    I have 225/45/R18, 91w tires. I would like to see wheels that fit those tires to go on an 06 Cadillac STS. Please let me know if this is possible, I know stock size is 17, and two different sizes also.

      In the door post of my 2005 Cadillac STS, it says the front tires are 235/50/17 and the rear tires are 255/45/17. Your info only shows the 235. I was trying to find out if the rear rims were wider....and if I could run 275/40/17 tires on them.

        Hi, Doyle Williford! Thanks for the information, we have updated the data. 275/40/17 bit low for use with OEM 235/50/17 - rear axle will lower then the front to 8mm. I can recommend you the use 17x8J with 245/45 at the front and 17x9.5 with 275/40 rear.

          Hi Oleg, I am a little lost trying to find this info. Would you be able to help me out. I have 17x8JX48 rims on my Caddy. Can I replace these with 17x8J48?

            Hi, Mark! I think 17x8JX48 and 17x8J48 it's a same. Any rims 17" diameter with 7.5J-8.5J width and with offset in the 45-55mm range will work well. Dont forget about bolt pattern 5x115 and hub bore 70.3. I hope the information will be useful.

              Thanks Oleg, I am fairly confident the rims will work. I am more curious on the difference in the rim number and what the J and JX mean.

                I think 17x8JX48 just incorrect entry. J, JJ, K, JK - rim contour designations, It determines where the balancing weights attached - on the front of the rim or inside rim on the glue. Almost all modern cars use J and JJ rims, don't heard about JX contour. Any way it is more aesthetic parameter and does not require much attention.

      ...not sure on what’s the best / biggest / widest / maximum tires or rims will fit your car?

      Write about the tires you are currently driving on.
