Hey guys. I dont know if this has been answered yet on this forum. But what is the max size rims you can put on an RX300 without modding anything else?

I need a size width wise and height wise. Thanks all.

Im not sure on how big u want too go but i found that my 18" by 8.5 American Racing Rims http://www.americanracing.com/browse_dale_killer.asp i have the black ones. They fit well although i put TTE lowering springs that dropped my ride 1.5" front and rear. Those rims are wrapped with Toyo 245/45/18 tires. http://www.toyo.com/docs/tires/tires...category=sport They ride perfectly and a friend of mine has 20"s on his car and says he wishes he would have gone with my size becuase he has alot of vibration.

cause im thinking of getting 19" x 9.5" rims http://petrolwheels.com/wheel_styles...eel-metrix.php
and lowering my car after that. so i dont want to mod anything besides those and wonder if there will be any problems in the future.

Can you post some photo of your RX? Pls...

You might want to be careful about the offsets. The rear struts are extremely close to the tire and members who have switched to an aftermarket wheel/tire combo have either had to switch to wheel spacers to clear the strut or had light rubbing. TunedRX300 has some SSR Competition wheels with H&R Trak spacers, he can chime in on this.

Tim is right, you need to check both offset and tire width.
I have SSR 18x7, 235/60/18 tires, and +42 with 25mm wheel adaptors, w/o wheel adaptors tires would rub on both front and back.

sorry im not very good with rims and wheels. how do i check the offset?

TunedRX300

There should be either a label or an engraving inside the rim that tells you the offset.

but i didnt buy the rims yet because i want to make sure they will fit and work on the car before i buy them.

Rx300Mat

Fortunetly i didnt need wheel adaptors i have a direct fit cause i did all the specification homework before i bought them. I will try and post some pics of my car soon enough the only pic i have is my avatar at the moment.

You can ask the seller or manufacturer, if they are unable to provide one, don't buy it from then.
The stock RX300 setup has ~12mm between the tire and the rear strut, anything > +35 (stock rim offset) or bigger tire will eat into that margin.

Tuned, what tires are you running right now? Brand/size info please.

TunedRX300

Pirelli Scorpion Zero, 235/60/18. I plan to give BFGoodrich g-Force KDWS 245/55/18 a try after Pirelli tires wear out, just to see how handling feel with 245 tires.

My 00 is lowered and riding on 19'. No rubbing on struts, springs, fenders.
