messed up my suspension of my Maxima 3 mos of driving with 19s in it(their standard size of the wheels were 16s).

Not sure why this would be the case. Even if you increased the size of the wheels, the diameter of the wheels & tires would remain the same (since the tires would become thinner) - I make the assumption that you will get proportionately sized tires). Also, if you get larger wheels that weigh the same as your smaller wheels, it should not affect the suspension a bit. I've been running larger wheels on most of my cars without affecting the suspension a bit.

If the wheels (and tires) get bigger doesn't that throw off your speedometer/odometer too?

Tire side walls are springs, you go to a lower profile you change the spring rate, which changes your suspension.

Lets think of it this way, to keep your wheel and tire overall diameter the same, you would have to get a low profile tires, low profile tires have way less rubber giving direct shocks to our suspension, I experienced this with my old car even with smaller overall diameter(my speedo was pointing faster than i was going) EX's suspension is not built to hold bumpy low profile tires. You would need firmer suspension to cover that bumpy feeling, as we know EX with 17 wheels drives much smoother in low speeds/bumps than 18s.

The spring rate is a characteristic of the suspension (i.e. how resistant a spring is to being compressed) and not of the tires. I agree that moving to lower profile tires will make you feel the bumps on the road a bit more, but the cars suspension will remain the same.

I agree the ride will feel more bumpy with low profile tires, but I was responding to your statement about moving to larger wheels messing up the suspension to a degree where realignment was required.

Usually if you move to larger wheels, you get lower profile tires and thus keeping the diameter of the wheels + tires approximately the same. But you are right, if the diameter of wheels + tires change, it will throw off your speedometer slightly. Here's an excellent tire size calculator that will also tell you the speedo error too.

It may affect the handling and put more strain on the wheel bearings/stock suspension system and will void the suspension section warranty, unless you put back old wheels/tires before visiting Infiniti service center.

answer i got from asking local Infiniti Master Tech about installing 20inch rims on my EX.
