19' rays on AWD?
 

okay, everyone seems to know me now.
(maybe 4drmadness/greatness will be the first to reply, like always... lol)
i guess...
lol...

i tried every rims in the world! close enough...
and nothing looks right on the sedan!
i have an Obsidian Black 04 G35x, my little brother on the other hand have the 06 IP coupe. well, my fiance was changing both our brakes, and i grabbed my little brothers rims and put them on mines! GOD DAMN IT, IT LOOKS GOOD!
i wanted the same exact wheels on mines, but i think they're staggered, because 19x8 front and 19x8.5 rear, how the hell will this work with the awd?

or should i just get all 19x8.5 all around?

or will anyone please get me all four or find someone who has all four the same sizes?!!!?!

If the overall tire diameters are within 5% or so, it should be compatible with your AWD. Or you could try to trade someone the fronts or backs so you would have all 8" or all 8.5" wheels.

Easy, just buy 4 tires that all have the same overall diameter.

AWD doesn't care if the wheels are staggered. You could run 19x8 and 19x15's and it still wouldn't care provided whatever tire sizes you run are the same outside diameter so that all 4 wheels turn at the same rate.

There are plenty of tire calculators on the net to help select matching sizes. I'm sure guys with OEM 19's on their AWD's will chime in shortly with the tire sizes they run.

so im assuming u mean, 245s all around?

Not necessarily. Running diff widths and aspect ratios can give you very close overall diameters.

I run 255-35-19 and 225-40-19 on my coupe 19s with my sedan (rwd model). Although, not a requirement, I tried to stay as close to the oem 215-55-17 size as possible..

Search for the miata.net tire calculator

Or you could run one size that would fit both wheels more or less. ie.. a 245-40 or a 235-40 or something along those lines

No not exactly.

You can vary the width of the tires provided to keep the aspect ratio in check.


For example, a 245/45/17 and a 275/40/17 are the same exact overall diameter. In other words if you put two of each on a car, the front and rear would spin at exactly the same speed therefor not affecting AWD or ABS at all.

The second number is the sidewall height in %, so 45% of 245mm is 110.25mm while 40% of 275mm is 110mm. SO in other words the sidewall height is exactly the same...meaning virtually the same outside diamter.

You could put 245's all around if you dont mind slight stretch on the rear.

Play around with this and you'll get the idea

sorry, still confused.. lol
AWD SEDANS COME HERE NOW!!!

I have a 2006 DG G35x sedan with 19" coupe Rays (8" front, 8.5" rear). I wrapped each corner in 245/40R19 Yokohama s.drives. I have experienced no problems with the VDC or AWD system. Also, there is no rubbing.

The only drawback of this setup is the inability to rotate tires.

Lol okay


245/40R19 all around

/thread

oh yeah!
now im getting it!
hahahaha!

they will work fine. I sold my coupe 19's to Skyfox16 and I had 245/35/19f, 255/35/19r on them. He has an 05x and he said they bolted up just fine with no issues.

Your AWD light comes on if you go beyond 255 or something like that. So 245 in the fronts and 255 in the back and your good to go, and you get that staggered look.

Incorrect statements like this is why this is such a hard concept for a lot of people to grasp.

Plain and simple....as long as the front and rear OVERALL tire diameters are equal, it doesn't matter how wide the rims and/or tires are. They just need to spin at the same rate.


Whether or not you can fit a wheel or tire in the wheel well is a totally different story

Oh i see so 245/40/19 and 275/35/19 are basically the same thing, and it wouldn't throw off a AWD light or abs light?

Nope, because a 245/40/19 is 26.7" in diamter and a 275/35/19 is 26.6" in diameter. The difference is negligible..it's 2.5 millimeters. No different than haveing low tread in the rear. Whether or not you can fit a 275 into the fenderwell is a different story.

So both tires would be turning at the same speed. The AWD and ABS won't know it at all.

Unsure what the specs are to trip the AWD or ABS faults. With most cars, ABS is around 3% difference in rotational speed, but i don't know the specs on the G35 at all.
