3GS wheel thread
Hey everyone, I just picked up some new wheels and am wondering what tire sizes to get.
They are 20x9.5 +38 and 20x10.5 +38.
I entered the information into the tire size calucator on 1010's website and it seems 235/35/20 (f) and 265/30/20 (r) would be within 3% of factory diameter, but since the wheels are semi-aggressive, would you think those tire sizes would minimize on rubbage or do you think I should go with more of a stretch? (such as 225 (f) and 245 or 255 (r) )

I agree your specs even though your wheel is a 1/2 wider your offset is close to 1/4 less aggressive then mine at +22 I sit almost perfectly flush at my ride height, from the ground to the highest point of my fender arch 25 inches. I do have my fenders shaved and don t rub unless I have the wheel turned and hit a bump. I am running a 245/30 in the front which is almost an exact match to factory overall diameter the 235/35 is about 3/4 of an inch larger than my tire I believe

Thanks for the knowledge and suggestions. So it seems the consensus for the front tire size is 245/30/20.
I just wonder if a 225/35/20 would offer more of a "cushion" for the wheels due to a slightly larger sidewall. Overall diameter is about .5" larger with this size.
@lkapimp216 - At your current height and offset, did you rub bad before the fender shave? When you shaved the fronts, were you able to retain the fender liner?
@msgs350 - Thanks, my car is RWD and I'm trying to achieve a nice flushed look
@IXI187IXI - Thanks for the tips!
@username32 - I'm hoping have my Tanabe sustec pro 5 installed soon and am trying to achieve a drop with no gap between the tire and fender. I've seen a 245/35/20 stretched on a 10" wheel before so maybe a 255/30/20 would work on a 10.5" wheel?
Here are some pics of test fitting 20x8.5 +25 and 20x10 +25 with 225/35/20 (f) and 245/35/20 (r):
Here are the wheels I need tires for:

I had my fenders shaved for a set of 22s I had so when I put the 20s and coilovers on it was already done. A 245 is going to stretch more on your 9.5 wheel than my 9 so you should be fine with your offsets. I have most of my liner

Before you guys make a comment about it needs to be lowered and wheels staggered, 
it is almost impossible to get a Lexus dealer to lower or try a staggered set of wheels and tires...That said I sold this set to a Lexus dealer and the car lasted less than 2 hours in the showroom before an elderly lady drove it home.

Has anyone ever heard of a tire mounting machine bending a rim? I just had my tires mounted on my brand new wheels and now there is a very slight bend on the lip. When the tires were mounted, the face of the wheel was faced down on the machine. Do you think the 4 hydraulic clamps have enough force to bend the lip?

that elderly lady will love the rough bumpy ride on those 20's.
