New Rims need confirmation on tyre size.

I bought some new Volk GTS Rims, 18x9 +43 and 18x10 +43 for my JDM supra which has the factory bilstein shock option. I've asked around about tyre size and have got a couple recommendations and looked at some charts but am still terrified of ordering a tyre that will rub or won't fit.

235/40 R18 for the front

285/35 R18 for the rear

This is one of the recommendations from where I got the wheels (US) source. Unsure if the car being JDM with the stock 16" wheels would have an affect on them.

Any help or recommendations appreciated. You guys know more about JDM than most of the other forums.

I did recently post a tyre width chart with all this data on, i'll have to dig it out if i can find it

 

Here you go

 

 

Rim width---Min tyre width---Ideal tyre width----Max tyre width

 

7.0 inches-----195 mm--------205 or 215 mm-----------225 mm

 

7.5 inches-----205 mm--------215 or 225 mm-----------235 mm

 

8.0 inches-----215 mm--------225 or 235 mm-----------245 mm

 

8.5 inches-----225 mm--------235 or 245 mm-----------255 mm

 

9,0 inches-----235 mm--------245 or 255 mm-----------265 mm

 

9.5 inches-----245 mm--------255 or 265 mm-----------275 mm

 

10.0 inches----255 mm--------265 or 275 mm-----------285 mm

 

10.5 inches----265 mm--------275 or 285 mm-----------295 mm

 

11.0 inches----275 mm--------285 or 295 mm-----------305 mm

 

11.5 inches----285 mm--------295 or 305 mm-----------315 mm

 

12.0 inches----295 mm--------305 or 315 mm-----------325 mm

 

12.5 inches----305 mm--------315 or 325 mm-----------335 mm

Yah I found that in a search but I'm more inquisitive about the height of the tyre and that only shows width. Fenders are not rolled or cut and I would like to stay away from having to modify them.
