Basic IS wheel size guide

Recommended Posts

Here are some basic wheel tyre combinations that can fit, if you have any more post them below.

PCD = 114.3mm Offset = 50mm

Standard Rim f/r = 17"x7"

Standard Tyre f/r = 215/45-17

(A -40mm drop is possible with this combination)

18" upgrade f/r =18"x7 1/2"

18" upgrade f/r =225/40/18

18" upgrade f/r =18"x8"

18" upgrade f/r =225/40/18

18" upgrade r =18"x8.5"

18" upgrade r =255/35-18

(A -30mm drop is possible with these combinations, however minor arch rolling is needed with the 255/35 combination)

19" upgrade f/r =19"x8"

19" upgrade f/r = 235/35-19

(A -25mm drop is possible with these combinations)

With 19's don't run any rim bigger than 8" on the front as it will hit the strut.19's will rub on the front inner arch at full lock, but this can be solved by cutting or bending away some of the plastic trim.

:rolleyes: Of course for the nutter out there even a -60mm drop is possible with 19's.....................you know who you are!!!!:P

Always remember anyone can fit big wheels and park up at a show, just remember living with them every day is a whole lot more work!:D

With anything bigger than 19's I would sugest an arch extension kit. This would bring them away from the inner arch to provide clearence.

OFFSETS

FRONT

width | offset | tires range (width)

7 = 40 and up 215-225

7.5 = 42 and up 215-235

8 = 43 and up 215-235

8.5 = 45 and up 215-225

REAR

7 = 40 and up 215-225

7.5 = 40 and up 215-235

8 = 42 and up 215-245

8.5 = 45 and up 225-265 (255-265 requires rolling or having lip)

9 = 49 and up 235-275 (MAY require rolling or shaving lip)

9.5 = 52 and up 245-285 (MAY require rolling or shaving lip, 285 may require more modification)

10 = 45 and up 255-315(requires pulling fender)

i'm guessing these et's are based on a minimum so they dont foul the struts, anyone have any idea what the maximum et you can so they dont stick out past the wheel arches?

As you can see from above, it depends on what wheel size your after :whistling:

Wow, this is all greek to me.

I'm looking at getting a set of 17" or 18" alloy wheels for an IS250 and by the looks of this I will have to get them professionally fitted as I have no bloomin' idea what the above posts mean! :)

Interestingly, not many websites offer wheels for the IS250. Plenty offer them for the IS200 but I am unsure if the dimensions of the wheels, arches and so on will be the same, so I am reluctant to buy any.

I've trawled this forum looking for any posts that might help me but I either draw a blank or I find posts with information that makes no sense to me, a complete idiot when it comes to wheels.

I would be ever so grateful if someone could let me know if these wheels will fit and what size tyres I should be getting please?

Many thanks

What do you mean wrong amount of studs? Is it different than the pic then as the IS250 is a five stud. You're right about the width, the standard OEM's after 2006 have 8" wide fronts and 8.5" rears..the very first cars had 8" all round but still had wider tyres on the rear.

Don't know how many times I have to put this up...but all info is here http://www.clublexus.com/forums/showthread.php?t=201509

Yes, and just to make it clear it also says 'red.gif Fitment incorrect for your car!' Although it refers to the IS200, fitting is the same.

Here are some basic wheel tyre combinations that can fit, if you have any more post them below.

PCD = 114.3mm Offset = 45mm

Standard Rim f/r = 17"x7"

Standard Tyre f/r = 215/45-17

(A -40mm drop is possible with this combination)

18" upgrade f/r =18"x7 1/2"

18" upgrade f/r =225/40/18

18" upgrade f/r =18"x8"

18" upgrade f/r =225/40/18

18" upgrade r =18"x8.5"

18" upgrade r =255/35-18

(A -30mm drop is possible with these combinations, however minor arch rolling is needed with the 255/35 combination)

19" upgrade f/r =19"x8"

19" upgrade f/r = 235/35-19

(A -25mm drop is possible with these combinations)

With 19's don't run any rim bigger than 8" on the front as it will hit the strut.19's will rub on the front inner arch at full lock, but this can be solved by cutting or bending away some of the plastic trim.

i think the offset on the OEM 17 x 7.0 is +50

Just fitted some 18" wheels to my Altezza (ie IS200) and thought I would share the results.

Wheels 18", PCD = 114.3mm, Offset = 30mm

Tyres f/r =225/40/18

The results - quite a bit of scraping at the rear from the tyre against the inside of the guard lip at the top. The front tyre scrapes against the vented guard inner in front of the tyre too.

What next? Not too sure... Pic to follow :)

i think for a 18" the offsets should be between 40~45

i have the Is200 wheels on my swift

i have seen the above but just to ask, would 205/40/17 tyres go onto them or not? Or would it have to be 215/40/17 tyres?

i have 245/35/19 at the front and 265/30/19 at the back. Could i change back tyres for 275/35/19 without rubing the arches?

this section is for the is200

as i asked before, whats the offset

there is no need to make multiple posts asking the same thing
