I had a post a few weeks ago but didnt get too many hits. Lowered on road magnet with linea dynas. I now have more vibrations with these wheels then when i was on stock n lowered. why is this so.... Is it because i have less rubber to asorb the virbration.... Anyone else experiencing this?

 

Rizzy, I work for a Toyota dealer out in NJ and we are constantly being sent to monthly courses involving detailed explanations of various Toyota/Lexus/Scion models as well as the competition. In a few of these courses we had discussed various types of 4WD and AWD systems Toyota uses, from viscous couplings to on-the-fly to full time AWD systems, mechanics and intricate workings. In one of these courses we also specifically discussed locking center differentials and why they can only be used in **** weather driving straight forward or back only at slow speeds due to a nasty effect known as "drivetrain binding". This is when u lock a center differential and attempt to turn a car on dry pavement, since all four wheels are locked together, they cannot spin at different speeds during a turn and will cause the the wheels to hop and ur differential to jam up....hence my understanding of wheels turning at different speeds during cornering and turns....as far as most if not all passenger sedans have either a viscous coupling or full time awd with no locking center differntial, this wouldnt be an issue for us...a regular differnential is used to allow for this differnce in wheel spin from sided to side ( or front to back in the case of a center differential)....so yea, this is my educated approach to my argument

 

can someone tell me what tire sizes I should use with this set up

19x8.5 + 25 / 19x9.5 +40

 

^235/35/19 and 275/30/19 will be just fine.

 

Can someone tell me what tire sizes I should use with this set up for IS250 AWD. tks.

19X9 +35
19X10 +40

 

I HAVE A 08 IS250 AWD i want the biggest 20 inch staggered set up possible without fender rolling can some one help me... can i run 245/30/20 and 285/25/20 with and rubbing or fender rolling..

 

This is my first post so go easy on me

Can someone please answer these questions for me?

Stock:
Tires - 225/45/R17
Wheels - 17/7/+50mm (I think this is right, please confirm)

Max Sizes without mods, lowering, rolling, cutting, etc...:
Tires - ???/??/??
Wheels - ??/??/+?? or ??/??/-??

Please fill in the "??" so that I can determine the biggest wheels/tires without rubbing. For those thinking that I'm lazy; I'm not, I've been researching and keept finding different answers so just want a definitive answer from experienced users.

Thanks in advance!

 

buddy, there is an infinite amount of answers to your ?????. you have to factor in wheel size, offset, tire size, and how lowered it is. it's not just black and white.

I believe stock is 17x8 +45

 

for everyone who has a 235/30/20 in front, did u need to cut any plastic to avoid rubbing? Roads are rough around here, and i wanted to go to a 235/35/20 front. Tryin to gauge if it will fit or not. Sounds like no1 has even tried it yet

 

Daxx depending on the width and offset. But 235-35-20 wont work with the awd way off. 225-30-20 work for the diameter.

 

got some good ideas from this thread.

 

Just curious, what's the biggest difference in diameter some people have been running without issues? I know the AWD is not 50/50 so some discrepancy is acceptable. One member on here and myself included will be running 215/35/19 and 235/35/19... which is a difference of ~2% in overall diameter. Has anyone else done something to this extend?

 

Still need help. I'm going to run 235/35/19 in the front just need some ideas for the rear tires. My fenders are rolled & i want to run spacers up front & on the rear. Also need help with this to, need to get this done for a car show next weekend. thanks.

 

You must run 235/35/19? If not I would so do 225/35/19 and 265/30/19. 235/35/19 goes with 275/30/19.

 

Good info. I was never doubting your posts...I was just trying to get supporting info for your statements. That's it, so don't feel offended or anything.

H-I-M - I'm +3 on offsets compared to yours (both front and rear) and I'm running 235/35/19 and 275/30/19. It's the closest rolling diameter you can get.
