I tried searching and I couldn't find the exact answer to my question...

I have 19" OEM Rays. On the back I have 245x40's now. My car isn't lowered or anything but I can't figure out if I should run 265x35 or 265x40? I figured the 265x40 since I'm only changing the width, and if I run the 35's it would have a large gap.

I'm not entirely sure though how this works..

So besides the speed difference, they 265x40 will fit without rubbing correct? I assumed they would because they are still the same height. This is my main concern

 

yea you wont have rubbing issues if you have stock height and no spacers. But 265/40r19 is a fat tire.

 

I'm looking for a fat tire, just dont want rubbing issues lol. Thanks for the help

 

I'm running stock tire sizes on my 19" Rays. I love it.

 

I would suggest against that 265/40. A bit taller than what will fit w/out rubbing. The 35 series is a tad off also, but better. Best fit, and most commonly used, is the 275/35-19.

 

^Best fit??? A 275 is a little wide for an 8.5" wheel

 

im running a 275 on a 11 and im stretched lol 275 on a 8.5 would look odd

 

Sorry, I was looking at the wrong wheels. The 265's mentioned above still need at least a 9" wheel. Not much you can do with that 8.5" rear wheel.

 

It's a little stretched looking but nothing too crazy.

 

hi i have the stock rays size 19 .. and im waondering on my rears if i can fit 275/35/19?!?!?!?!?1? help in need of ne tires now

 

If you read the above posts (just a few above ), you'll see the consensus is a 275/35/19 is a huge *** tire for an 8.5" wheel.

 

yeah but it would fit with no rubs or any problems correct??? help thanks u

 

Yes, technically it will fit but street tires that wide are designed for a minimum wheel width of 9" from the manufacturers. The sidewalls will probably bulge, the rear end will feel more loose since the wheel will be allowed to "float" more, and I'm curious to know the chances of an oversized tire coming off the wheel if it were to go flat. Its easy, just buy a tire that fits.
